These specifications cover vulcanized elastomer compounds of natural rubber, reclaimed rubber, synthetic rubber, or rubberlike materials, alone or in combination, which are intended for use in manufacturing products for automotive applications. Compounds for tires, inner tubes, sponge rubber, hard rubber, belts, hose, mats, and insulated wire and cable are not included. The compounds listed in Tables 1 to 6 are of three types grouped in six classifications, based primarily on physical properties, which are prescribed in the tables. These values together with any additional requirements indicated by suffix letters in the grade designations as described in section, Types, Classes, and Grades of Compounds, define the properties of the compounds after vulcanization.
