1.1 This classification is intended to establish a method to find compounding materials on a computer data base by both functional and chemical classification. This classification will include rubber compounding materials or ingredients normally used in formulating rubber compounds. This classification is not intended for use in rubber latex or solvent based rubber adhesive applications.

1.2 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.

1.3 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.

3.1 Commercially available computer material management programs are being used regularly in the rubber industry. These programs typically will retrieve information from a raw material or compounding material data base by chemical name, CAS registry number, trade name, and supplier name. Retrieving information by these fields can present problems. The common chemical names are not standardized. IUPAC nomenclature is standardized but the names typically are too lengthy for easy retrieval. Also, the user may not have information such as trade name, supplier name, or CAS registry number.

3.2 An alternate method of retrieving information from a raw material or compounding material data base is to sort by classification. This has the added advantage of enabling a compounder to select a compounding material from a given classification for a new compound formulation.
