Plastics and ebonite — Determination of indentation hardness by means of a durometer (Shore hardness)

Specification of a method for the determination of the indentation hardness by means of two types of durometers: Type A for softer materials and type B for harder materials. The method permits measurement either of the initial indentation or of the indentation after a specified time of recovery. This method is an empirical test and primarily intended for control purposes.
