Frequently Asked Questions

AI
A hardness block is a calibrated reference standard used to verify the accuracy of a hardness tester. The tester is the device that measures the material's resistance to indentation. Blocks ensure your tester remains precise over time.
Choose Rockwell (HRC/HRB) for metals like steel and aluminum. Use Shore A or D for rubber and plastics. Vickers or Brinell scales are often used for finer grain structures or softer metals. Select based on the material you test most frequently.
Hardness blocks should be recalibrated periodically, typically every one to two years, depending on usage frequency and environmental conditions. Regular verification against a certified standard ensures your testing results remain reliable and compliant.
