IS 3400 : Part 10 : 1977 : Methods of Test for Vulcanized Rubbers - Part X : Compression Set at Constant Strain

1. Scope

1.1 This standard ( Part X > prescribes a method of test for determining the compression set characteristics of vulcantied rubbers of hardness within the range of 30 to 95 IRHD*, at constant strain under one of the alternative sets of conditions prescribed ( see 6.1 and 6.2 ). With rubbers, especially those above 95 IRHD*, it may not be possibzy: achieve 25 percent compression strain. For such rubbers this method does not apply.
