1.1 This specification covers flexible cellular rubber products known as sponge rubbers and expanded rubbers but does not apply to latex foam rubbers. The base material used in their manufacture may be natural rubber, reclaimed rubber, synthetic rubber or rubber-like materials, alone or in combination. Ebonite cellular rubbers are not included.

1.2 Extruded or molded shapes of sizes too small for cutting standard test specimens are difficult to classify or test by these methods and will usually require special testing procedures.

1.3 In case of conflict between the provisions of this general specification and those of detailed specifications or methods of test for a particular product the latter shall take precedence. Reference to these methods for testing cellular rubber products should specifically state the particular test or tests desired.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 The following safety hazards caveat pertains only to the test methods sections of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
