Understanding Shore D vs Other Hardness Scales

Hardness scales are used to measure a material’s resistance to indentation. The most appropriate scale depends on the material being tested and its hardness range.

Shore A vs Shore D

The Shore A and Shore D scales are the most common durometer scales for elastomers and plastics.

Scale	Typical Materials	Hardness Range
Shore A	Soft rubbers, elastomers, silicones, neoprene	Soft to medium-hard
Shore D	Hard rubber, rigid plastics, thermoplastics	Medium-hard to very hard

Examples:

Rubber bands, soft seals, and flexible gaskets are typically measured using Shore A.
Hard hats, PVC pipe, nylon components, and rigid polyurethane are often measured using Shore D.

As a general guide:

A material measuring 95 Shore A may be better evaluated using Shore D because it has become too hard for the Shore A scale to provide sufficient resolution.
Shore D is designed with a sharper indenter and stronger spring force to measure harder materials accurately.

Choose Shore D when testing:

Rigid plastics
Hard rubber compounds
Thermoplastics
Polycarbonate
Acrylic materials
Nylon components
Hard polyurethane

For softer materials such as seals, flexible rubber, and silicone products, Shore A is usually the preferred scale.

Using Shore D Comparison Blocks

Shore D comparison blocks are primarily used to:

Verify durometer performance
Check instrument consistency
Train operators
Compare readings before testing production samples

A reading close to the certified value of the comparison block indicates that the durometer is functioning correctly and producing consistent results.
