Developed by Subcommittee: D20.22
WITHDRAWN, NO REPLACEMENT
This standard, including test methods, applied to flexible cellular rubber products known as latex foam rubbers but did not apply to sponge and expanded rubbers. The base material used in their manufacture shall be natural rubber, reclaimed rubber, synthetic rubber, alone or in combination.
Formerly under the jurisdiction of Committee D20 on Plastics, this standard was withdrawn in April 2014. This standard is being withdrawn without replacement due to its limited use by industry.
1.1 These specifications, including test methods, apply to flexible cellular rubber products known as latex foam rubbers but do not apply to sponge and expanded rubbers. The base material used in their manufacture shall be natural rubber, reclaimed rubber, synthetic rubber, alone or in combination.
1.2 In case of conflict between the provisions of these general specifications and those of detailed specifications or test methods for a particular product, the latter shall take precedence. Reference to methods for testing cellular rubber products should specifically state the particular test or tests desired.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.4 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—There is no known ISO equivalent to this standard.
