The NG-ISCC Series Low Temperature Chamber is designed to condition Charpy impact specimens at controlled sub-zero temperatures prior to testing. It cools specimens uniformly and maintains a stable setpoint to support consistent, repeatable results.
Available conditioning targets include -30°C, -60°C, -80°C, -100°C, and -196°C, depending on the selected model.
The system is engineered around thermal balance and circulation to help minimize temperature gradients between specimens and across the chamber volume. A high-precision self-adjusting controller and platinum–iridium sensor provide accurate monitoring and straightforward operation.
For cooling performance across the full range, the series uses two proven approaches. NG-ISCC-60 and NG-ISCC-80 rely on compressor-based refrigeration for stable low-temperature conditioning. For extended ultra-low capability, NG-ISCC-100 and NG-ISCC-196 use liquid nitrogen cooling to reach and maintain the lowest temperature setpoints.
The NG-ISCC Series is used in materials testing labs and quality control environments that perform low-temperature Charpy impact testing, where specimens must be conditioned to a defined temperature before being transferred to the pendulum impact tester.
It is commonly applied to metallic materials and alloys evaluated for toughness and brittle-to-ductile transition behavior, including carbon and stainless steels, aluminum alloys, and nickel-based alloys, as well as weld procedure qualification and production lot verification programs.

This chamber is designed to pre-condition Charpy impact specimens to a controlled sub-zero temperature before you break them on a pendulum impact tester. In a typical Charpy workflow, it brings specimens to the target temperature, stabilizes them, and helps you transfer them for testing with less temperature drift, improving repeatability from specimen to specimen.
It is built to cool specimens evenly and maintain a stable setpoint so your batch sees consistent conditioning. The design emphasizes thermal balance and circulation to reduce temperature differences across the chamber and between specimens.
Different NG-ISCC models support different conditioning targets, including options down to ultra-low temperatures. Depending on the model, cooling is achieved with either compressor-based refrigeration or liquid nitrogen for the lowest setpoints.
If you want to confirm the best NG-ISCC configuration for your specimen volume, target temperature, and transfer workflow to the impact frame, use learn more or request a quote.
Charpy impact energy is highly temperature-sensitive, so consistent pre-test conditioning is one of the biggest levers you have to reduce scatter. Conditioning in this system brings each specimen to the same defined sub-zero target and holds a stable setpoint, so differences in absorbed energy are driven more by the material and notch quality, not by unintended temperature variation.
This chamber is designed to cool specimens uniformly and limit temperature gradients through thermal balance and circulation. A self-adjusting temperature controller and platinum–iridium sensor help monitor and regulate the conditioning temperature, supporting tight control with ≤ ±0.5°C accuracy and 0.01°C resolution.
In day-to-day ASTM E23 and ISO 148 workflows, repeatability improves further when you standardize handling around the chamber, for example:

This system is a specimen conditioning chamber only. It is used to cool and stabilize Charpy impact specimens to a controlled setpoint before testing, then the actual impact test is performed on a separate pendulum impact tester.
In a typical low-temperature Charpy workflow, you load specimens into the chamber, allow them to reach temperature uniformly, then transfer them to your impact frame for the strike and energy measurement. The NG-ISCC Series is built around stable temperature control and circulation to help reduce temperature variation across the chamber, supporting more consistent pre-test conditioning.
If you want to confirm the best NG-ISCC model for your target temperatures and your Charpy testing workflow, review the details under learn more and reach out to request a quote.
This system is intended to condition metal Charpy impact test specimens to a controlled sub-zero temperature before they are transferred to a pendulum impact tester.
In day-to-day lab and QC use, it is commonly applied to Charpy specimens machined from metallic materials and alloys such as carbon steels, stainless steels, aluminum alloys, and nickel-based alloys.
It is also a practical fit for weld procedure qualification and production verification work, where you may be conditioning base metal, weld metal, or HAZ Charpy specimens as required by your method. The exact specimen loading approach depends on your specimen geometry and quantity, and how you want to stage specimens for quick transfer to the impact frame.
If you want to confirm the best NG-ISCC configuration for your specimen style and workflow, learn more or request a quote.
