This standard is equivalent to the international standard ISO844-1978 "Compression Test of Foamed Plastic Rigid Materials". This standard is applicable to the determination of the compressive strength and relative deformation of rigid foamed plastics, or the compressive stress when the relative deformation is 10%.
