Scope1.1 This specification covers the chemical and physicalquality specifications or requirements, or both, for Industry
3、Reference Materials (IRMs) as cited in Practice D4678 andother 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 be accepted
4、as an IRM,it must comply with the specifications prescribed in thisspecification. However, these specifications are only part of therequirements. Other requirements as given in Practice D4678shall be met before a candidate material can be formallyaccepted as an IRM.1.4 The values stated in SI units
5、are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use.
