Title
Standard Specification for Flexible Cellular Materials - Sponge or Expanded Rubber
ASTM International
Publication Date:
Mar 1, 2007
Scope:
This specification 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,
or reclaimed rubber, or a mixture, and may contain other polymers
or chemicals, or both, which may be modified by organic or
inorganic additives. These elastomeric materials have properties
similar to those of vulcanized rubber, namely (1) the ability to be
converted from a thermoplastic to a thermosetting state by
crosslinking (vulcanization) or (2) the substantial recovery of
their original shapes when strained or elongated, or both.
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.
In case of conflict between the provisions of this general
specification and those of detailed specifications or test methods
for a particular product, the latter shall take precedence.
Reference to the test methods in this specification should
specifically state the particular test or tests desired.
The values stated in SI units are to be regarded as the
standard.
The following safety hazards caveat pertains only to the test
methods portions of this specification: This standard does not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
NOTE 1—ISO 6916-1 is similar to this specification.
*A Summary of Changes section appears at the end of this
standard.
