Covers flexible cellular rubber products known as sponge rubber and expanded rubber, but does not apply to latex foam rubber or ebonite cellular rubber. The base material for an open/closed cellular product may be made of synthetic, natural, reclaimed rubber, or a mixture, and may contain other polymers or chemicals, or both, which may be modified by organic or inorganic additives.

Except as otherwise specified in these methods, the following ASTM test methods and the various test methods in Table 3, applicable in general to vulcanized rubber, shall be complied with as required and are hereby made a part of these methods:
