Defines a procedure for determining the indentation hardness of plastics and ebonite using durometers of two types - A for softer materials and D for harder materials. Allows for measuring either of the initial indentation or of the indentation after a defined period of time, or both.

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: typeA is used for softer materials and typeD 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 typeA Shore and typeD 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 ISO48, Rubber, vulcanized or thermoplastic — Determination of hardness (hardness between 10 IRHD and 100 IRHD), be used for the softer materials.
