Abstract

This specification establishes requirements for chemically blown cellular rubber. Cellular rubber may be classified into two types: Type I which is open cell or sponge rubber and Type II which is closed cell or expanded rubber. Both types are divided into three grades: Grade A which is oil-and flame-resistant, Grade B which has no requirements for oil ,flame resistance, or low temperature, and Grade C which is low-temperature resistant. Each type and class has been divided into three different conditions. Each condition is based on a specific range of firmness as expressed by compression deflection as follows: super soft, soft, soft-medium, medium, medium-firm, and firm conditions. Several tests shall be performed in order to determine the following physical properties of cellular rubber: compression deflection, low-temperature resistance, accelerated aging, recovery, flame resistance, shrinkage, water absorption, oil aging, and color.

1. Scope

1.1 This specification establishes requirements for chemically blown cellular rubber.

1.2 In the case of conflict between the provisions of this specification and those of detailed specifications or test methods for a particular product, the latter shall take precedence.

1.3 Unless specifically stated otherwise, by agreement between the purchaser and the supplier, all test methods shall be performed in accordance with the test methods specified in this specification.

1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

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.

1.5 There is no known ISO equivalent to this specification.

This specification was revised using the updated test methods and specifications in Specification D 1056 - 07.
