Frequently Asked Questions

How often should hardness test blocks be recalibrated or replaced?

Hardness test blocks should be recalibrated periodically (often annually) or replaced when their certified uncertainty expires, if they show significant wear or indentations outside the test area, or if they are dropped or damaged.

Can a hardness tester be accurately calibrated on-site at my facility?

Yes, many accredited calibration labs, like MQC, offer on-site calibration services using mobile laboratories that can replicate controlled environmental conditions, providing convenient and accurate calibration at your location.

Beyond calibration, what routine maintenance can I perform to help maintain my hardness tester's accuracy?

Regular cleaning of the indenter and anvil, ensuring the test area is free of debris, checking for loose components, and proper handling and storage of test blocks can significantly contribute to maintaining your hardness tester's accuracy between calibrations.

Why is it important to use certified reference hardness blocks for indirect calibration?

Certified reference hardness blocks provide a traceable standard with a known, accurate hardness value. Using them ensures that your instrument's readings can be directly compared and verified against internationally recognized standards.
