Rockwell hardness test reference block

for Brinell hardness testfor Leeb hardness testfor micro Vickers hardness tests

Product overview
Euro Products manufactures precision-calibrated hardness reference blocks (test blocks) designed to provide a reliable benchmark for hardness testing equipment. Blocks are produced to tolerances often tighter than applicable international standards to improve hardness uniformity and accuracy in routine quality control.

Supported test methods

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

Availability
Full reference block hardness value ranges are provided in a complementary full-range table available from the manufacturer.

Manufacturing and quality assurance
Blocks are manufactured from selected materials, heat-treated, precision-ground and lapped to achieve stable, repeatable hardness values. Each block is calibrated using certified calibration machines and processes; Euro Products aims for tolerances tighter than applicable international standards to improve uniformity and repeatability.

Certification
Calibration and quality systems are maintained to accredited standards (ISO 17025:2017). The trademark Euro Calibration™ is associated with the calibration service.

Applications
Hardness reference blocks are intended for routine verification and calibration of hardness testers in industrial, laboratory, construction and quality-control environments to ensure accurate test results and regulatory compliance.
