This specification covers gaskets cut from sheet rubber that are intended for general gasket applications on water, air, and low-pressure steam. The rubber sheet gasket covered by this specification are not intended for use with oils and strong acids. Compounds furnished under this specification shall be manufactured from natural rubber, reclaimed rubber, synthetic rubber, or mixtures thereof, together with added compounding materials, and shall be suitably vulcanized. The material shall be red or black in color as specified and shall conform to the prescribed physical property requirements including hardness, tensile strength, elongation, change in tensile strength and elongation after air aging, and compression set. Hardness, tensile strength, compression set, and air-aging tests shall be performed.
