Hardness test method
- Use a test mold with a flat test surface accompanied with an opposing surface which is also flat and parallel to the test surface.
- Hold the tester securely by hand and lower it vertically at a constant speed pressing it on the mold surface. The maximum value is read immediately after the contact. Measurement made askew or upward or on a vertical surface may lead to erroneous results.
