Using the type-D test control shows if the hardness
tester will operate within a specified tolerance. These tests are used
in production as well as science, research and development. In the box
you will find 3 test samples. The tests are identified by a series of
numbers to ensure that they are not misidentified. The range of hardness
of type-D is 30 to 90. The tests serve as a reference check of the
optimal state of operation of the hardness tester.
- Dimensions: approx. 54 x 54 x 8mm (single sample).
- 3 pieces
- DIN 53505
The hardness tester must never be recalibrated during the control tests.