The NG-ISCC model selection is driven by the lowest conditioning temperature you need to achieve and hold. Each model is named for its minimum temperature capability, and all models cover common sub-zero setpoints that fall within their rated temperature range.
Model-to-setpoint matching is typically:

During conditioning, the NG-ISCC Series is available with cooling ranges from -60°C to +30°C, -80°C to +30°C, -100°C to +30°C, or -196°C to +30°C, depending on the model you select. Temperature control accuracy is specified at ≤ ±0.5°C, with 0.01°C instrument resolution.
Model choice drives both the low-end temperature and the cooling approach. The -60°C and -80°C versions use compressor refrigeration, while the -100°C and -196°C versions use liquid nitrogen to reach ultra-low setpoints.
In day-to-day use, the tightness of specimen conditioning at the target temperature is influenced by practical factors like specimen quantity and mass, bath circulation and loading pattern, lid or door open time, and the soak approach used before transfer to the impact frame.
If you want to confirm the best NG-ISCC configuration for your target temperature and conditioning workflow, use learn more or request a quote.
Ultra-low conditioning to −196°C is supported on the NG-ISCC-196 model, which uses liquid nitrogen cooling for specimen conditioning prior to pendulum impact testing.
The NG-ISCC Series is offered in multiple temperature configurations, so the minimum achievable temperature depends on the model selected:
For transition-curve work and pre-test conditioning to ASTM E23 or ISO 148, the key is repeatable temperature control and uniform conditioning before transfer to the impact frame. This system uses a self-adjusting temperature controller with a platinum–iridium sensor, with temperature control accuracy specified at ≤ ±0.5°C and 0.01°C resolution.
If you want to confirm the right configuration for your conditioning temperatures and LN2 setup, review the chamber details and then learn more or request a quote.
In typical operation, this chamber is used to condition multiple Charpy impact specimens at the same time as a batch at one controlled setpoint, so a full series can be stabilized before transfer to the impact tester.
The practical number of specimens you can condition simultaneously depends on how you configure the load for consistent cooling and temperature stability. Key drivers are specimen size (full-size vs sub-size), how much spacing you maintain for uniform circulation, and the target temperature you are running, with NG-ISCC models available for conditioning down to -196°C depending on the version selected.
For repeatable results, most labs avoid overcrowding and keep the same loading pattern from run to run so the soak and temperature uniformity are consistent.
If you want to confirm the best NG-ISCC model and the right batch loading approach for your specimen geometry and workflow, learn more or request a quote.
This chamber is intended for conditioning Charpy impact specimens for standard low-temperature testing workflows, including ISO 148 and ASTM E23. In general, the chamber’s temperature conditioning is not notch-specific, so it can be used for standard Charpy specimen formats as long as your specimens physically fit the chamber’s specimen holding arrangement and can be conditioned uniformly.
In practice, the supported Charpy specimen geometry is driven by how you plan to stage the samples for consistent temperature soak prior to transfer to the impact frame. That is what keeps your brittle-to-ductile transition and lot-to-lot comparisons meaningful.
To confirm the best fit for your lab, the key factors are typically:
If you want to confirm the right configuration for your specific Charpy specimen geometry and conditioning routine, please learn more and request a quote.
There can be limitations, and they typically come down to how your specimens physically fit and how they are supported while the chamber is conditioning them. This system is intended for Charpy impact specimens, so the most straightforward setup is using specimen holders or baskets sized for common Charpy geometries and arranged to maintain consistent cooling across the batch.
If you plan to run non-standard specimen dimensions, unusual orientations, or higher part counts per cycle, the holder or basket design becomes important. Spacing and layout should support good circulation and thermal balance so you do not create warm spots or temperature gradients from contact points, stacking, or overcrowding.
For most labs, the key selection factors are:
If you want to confirm the right basket or holder approach for your specimen dimensions and workflow, review learn more and share your specimen details through request a quote.
This chamber is commonly used in weld procedure qualification style Charpy programs, and it can typically be set up to condition sub-size Charpy specimens as long as the specimens can be loaded securely and exposed to uniform circulation in the chamber before transfer to the impact tester.
