Rockwell Hardness Test Blocks

Gilmore Rockwell Hardness Test Blocks (also known as Rockwell Test Coupons) are manufactured and calibrated to current ASTM E-18 and/or ISO 6508 specifications.

Grid patterns can be added to blocks to insure spacing requirements per ASTM E-18.

All Laboratory calibrations accredited ISO 17025.
