SHORE AND IRHD HARDNESS TESTS

What are the Shore and the IRHD hardness tests and how do they work?

SHORE
(ISO 7619 / ASTM E2240)
Shore AASTM E2240
ISO 7619
Frustum 35°Soft surfaces, flexible rubber, natural rubber, plastic, PVC, polyester, neoprene, leather, nitrile rubbers, tires, etc
Shore DASTM E2240
ISO 7619
Cone 30°Hard and rigid surfaces, ceramic and composites, acrylics, plexiglass, print rolls, cellulose, acetates, nylon, etc
Shore BASTM E2240Cone 30°Medium values. As A scale for higher values.
Shore CASTM E2240Frustum 35°Medium-hard values. As D scale for lower values.
Shore DOASTM E2240Ball 1.2 mmFrom medium-hard to hard values. As B and C.
Shore OASTM E2240Ball 1.2 mmLow values and very flexible materials. As A scale for low values.
