The method permits measurement either of the initial indentation or of the indentation after a specified period of time, or both. NOTE The durometers and the methods specified in this International Standard are referred to as type A Shore and type D Shore durometers and durometer methods, respectively. specification purposes, it is recommended that IsO 48, Rubber, vulcanized or thermoplastic - Determination of hardness (hardness between 10 IRHD and 100 IRHD), be used for the softer materials. 2 Normative reference The following normative document contains provisions which, through reference in this t
