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 – 13 Determinations and Report for the General Method 14 and 15 Density 16 Extract Analysis 17 – 26 Sulfur Analysis 27.1 – 33 Fillers Analysis 34 – 40 Ash Analysis 41 – 51 Part B. Determination of Rubber Polymers 52 – 58 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary or warning 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 , 54.6 , 56.5.3 , and 57.7.3 ; and X1.3.3 and X2.4.1.6 . 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
