How Hardness Reference Blocks Work
Calibration and Verification Principles
A hardness tester measures the hardness of the block, and the result is compared with its certified value.
Certified Reference Values
Each block comes with a traceable hardness value established by recognized standards.
Measurement Comparison Process
Operators perform multiple tests to ensure accuracy and repeatability.
Types of Hardness Reference Blocks
Rockwell Reference Blocks
Used for Rockwell hardness testing machines.
Brinell Reference Blocks
Suitable for larger indentation testing methods.
Vickers Reference Blocks
Ideal for precise and micro-level hardness measurements.
Micro Hardness Reference
Designed for testing small areas and thin materials.
