Description

1.1 These test methods cover the qualitative and quantitative analysis of the composition of rubber products of the ‘R’ family (see 3.1). Many of these test methods may be applied to the analysis of natural and synthetic crude rubbers.

1.1.1 Part A consists of general test methods for use in the determination of some or all of the major constituents of a rubber product.

1.1.2 Part B covers the determination of specific polymers present in a rubber product.

1.1.3 The test methods appear in the following order:

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

1.3 This standard does not purport to address all of the safety problems, 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. Specific precautionary statements are given in 31.4.5, 31.6, 37.4.2, 38.4.2, 45.1.3, 53.2.3.5, 54.4.2, and 56.5.3; and X1.3.3 and X2.4.1.6.
