2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the chemical and physical quality specifications or requirements, or both, for
3、 Industry ReferenceMaterials (IRMs) as cited in Practice D4678 and other standards.1.2 IRMs, as evaluated and referenced in Practice D4678, are vitally important to conduct product, specification, anddevelopment testing in the rubber and carbon black industries.1.3 Before a new lot of material can b
4、e accepted as an IRM, it must comply with the specifications prescribed in thisspecification. However, these specifications are only part of the requirements. Other requirements as given in Practice D4678 shallbe met before a candidate material can be formally accepted as an IRM.1.4 The values state
