This specification covers the chemical and physical quality specifications or requirements, or both, for Industry Reference Materials (IRMs) as cited in a certain practice and other standards. IRMs as evaluated and referenced in the said certain practice are vitally important to conduct product, specification and development testing in the rubber and carbon black industries. IRMs are vitally important in product and specification testing, in research and development work, in technical service work, and in quality control operations in the rubber and carbon black industries. They are especially valuable for referee purposes. Many ASTM rubber standards for the evaluation of natural or synthetic rubber require the use of specific IRMs in their test recipes for better laboratory repeatability and reproducibility. Some of the chemicals or materials specified include tetramethyl thiuram disulfide, benzothiazyl disulfide, N-tert-butyl-benzothiazole sulfenamide, stearic acid, sulfur, naphthenic process oil, zinc oxide, butyl rubber, petroleum oil, ammoniated latex antigenic protein, and rabbit anti AL antisera.
