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. It is theresponsibility of the user of this standard to establish appro-priate safety and health practic

Significance and Use3.1 IRMs are vitally important in product and specificationtesting, in research and development work, in technical servicework, and in quality control operations in the rubber andcarbon black industries. They are especially valuable forreferee purposes. Ma
23、ny ASTM rubber standards for the evalu-ation of natural or synthetic rubber require the use of specificIRMs in their test recipes for better laboratory repeatability andreproducibility.3.2 New material lots that have been selected as candidatesfor IRM approval shall conform to the appropriate specif
24、ica-tions given in this standard and meet requirements given inPractice D4678 before the lots may be accepted as IRMs.3.3 The chemical and physical IRM specifications shownwill ensure some consistency in IRM properties from one lot tothe next. However, the specifications cannot ensure exactinter-lot
