ISO 6603-2 is a test method for determining the puncture impact behaviour of rigid plastics using an instrumented impact setup that measures force and deflection during impact.
It is commonly used when a force–deflection (or force–time) curve is needed for deeper impact characterization than a simple pass/fail or threshold-energy result. If you are unsure whether this instrumented method is the right fit for your material form or reporting needs, you can talk with our team.
ISO 6603-2: Plastics — Determination of puncture impact behaviour of rigid plastics — Part 2: Instrumented impact testing
This standard describes an instrumented puncture impact test for flat specimens of rigid plastics. The instrumented approach captures a response curve during the impact event, which is useful for comparing how materials absorb energy and resist puncture under controlled conditions.
The method is intended for material comparison and characterization under standardized conditions; it is not typically used as a direct design-allowables method for structural calculations.
Quick Definition
Document type: Test method (instrumented impact / puncture impact).
What it measures: Puncture impact response of rigid plastics using recorded force and deflection (or force and time) at a nominally constant striker velocity.
Typical output: A force–deflection or force–time curve plus derived puncture-impact properties reported per the standard’s requirements.
What This Standard Covers
ISO 6603-2 specifies how to run an instrumented puncture impact test on rigid plastics using flat specimens. The instrumented system measures the impact event (rather than only recording whether the specimen failed), enabling more detailed evaluation of impact behaviour.
The scope is aimed at rigid plastic specimens within a defined thickness range and allows specimens that are moulded, machined, cut from sheet, or taken from finished products, provided the specimen preparation and test conditions are controlled and reported consistently.
Why This Standard Matters in Testing
Instrumented puncture impact data is often requested when simple impact “threshold” metrics are not sufficient. Capturing the force–deflection response can help differentiate materials that may show similar overall impact energy but very different peak-force behaviour, stiffness during impact, or failure progression.
In QA/QC and R&D workflows, the method is commonly used to compare resin grades, evaluate processing effects (such as moulding or extrusion changes), or document changes due to reinforcement, fillers, or laminate construction.
Common Materials, Product Types, or Applications Covered
ISO 6603-2 is used for rigid plastics in flat-specimen form, including:
- Rigid thermoplastics (filled, unfilled, and reinforced compounds; sheet and moulded forms)
- Rigid thermosets (including filled/reinforced moulding materials, sheet, and laminates)
- Fibre-reinforced composites (thermoset or thermoplastic matrices, including various reinforcement architectures)
It is often applied to sheet products, moulded plaques, and laminate panels, and it can be used on specimens taken from finished products when comparative characterization is the goal.
Common Test or Verification Workflow
Most ISO 6603-2 programs follow a controlled workflow so results are comparable within a project or between labs.
Common workflow steps: Define specimen geometry and thickness per the standard, condition specimens as required, mount/clamp the specimen, apply an instrumented puncture impact at the specified striker velocity, record force and deflection (or force and time), and report the required derived values and test conditions.
Practical comparability note: Results are only comparable when specimen preparation, specimen thickness, and test conditions are kept consistent across the data set.
Equipment Commonly Used for This Standard
ISO 6603-2 points to an instrumented puncture impact setup capable of measuring the impact event, not just the outcome.
Common equipment: Instrumented falling-weight impact / puncture impact tester with a striker assembly, specimen clamping fixture, force measurement, deflection (or displacement) measurement, and a data acquisition system to capture force–deflection or force–time response.
Common accessories: Environmental conditioning capability (when testing across temperatures), specimen thickness measurement tools, and software for curve capture and reporting aligned to the standard.
If you are configuring an instrumented puncture impact system for a specific material thickness range or reporting format, you can request a detailed quote for an equipment package matched to your lab’s test plan.
How to Read This Designation or Revision
Designation: ISO 6603-2 refers to Part 2 of the ISO 6603 series for puncture impact behaviour of rigid plastics.
Revision format: A citation such as “ISO 6603-2:2023” includes the publication year, which matters because fixture details, data reduction, or reporting requirements can change between editions.
Related part: ISO 6603-1 covers non-instrumented puncture impact testing, while ISO 6603-2 covers the instrumented method used when a recorded curve is required.
Related Standards, Methods, or Frameworks
ISO 6603-2 is part of the ISO 6603 series for puncture impact testing of rigid plastics. When instrumented curve data is not required and a threshold-style result is acceptable, ISO 6603-1 is often referenced instead.
For thin materials outside the stated thickness range, other ISO impact methods may be more appropriate depending on the specimen form and performance question.
