Reference Blocks

Hardness Testing Reference Blocks

Certified Hardness Reference Blocks for Accurate Calibration

At Euro Products, we manufacture precision-calibrated reference blocks that exceed industry standards, providing a dependable benchmark for your testing requirements. Where possible we manufacture our reference blocks to tolerances tighter than required by the relevant international standards. This helps us achieve much tighter uniformity of hardness across all our reference blocks, and provides greater accuracy for our customers in their day-to-day quality control requirements. 

We manufacture reference blocks for the following test methods:

  • Rockwell Hardness methods all 30 Scales
  • Macro Vickers methods 2 Kg to 100 Kg
  • Micro Vickers methods 1g to 1 Kg
  • Low Load Brinell methods 1kg to 187.5 Kg
  • Heavy Load Brinell methods 250 Kg to 3000 Kg
  • Micro Knoop Methods 1g to 2 Kg
  • Leeb Methods
  • UCI Methods

Manufacturing and Quality Assurance

Our reference blocks are made from carefully selected materials, heat-treated, precision-ground and lapped to achieve stable and repeatable hardness values. Each block undergoes rigorous calibration using certified calibration machines, ensuring compliance with international hardness testing standards.

Applications

Hardness reference blocks are used for routine verification and calibration of hardness testers in industrial, laboratory, construction and other quality control settings. They are essential for maintaining accurate test results and ensuring compliance with industry regulations.
