1. Scope

1.1These 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.

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

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

1.1.3The 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

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

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

1.3This 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. 1.4This 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.
