Subscription pricing is determined by: Readings on one material may be satisfactory for such a table, but there is no guarantee that other plastic materials will give corresponding readings because of differences in elasticity, creep, and shear characteristics. Generally, an uncured specimen has a hardness reading below normal. In practice, the Rockwell hardness number is derived from the following relationship:.

If there are no material specifications, then the default conditions apply. Rockwell hardness numbers are always quoted with a scale symbol representing the indenter size, load, and dial scale used. Before proceeding with this test method, reference should be made to the specification of the material being tested.
