This standard specifies the classification and marking, requirements, test methods, inspection rules, signs, packaging, transportation and storage of oil-resistant asbestos rubber sheets. This standard is applicable to all kinds of plates used to manufacture oil-resistant sealing gaskets formed by rolling with chrysotile as reinforcing fiber and oil-resistant rubber as adhesive. The sealing gasket made of this plate can also be used as a reference.