Whether sub-size weld specimens fit cleanly comes down to how you plan to stage them inside the chamber. The key drivers are the sub-size geometry you are using, how the specimens are supported or separated during the soak, and how many you want to condition per cycle without specimens touching each other.
For weld testing, the practical goal is repeatable temperature stabilization and a smooth handoff to the Charpy frame using your lab’s handling approach. The NG-ISCC series is built for controlled sub-zero conditioning ahead of Charpy testing, with model selection based on the temperature target and cooling approach.
If you want to confirm the right configuration for your sub-size specimens and weld test workflow, please learn more and request a quote.
This chamber is built around conditioning Charpy impact specimens to a stable target temperature and holding that setpoint for the required soak. In typical use, you select the desired setpoint and let the system stabilize rather than running a multi-step temperature program.
The NG-ISCC Series is offered in models intended for specific low-temperature targets, with available conditioning targets including -30°C, -60°C, -80°C, -100°C, and -196°C depending on the model you choose.
Whether a workflow truly needs temperature steps usually depends on your lab procedure and test method requirements, plus practical factors like specimen mass and quantity, soak time expectations, and whether you are using compressor-based refrigeration models or liquid nitrogen models for ultra-low setpoints.
If you want to confirm the best configuration for your target temperatures and conditioning workflow, use learn more and request a quote.
Pull-down time from ambient to a target setpoint is application-dependent, and it is best treated as a function of your chosen NG-ISCC model, the temperature difference to the setpoint, and the specimen load you are conditioning.
The NG-ISCC-60 and NG-ISCC-80 use compressor-based refrigeration, while the NG-ISCC-100 and NG-ISCC-196 use liquid nitrogen for ultra-low setpoints. In practice, deeper setpoints and heavier loads generally require more time to cool and stabilize, even when the chamber control is already holding a steady temperature.
For consistent Charpy conditioning, “ready to test” usually means both the chamber and the specimens have stabilized. The biggest drivers are typically:
If you want to confirm expected pull-down and soak time for your setpoint and specimen batch size, please learn more or request a quote.
This chamber is designed with thermal balance and internal circulation to help reduce temperature gradients from specimen to specimen and throughout the chamber volume during low-temperature conditioning for Charpy impact testing.
In practice, uniformity is driven by a combination of the circulation approach, the cooling medium used in the chamber (ethanol or another non-freezing solution), and steady temperature control using the system’s controller and sensor. Your specimen mass, how many samples you load at once, and how tightly they are grouped can all influence how quickly everything reaches the same stabilized condition.
To help minimize gradients in day-to-day QC and lab use:
If you want to confirm the best configuration and conditioning workflow for your specimen size, batch quantity, and target temperature, learn more or request a quote.
The NG-ISCC Series is specified with temperature control accuracy of ≤ ±0.5°C and an instrument resolution of 0.01°C. These values are listed the same across the NG-ISCC-60, NG-ISCC-80, NG-ISCC-100, and NG-ISCC-196 models.
In practice, accuracy describes how closely the chamber controls to the target setpoint, while resolution is the smallest temperature increment the controller can display and adjust.
For Charpy specimen conditioning, the temperature consistency you achieve at the specimen also depends on typical workflow factors like specimen loading density, soak time at setpoint, and how often the lid is opened while staging samples for the impact test.
If you want to confirm performance for your target temperature and specimen handling routine, review the system details under learn more and share your setpoint and throughput needs to request a quote.
Temperature uniformity is typically verified by performing a simple multi-point temperature survey at the same time the chamber is controlling at your target setpoint. In practice, you place independent reference temperature probes at representative locations within the working volume, allow the system to stabilize, then confirm the readings are consistent across positions while the controller is holding the set temperature.
A common verification approach in a Charpy workflow includes:
Results can vary with loading pattern, specimen mass, bath medium and level, circulation conditions, and the selected cooling approach (compressor-based vs liquid nitrogen models).
If you want to confirm the right verification method and probe placement for your setpoint and specimen load, review the chamber details under learn more and request a quote for the recommended setup.
