4.1 This test method may be used for research and development. It also may be used for quality assurance, provided a standard has been agreed upon between a producer and a user.

4.2 For identification purposes, melting range should be supplemented by measurements of a more specific physical and chemical property.

4.3 This test method is not recommended for rubber chemicals that decompose at their melting ranges.

4.4 The melting range as determined by Test Method A—Capillary Tube Melting Range is not recommended as a criterion of purity of a rubber chemical.

1.1 These test methods cover the determination of the melting range of commercial rubber processing chemicals either by use of capillary melting point tubes or by differential scanning calorimetry (DSC).

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.

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.
