We also subject each diamond indenter to a strict performance test before it is approved and certified for sale. All diamonds and indenters are supplied with a traceable ISO/IEC 17025 accredited certificate and meet the requirements of ASTM-E18 and ASTM-E384. 

We offer a complete range of Standardized Rockwell Hardness Test Blocks and Indenters. HRC Test Blocks are directly traceable to NIST. Each Standardized Rockwell HardnessTest Block is supplied with a traceable ISO/IEC 17025 accredited Certificate. All our Rockwell Test Blocks meet the requirements of ASTM-E18 available with GRID etching.
