What is ISO 815-1 - Rubber, vulcanized or thermoplastic about ?
ISO 815-1 is the first part of the multi-series standard that specifies methods for the determination of the compression set characteristics of vulcanized and thermoplastic rubbers at ambient or elevated temperatures. The methods described in ISO 815-1 are intended to measure rubbers’ hardness within the range of 10 IRHD to 95 IRHD to retain their elastic properties at specified temperatures after prolonged compression at constant strain (normally 25 %) under one of the alternative sets of conditions described. Note 1: When rubber is held under compression, physical or chemical changes that prevent the rubber from returning to its original dimensions after the release of the deforming force can occur. The result is a set, the magnitude of which depends on the time and temperature of compression as well as on the time, temperature, and condit...
