The metal industries
work with various materials that are subject to special treatments,
leading to a specific hardness. E.g., engine blocks made from aluminium
typically hold a relatively low metal hardness often measured in Leeb
HL, Brinell HB or Rockwell HRB. In contrast, rollers used in steel
rolling hold a hardness that can easily exceed 800 HLD ~60 HRC ~750 HV.
In order to verify that the Equotip tester is
calibrated, the user is meant to conduct test impacts on a HL reference
test block that is close to the hardness of the sample.
Equotip test blocks are available in 4
hardness ranges, placing users in the unique position where they can
compare the readings of their instruments with the genuine HL
calibration value marked on the test block.
- Authority: Proceq’s Equotip is aligned with the Leeb scales of the major national institutes.
- Accuracy:
In accordance with the standards, the test blocks are calibrated using
the impact device type later used in the application – without any
conversion errors.
- Versatility: Equotip test blocks cover a greater hardness range than any other manufacturers’ Leeb blocks.
- Price / performance: Verifying instruments on test blocks can prevent expensive product recalls.