This chamber is built around a high-precision, self-adjusting temperature controller using a platinum–iridium sensor for closed-loop monitoring and stable conditioning of Charpy impact specimens. External probe verification and any offset correction are typically handled as part of your lab’s temperature verification and calibration workflow, and the exact approach depends on the controller configuration and your quality requirements.
For verification, labs commonly place a calibrated reference probe in the working zone where specimens sit, then compare the reference reading to the chamber display at the soak temperature used for testing. This helps confirm what the specimens are actually seeing right before transfer to the impact frame.
For offsets, some teams prefer entering a correction in the controller (when enabled), while others document a correction factor and leave the control loop unchanged. The best path usually depends on your internal procedure, whether you are verifying one point or multiple setpoints, and how you need to document results for audits and method reporting.
If you want to confirm the best verification and offset approach for your NG-ISCC model and your target temperatures, use learn more and request a quote with your setpoints, probe type, and documentation expectations.
Out-of-tolerance alarming and any interlock behavior are typically configured around your temperature-conditioning workflow and how you want the chamber to signal or prevent specimen transfer when the setpoint is not stable.
This system uses a high-precision, self-adjusting controller with a platinum–iridium temperature sensor for accurate monitoring during Charpy specimen conditioning.
In practice, the right alarm or interlock approach depends on a few items:
If you want to confirm the best controller alarm limits and any interlock integration for your procedure, review the system details under learn more and share your requirements via request a quote.
This conditioning system is specified to support Charpy specimen conditioning workflows aligned with ISO 148 and ASTM E23. It is also listed with ASTM E74 (Class AA) under the Standards section for the NG-ISCC Series.
In practice, meeting ASTM E23 or ISO 148 conditioning requirements depends on running the chamber to the method-defined specimen temperature and maintaining stable conditioning before transfer to your pendulum impact tester. Your lab procedure typically defines the setpoint, soak approach, and transfer handling needed to keep specimens at the required temperature at the moment of impact.
If you want to match a specific Charpy method setup, key factors usually include the target temperature range, specimen quantity and geometry, and how specimens are moved from the chamber to the impact frame.
If you want to confirm the right configuration and documentation for your ASTM E23 or ISO 148 workflow, use learn more or request a quote.
For ASTM E23 and ISO 148 Charpy programs, this system is typically supported with documentation that ties the chamber’s conditioning function to your lab’s controlled-temperature workflow, including the unit identification details and the operating guidance needed to run repeatable soak and transfer routines.
Documentation commonly provided or available for your quality file includes:
ASTM E74 is generally associated with force-proving and load measurement traceability. If your quality system calls out ASTM E74 Class AA documentation as part of your broader testing program, the right approach is to match the documentation package to the instruments that fall under that standard and keep the chamber documentation aligned to specimen temperature conditioning.
If you want to confirm the exact documentation set for your method and audit needs, learn more and request a quote.
Power requirements for the NG-ISCC Series depend on the specific model and how it is configured for your facility’s utilities. In general, NG-ISCC-60 and NG-ISCC-80 are compressor-based refrigeration systems, while NG-ISCC-100 and NG-ISCC-196 are liquid nitrogen cooled, so the electrical service and site connections are not identical across the lineup.
For accurate line specifications, the key items to align up front are your available facility power (voltage, phase, and frequency), the preferred connection style (hardwired vs. cord and plug), and whether a dedicated circuit is required for your lab. For liquid nitrogen models, you should also plan for the LN2 supply connection and appropriate ventilation practices around cryogenic use.
At a model level, here is what typically drives the utility differences:
If you want to confirm the exact electrical input and site line requirements for your NG-ISCC model and location, use learn more and then request a quote with your facility power details and target conditioning temperature.
For the liquid nitrogen cooled NG-ISCC-100 and NG-ISCC-196, the best practice is to feed the chamber from a liquid-withdrawal LN2 dewar with stable, regulated delivery pressure, using cryogenic-rated fittings and an insulated transfer line so the chamber can reach and hold the lowest setpoints without flow swings or icing at the connection.
Dewar pressure is typically set to whatever level your LN2 supply system needs to deliver steady liquid to the chamber’s inlet valve over your run duration. The right setting depends on your dewar style (pressure-building capability), the distance to the chamber, and how aggressively you are pulling down to temperature versus holding a soak.
