1、Designation: D5900 15bD5900 15cStandard 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

24、nificance and Use3.1 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. ManyASTM rubber standards
25、for the evaluation of natural or synthetic rubber require the use of specific IRMs in their test recipes forbetter laboratory repeatability and reproducibility.3.2 New material lots that have been selected as candidates for IRM approval shall conform to the appropriate specificationsgiven in this st
26、andard and meet requirements given in Practice D4678 before the lots may be accepted as IRMs.3.3 The chemical and physical IRM specifications shown will ensure some consistency in IRM properties from one lot to thenext. However, the specifications cannot ensure exact inter-lot consistency.4. Assignm
