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.