For fittings and hose types, prioritize components intended for liquid nitrogen service and repeatable connect and disconnect work in a lab or production environment:
If you want to confirm the recommended inlet connection details for your exact NG-ISCC-100 or NG-ISCC-196 configuration and your dewar type, review the system on learn more and send your LN2 supply details to request a quote.
For the NG-ISCC Series, the cooling bath is intended to be filled with ethanol or another non-freezing solution suitable for the target conditioning temperature.
In practice, the “right” cooling medium depends on your lowest setpoint, how quickly you need the bath to stabilize, and your facility’s EHS requirements for handling and storing flammable liquids. The goal is a stable, well-circulating bath fluid that will not freeze, thicken excessively, or create inconsistent specimen temperatures during the soak.
When evaluating an alternate non-freezing solution, confirm these basics before use:
If you want to confirm the best bath fluid for your temperature target and shop safety requirements, review the system details under learn more and send your setpoint and workflow details to request a quote.
Plan for normal lab ventilation and basic spill control during installation, with extra attention if you are installing a liquid-nitrogen-cooled model or using a non-freezing liquid medium such as ethanol. In most labs, no dedicated exhaust duct is required, but the right setup depends on your NG-ISCC configuration and your site safety rules.
For NG-ISCC-60 and NG-ISCC-80 (compressor refrigeration), provide open airflow around the unit so heat can dissipate and controls stay stable. For NG-ISCC-100 and NG-ISCC-196 (liquid nitrogen cooling), treat nitrogen boil-off as a room ventilation and oxygen-deficiency consideration. Many facilities address this with appropriate room ventilation practices, cylinder handling, and EHS-required monitoring where applicable.
For spill containment, the chamber uses a non-freezing cooling medium (commonly ethanol or a similar solution). Set the chamber on a chemical-compatible secondary containment tray or in an area where small leaks can be safely managed, and follow your facility’s flammability, PPE, and cleanup procedures for the selected fluid.
If you want to confirm the right installation approach for your model and cooling medium, review the system details and then learn more or request a quote with your target temperature and whether you are considering compressor or liquid nitrogen cooling.
This system is typically installed on a stable, level bench or a dedicated stand, as long as the surface can support the unit and you have a clean path for utilities and routine specimen handling. For clearance, plan space so the door can open fully and operators can load and remove Charpy specimens quickly without obstruction, while also preserving access for connections and service.
Recommended clearance around the enclosure depends on the selected NG-ISCC model and your workflow, especially whether you are using compressor cooling or liquid nitrogen cooling, how you route lines and power, and how close you want the chamber positioned to the impact frame to minimize specimen warm-up during transfer.
In practice, you should allow working space for:
If you want to confirm the best installation layout for your specific NG-ISCC configuration and specimen transfer process, use the product page to learn more or request a quote.
Accurate conditioning depends on keeping the chamber in a stable, indoor lab environment so it can hold a steady specimen soak temperature and recover quickly after loading or unloading. Large swings in room temperature, strong drafts, and high humidity can increase frosting and condensation, which can affect how consistently specimens reach the target setpoint.
This system conditions Charpy specimens at controlled sub-zero temperatures (model-dependent) using a non-freezing bath medium such as ethanol, with compressor-based or liquid-nitrogen cooling depending on the model. Ambient conditions mainly influence heat leak into the chamber and moisture load on cold surfaces, especially when running at the lowest setpoints or when the lid is opened frequently.
For best repeatability in production and QC workflows:
If you want to confirm the right site conditions for your setpoint, model choice, and specimen throughput, review the details under learn more and send your application notes to request a quote.
This chamber is most commonly paired with NextGen’s pendulum Charpy impact frames used for low-temperature Charpy workflows, where specimens are conditioned to a controlled setpoint and then transferred directly to the impact tester for the break.
In day-to-day QC and lab use, the most frequent pairings are the Class D Single-Column Charpy Impact Tester and the Class G Single-Column Charpy and Izod Impact Tester. For higher-energy Charpy programs or more advanced system configurations, labs also pair the NG-ISCC with the Class H Servo-Motor Dual Column Charpy Impact Tester. For lower-energy Charpy and Izod testing, the Class J Charpy and Izod Automatic Impact Testing System is another common match.
