This test measures the depth of indentation of a ball into a sample. Hardness values are then calculated using tables derived from the empirical relationship between indentation depth and hardness.
Smithers Rapra can offer a comprehensive range of hardness measurements. Low, macro, high and micro machines are available. Shore A and D durometer determinations are also performed, with durometers mounted to a stand, yielding better reproducibility.
Our extensive sample preparation facilities mean we are able to test a huge variety of materials and product forms.
Standards and Accreditation
