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 A | ASTM E2240 ISO 7619 | Frustum 35° | Soft surfaces, flexible rubber, natural rubber, plastic, PVC, polyester, neoprene, leather, nitrile rubbers, tires, etc |
| Shore D | ASTM E2240 ISO 7619 | Cone 30° | Hard and rigid surfaces, ceramic and composites, acrylics, plexiglass, print rolls, cellulose, acetates, nylon, etc |
| Shore B | ASTM E2240 | Cone 30° | Medium values. As A scale for higher values. |
| Shore C | ASTM E2240 | Frustum 35° | Medium-hard values. As D scale for lower values. |
| Shore DO | ASTM E2240 | Ball 1.2 mm | From medium-hard to hard values. As B and C. |
| Shore O | ASTM E2240 | Ball 1.2 mm | Low values and very flexible materials. As A scale for low values. |
| Shore OO | ASTM E2240 | Ball 1.2 mm | Very soft rubbers, sponges, expanded rubber, foam rubber, natural rubber and silicon |
| Shore E | ASTM E2240 | Ball 2.5 mm | Very soft rubbers, natural rubber, elastomers, casting resin, soft PVC, leather, etc. |
| Shore M | ASTM E2240 | Cone 30° | As A scale, for thin specimens and elastomer materials. |
| Shore 000 | ASTM E2240 | Ball 6.35 mm | Ultra-soft rubbers, sponges, expanded rubber, foam rubber, natural rubber and silicon. |