If you want to confirm the best pairing for your specimen type, target temperature, and throughput, please learn more or request a quote.
These items are typically configuration-dependent. The chamber can be supplied with the specimen handling accessories you need, but racks, baskets, and transfer tongs are often selected to match your specimens, your workflow, and how you transfer conditioned Charpy samples to the impact tester.
Most labs choose the accessory set based on a few practical factors:
If you want to confirm what is supplied for your exact NG-ISCC configuration, including the right rack or tong style for your specimens, review learn more and send the details through request a quote.
Select a heating and cooling GenChamber when your Charpy or Izod workflow requires both sub-zero conditioning and elevated-temperature conditioning in one system. The NG-ISCC Series is primarily a low-temperature conditioning chamber for Charpy specimens, with model-dependent ranges that cover sub-zero setpoints down to ultra-low temperatures and up to about +30°C.
GenChamber is typically the better fit when you need:
Stay with the NG-ISCC when your test plan includes colder conditioning targets, such as -100°C or -196°C, since those models are specifically configured for deeper sub-zero conditioning, including liquid nitrogen-cooled versions.
If you want to confirm the right chamber based on your required temperature points, specimen flow, and utilities, start with learn more and then request a quote for a configuration recommendation.
For a well-controlled Charpy program, the most reliable approach is to use a dedicated specimen notching and broaching machine to cut consistent V and U notches, then confirm the notch geometry on an optical notch verification system before testing. This combination reduces operator-to-operator variation and helps keep your impact results tied to the notch requirements of your Charpy method.
In practice, labs typically standardize on tools like these:
A good habit is to verify notch profile at setup, after any knife replacement, and whenever you see unexpected shifts in absorbed energy or fracture appearance.
If you want to confirm the right notch-making and verification setup for your specimen geometry and Charpy method, learn more, learn more, or request a quote.
This chamber is built around accurate setpoint control and clear temperature monitoring during Charpy specimen conditioning. Temperature logging, setpoint “recipe” programming, and USB data export are typically controller-dependent features, so they are best treated as configuration options tied to your documentation and workflow needs.
For impact testing labs, the right controller features usually depend on how you plan to prove temperature stability and soak conditions before transfer to the pendulum impact tester, especially when you are running multiple conditioning temperatures in a shift.
When specifying logging or export, a few details usually drive the best fit:
If you want to confirm the right controller configuration for your reporting and traceability needs, use learn more and send your requirements to request a quote.
Integration with an external temperature logger or a laboratory LIMS is typically achieved either by using an independent logger to capture the specimen soak temperature, or by connecting to the chamber’s control system if a direct data handoff is required. The best approach depends on how you need to store, time-stamp, and audit temperature records for your Charpy workflow.
This chamber is built around a precision temperature controller and sensor for monitoring and maintaining the conditioning setpoint. For traceable documentation, many QC labs place a calibrated probe in the working area or cooling medium, record the soak profile with their preferred logger, then link that record to the impact test report.
When specifying an interface, we typically confirm:
If you want to confirm the right integration path for your logger or LIMS, review the chamber details under learn more and send your data requirements through request a quote.
For NG-ISCC configurations that use liquid nitrogen cooling, safe operation is typically achieved by combining controlled LN2 delivery to the chamber with facility-level safeguards that prevent cryogenic splash hazards and reduce oxygen displacement risk from nitrogen boil-off.
In practice, the most important protections are usually tied to how the LN2 supply is implemented, including secure, insulated transfer plumbing, stable supply control hardware, and correctly rated pressure relief on the LN2 source. The exact safety package depends on your LN2 supply method, the chamber placement, and your lab’s operating procedure for loading and transferring Charpy specimens.
Most labs also implement additional ODH and handling controls such as:
If you want to confirm the right LN2 interface, ventilation, and ODH approach for your site and workflow, learn more and request a quote.
