Scope
This standard specifies the classification and marking, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of asbestos rubber sheets. This standard applies to all types of sheets made from chrysotile as reinforcing fibers and rubber as a binder, which are rolled and pressed to produce heat- and pressure-resistant sealing gaskets. Sealing gaskets made from such sheets can also be referenced for use.
