Hardness SHORE

Hardness tester Shore

Shore durometer are based on international standards for the hardness measurement of rubber, plastics and other non-metallic materials (ISO, ASTM, DIN, BS, NFT etc.).
Hardness is the resistance against the indentation of a known geometrical indentor with determined force into a sample. The indentation depth is measured and displayed analogically or digitally.

The indentor is 2.5 mm away from the contact surface at zero durometer reading. Therefore you can only measure samples with a thickness of 6 mm or more (durometer A) or you can stack 3 samples with 2 mm thickness each to 6 mm total.
If the samples are thinner than the recommended thickness you are measuring the hardness of the underlying surface (support table or workbench). This will give a false reading due to the "anvil effect".

Creep: if the durometer is maintained with constant pressure on the sample, the specified hardness will decrease with time: the penetrator tends to continue to penetrate into the material. This phenomenon called creep varies from material to another, but requires more rigour to the extent that it is important: measurement of the hardness after a well-defined time after the application of the load interval, maximum indicator...