This chamber is built around closed-loop temperature control using a high-precision controller and a platinum–iridium temperature sensor, and it can be specified with protective functions such as over-temperature limiting, low-level or low-supply monitoring, and sensor-fault alarm logic. The exact protections integrated on your system depend on the NG-ISCC model and the control and utility configuration selected.
Protection needs typically vary based on the cooling approach, since compressor-cooled models and liquid-nitrogen models manage different risk scenarios during low-temperature conditioning and soak prior to Charpy impact testing.
When you are confirming protections for ASTM E23 and ISO 148 workflows, the most common items to review are:
If you want to confirm the right protection package for your method and how you plan to run the chamber, review learn more and request a quote with your target temperature, cooling method preference, and whether the unit will run unattended.
For the compressor-based NG-ISCC models, routine maintenance is mainly preventive housekeeping that keeps cooling performance stable and helps you hold repeatable specimen conditioning temperatures. In day-to-day use, focus on cleanliness, airflow, and regular checks of the cooling medium and seals.
Because these chambers use a non-freezing liquid medium such as ethanol, good practice is to keep the fluid clean, at the correct level for your workload, and free of moisture or debris. Labs also typically perform periodic temperature verification checks to support consistent Charpy specimen soak conditions before transfer to the impact tester.
Common routine checks include:
If you want to confirm the right maintenance checklist for your setpoints, usage rate, and site conditions, learn more or request a quote for the configuration you are running.
Verify temperature accuracy at commissioning, after any relocation, and any time the chamber has been serviced, adjusted, or shows behavior that could affect specimen conditioning. After that, set a routine verification interval that matches your Charpy method requirements and your lab’s quality system, then recalibrate whenever the verification check indicates drift outside your acceptance criteria.
In practice, field verification is typically done by comparing the chamber’s indicated temperature to a traceable reference sensor placed where specimens are conditioned, then checking stability at the setpoints you actually run. This is especially important when you rely on tight control for Charpy conditioning, since the NG-ISCC Series is built around a self-adjusting controller and a temperature sensor to maintain consistent setpoints.
You may want to shorten your verification interval when any of the following apply:
If you want to align your verification and recalibration plan to your exact NG-ISCC model and your ASTM E23 or ISO 148 workflow, use learn more and request a quote.
To prevent contamination and ice or slush build-up in the cooling bath, focus on keeping water and shop-floor debris out of the cooling medium and minimizing how long the chamber is left open during specimen loading and unloading. Clean handling and consistent bath maintenance typically make the biggest difference in temperature stability and repeatability.
Good day-to-day practices include:
For ongoing control, set a simple change-out and inspection routine based on how often you run tests and how humid the area is. If you see cloudiness, particulates, or unexpected temperature behavior, it is usually time to clean the bath area and refresh the cooling medium.
If you want to confirm the best coolant, handling workflow, and maintenance routine for your NG-ISCC configuration and your Charpy conditioning method, please learn more or request a quote.
This chamber is supported through NextGen’s stocked consumables and spares approach, which is intended to speed up replacements and reduce downtime when service items are needed.
Because the NG-ISCC Series is offered in multiple models and cooling approaches, the exact spare sensor and controller components are typically matched to your specific configuration, including the selected temperature conditioning target and whether the unit is compressor-cooled or liquid-nitrogen cooled.
Seal and gasket needs are usually driven by day-to-day wear, frost control practices, and how frequently the door is cycled in production conditioning. Many labs also choose to keep a small “downtime kit” on the shelf for critical wear items to avoid schedule impact on ASTM E23 and ISO 148 workflows.

Long-term support can be set up through NextGen, including ongoing service help and annual calibration support. Many labs choose to formalize this as a recurring calibration and service arrangement so the equipment stays consistent for audit and quality requirements.
For temperature conditioning systems used ahead of Charpy impact testing, the right plan is typically driven by your internal calibration interval, required documentation, and how tightly you control specimen soak and transfer procedures. NextGen supports annual calibrations through accredited ISO laboratories for instruments that require it.
Beyond calibration, NextGen also supports the full lifecycle around the equipment, including warranty support and technical assistance when you need troubleshooting, adjustments, or guidance on maintaining stable conditioning performance.
