Hardness test blocks give your tester a certified, traceable reference to verify accuracy and stay within tolerance. WESTport supplies blocks for every major hardness scale — Brinell, Rockwell, Rockwell superficial and microhardness — each individually calibrated in our ISO/IEC 17025 accredited laboratory.

  • Brinell test blocks across the full load range, 250 kg through 3000 kg.
  • Rockwell standard test blocks covering the A, B, C, D, E, F, G, H and K scales.
  • Rockwell superficial test blocks for the 15N, 30N, 45N, 15T, 30T and 45T scales.
  • Microhardness test blocks in Vickers and Knoop, mirror polished and precision mounted.
  • Rockwell master calibration sets pairing matched blocks with the indenter or penetrator used to certify them.

Every block is individually tested and ships with a certificate traceable to NIST. Test surfaces are hand lapped and diamond polished to a mirror finish, and recertification is available to keep your hardness testing system in control.
