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:

Part A. General Test Methods: Sections Rubber Polymer Content by the Indirect Method 11 to 13 Determinations and Report for the General Method 14 and 15 Density 16 Extract Analysis 17 to 26 Sulfur Analysis 27 to 33 Fillers Analysis 34 to 40 Ash Analysis 41 to 51 Part B. Determination of Rubber Polymers 52 to 58
