Specimen Size Effects in Charpy Testing: What Engineers Need to Know

31 March 2026

Charpy V-notch testing remains widely used because it offers a standardized and efficient way to evaluate impact behavior in metallic materials. In production, qualification, and failure analysis work, it is often used to compare toughness response across temperatures, material conditions, […]

Rock Core Prep Done Right: Why Trimming And End Grinding Matter

28 February 2026

Rock core testing provides the “intact rock” parameters engineers use to inform excavation strategy, stability checks, and deformation expectations in projects like mining, tunneling, and dams. Those lab programs typically report compressive strength (uniaxial or triaxial) and, when stress strain […]

UTM Grips And Fixtures: Types, Uses, And How To Choose

20 February 2026

Your UTM may be calibrated, but if the specimen slips, bends, or fails at the jaws, you’re not measuring the material, you’re measuring the setup. A universal testing machine can only capture true material behavior when the load is transferred […]

Pendulum vs Drop Tower Impact Testing: Which One Do You Need?

7 February 2026

Impact testing exists because many real-world failures happen under short-duration, high-rate loading such as drops, strikes, tool impacts, and brittle-fracture triggers. Charpy and Izod pendulum tests and drop-tower (drop-weight) tests are two of the most common lab ways to reproduce […]

Why Material Test Results Fail Audits: Equipment-Related Root Causes Labs Overlook

2 February 2026

If your lab has ever been told “your equipment is calibrated” and still walked out of an ISO/IEC 17025 or customer audit with findings, you’re not alone. Calibration certificates are important, but they’re not the same thing as audit readiness. […]

Hardness Testing Method Selection For Reliable QC: Rockwell vs Brinell vs Vickers vs Knoop

12 January 2026

Hardness testing is one of the fastest ways to confirm material condition in QC, R&D, and teaching labs. The problem is not getting a hardness number. The problem is getting a number that is consistent, comparable, and useful for a […]

GenTest 3.0: Test Control And Data Acquisition Software For NextGen UTMs

4 January 2026

How much time does your lab spend after the test: rebuilding methods, double-checking signals, and turning raw data into a report you can actually use? In QA/QC and repeatable R&D work, the bottleneck is usually everything around the run: method […]

Why Cheap Testing Machines Become Expensive Over Time

28 November 2025

At first glance, the offer may sound reasonable. The machine looks almost new, the price is far below market, and the seller insists it works perfectly. For many companies, especially under budget pressure, the savings seem too good to pass […]

Why Calibration Certificates Matter More Than You Think

20 November 2025

In many production environments, calibration certificates are seen as optional paperwork. Internal labs often run tests using their own machines, assuming accuracy by default. This mindset is common where companies aim to cut costs or avoid downtime. But skipping proper […]

Equipment Maintenance in Material Testing: Why It Cannot Be Ignored

12 November 2025

For many manufacturers, test equipment is treated as a one-time investment. It arrives calibrated, runs properly, and quietly performs its tasks in the background. That is, until the first unexpected malfunction forces production to stop. Neglecting maintenance rarely creates problems […]
