The Shore Durometer is one of the modern non-destructive testing instruments for measuring of the hardness value of different materials at the workshops and laboratories. This device can be used at the radio instruments industry, mechanical engineering and other areas of modern industry.
Shore Durometer NOVOTEST TS-A complies to: ISO-7619 and ISO-868, DIN53505, ASTM D2240 and JIS K7215.
Soft plastic, printed circuit boards, glass, elastomers, fibers, soft rubber, leather, resin, wax, neoprin, butyl, silicone, vinyl are typical testing materials for Shore Durometer. The principle of determining the hardness value of materials is based on the calculation the value of material’s resistance to the penetration of the indenter with a preset load.
Wide range of applications and materials
Shore Durometer NOVOTEST TS-A applies for measurements by Scale A (Shore A) and D (Shore D). This makes it applicable to a wide range of elastomers and polymers.
Here are some examples of materials which hardness is tested by Shore A scale:
- Soft rubber, elastomers, silicone, neoprin, vinyl, butyl, nitrile, soft plastics, leather, wax, etc.
- Rubber bands
- Can tester pads
- Rubber stamps
- Pencil erasers
- Screen wiper blades
- Automotive tires
- Shoe heels
- Abrasive handling pads
- Shoe soles
- Tap washers
- Typewriter rollers
- Forklift solid tires
The Shore D scale is used for harder rubbers and plastics. There is a crossover between the A and D scale, with materials softer than 50D (approximately equivalent to 95A) expressed using the A scale. Any material harder than this follows the Shore D scale. Materials harder than 65D usually feel completely rigid and do not have the flexibility and surface flex. At the top end of the Shore D scale, a transition is made to the Rockwell scale where materials such as nylons and acetals are found. Harder materials offer a much greater resistance to flex making them an ideal choice for applications such as impact protection and metal replacement. Applications include mechanical products such as gear wheels and cogs, and castors and wheels.
The typical applications of Shore hardness testing by Scale D:
- Rubber, resin, glass, PCB, fibers, plastics, etc.
- Golf ball, metal forming wiper dies, paper-making rolls
