Standard Test Blocks

Calibrated and certified hardness test blocks are an important part of the hardness testing. QPREP hardness test blocks fulfill the requirements for testing according to following standards:

• DIN EN ISO 6506 (Metallic materials; Brinell hardness test)
• DIN EN ISO 6507 (Metallic materials; Vickers hardness test)
• DIN EN ISO 6508 (Metallic materials; Rockwell hardness test)
• DIN EN ISO 4545 (Metallic materials; Knoop hardness test)
• ASTM (E10, E18, E384)

These are essential for indirect calibration and periodic verification, as well as the results documentation.

• DAkkS calibration: according to current ISO and ASTM standards
• Permissible measurement deviation engraved
• Angular basic shape: optimal for automated periodic testing
• Easy data insertion into the documentation template
• Option: engraved grid lines
• Option: multiple calibrations
