GB/T 7759.1-2015 Rubber,vulcanized or thermoplastic—Determination of compression set—Part 1:At ambient or elevated temperatures
Abstract
This part of GB/T 7759 specifies the test method for determining the compression permanent deformation performance of vulcanized rubber or thermoplastic rubber under normal and high temperature conditions. This method is used to measure the ability of rubber with a hardness range of 10 IRHD to 95 IRHD to maintain its elasticity after continuous compression under specified temperature and compression ratio (usually 25%) conditions. When the rubber hardness is greater than 80 IRHD, a lower compression ratio should be selected: 80 IRHD to 89 IRHD with a compression ratio of 15%, and 90 IRHD to 95 IRHD with a compression ratio of 10%.
