1、Designation: D5900 15aD5900 15bStandard Specification forPhysical and Chemical Properties of Industry ReferenceMaterials (IRM)1This standard is issued under the fixed designation D5900; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisio
2、n, 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, fo
3、r 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
4、be 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 stat
5、ed in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety a
6、nd health practices and determine the applicability of regulatorylimitations prior to use.2.
