Background information

Reference blocks, indenters and calibration

IS 1586 (Part 3) · IS 1500 (Part 3) · ISO 6508-3 · ISO 9513 · ASTM E83

A hardness reference block is a test piece whose hardness has been determined on a standardising machine and certified, together with its uniformity, according to IS 1586 (Part 3), IS 1500 (Part 3) or ISO 6508-3. Testing a block before each shift is the indirect verification that confirms a hardness tester, its indenter and its test force are still producing correct values.

Indenters are verified for geometry and surface finish: the 120° diamond cone with its 0.2 mm tip radius for Rockwell, tungsten carbide balls for Brinell and Rockwell B, and the 136° pyramid for Vickers. Testing tables, jack rests, step inserts and clamping devices hold the specimen rigidly so that table movement cannot affect the reading.

The ETS extension calibrator verifies the displacement measurement of extensometers and hardness-tester depth systems against ISO 9513 and ASTM E83 classes, and the thermal printers and PC reporting software complete the traceable record from test to certificate.
