Omfang

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: durometer type A is used for softer materials and durometer type D for harder materials (see the note in 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 test intended primarily for control purposes. No simple relationship exists between indentation hardness determined by this method of any fundamental property of the material tested. For specification purposes, it is recommended that ISO 48, Vulcainzed rubbers - Determination of hardness (hardness between 30 and 85 IRHD), should be used for the softer materials.
