Plastics and Ebonite - Determination of Indentation Hardness by Means of a Durometer (Shore Hardness) - Third Edition
N 868
Annotation
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.
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.

Пластмассы и эбонит - определение твердости углубления посредством Durometer (береговая твердость) - третий выпуск
Этот Международный стандарт определяет метод для определения твердости углубления пластмасс и эбонита посредством durometers двух типов: тип A используется для более мягких материалов и типа D для более твердых материалов (см. Примечание к 8.2). Метод разрешает измерение или начального углубления или углубления после установленного периода времени или обоих.
