: Triangular Test Blocks from MPA

Calibrated Testblocks

We supply calibrated and tracable testblocks. The certificates are issued by MPA NRW in Germany and are according to EN ISO Standards. Vaildity of the certificate is 5 years. When ordering, please specify the testblock accordingly:

For Vickers and Knoop: Testload and hardness of the block (e.g. 560HV2 or 560 HK2)

For Rockwell: Rockwell scale and hardness of the block (e.g. HRC62)
