ASTM D395-B
Standard Test Methods for Rubber Property—Compression Set


ASTM D395-B establishes procedures for measuring the compression set of elastomers and plastics, quantifying permanent deformation after exposure to controlled compressive stress and temperature conditions. This method employs a standardized 1-inch diameter indenter with defined measurement intervals, typically extending to 22 hours, to assess elastic recovery. Applicable to natural and synthetic rubbers, thermoplastic elastomers, and various plastics, the test evaluates material resilience and dimensional stability under prolonged mechanical loading, ensuring adequate performance in demanding applications where resistance to permanent set is critical.
