Standard Specifications for Flexible Cellular Materials-Latex Foam (Withdrawn 2014)
ABSTRACT
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. The structure of latex foam rubbers consists of a network of open or interconnecting cells. Latex foam rubbers are made from rubber latices or liquid rubbers. They are manufactured in sheet, strip, molded, or specific shapes. Latex foam rubbers shall have a vulcanized cellular structure with a porous surface. The cells shall be interconnecting and of a uniform character. Latex foam rubbers shall be either cored or solid. Latex foam rubbers shall have their grade numbers designated by two letters which identify the kind of latex foam rubber as follows: RC for latex foam rubbers cored and RU for latex foam rubbers uncored. Digits following the letters are used to indicate the degree of firmness, the softer grades being identified with the lower numbers and the firmer grades with the higher numbers. These rubbers shall be subjected to the following tests: accelerated aging test, compression set under constant deflection test, flexing test, low temperature test, and static fatigue test.
SCOPE
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.
WITHDRAWN RATIONALE
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.
