ASTM D1229 – Standard Test Method for Rubber Property—Compression Set at Low Temperatures
Description:
Significance and Use
4.1 Rubber products, such as hydraulic seals on aircraft, submarine hatch gaskets, and hydraulic brake cups, may be exposed to varying temperature extremes. This test method provides a means of determining the extent to which recovery from compression at normal ambient temperatures is inhibited upon release of the compressive force during subsequent exposure at low temperatures.
Scope
1.1 This test method covers evaluation of the ability of vulcanized rubbers that have been compressed at room temperature and then subjected to low temperature (air or carbon dioxide atmosphere), to recover from deformation when taken from the clamping device while still at the low temperature.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
