1.1 This International Standard specifies a method for the determination of the indentation hardness of plastics and
ebonite by means of durometers of two types: type A is used for softer materials and type D for harder materials (see
the Note to 8.2). 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.
1.2 This method is an empirical method intended primarily for control purposes. No simple relationship exists
between indentation hardness determined by this method and any fundamental property of the material tested. For
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.
