1、Designation: D7850 13D7850 18Standard Specification forBiological Properties of Industry Reference Materials (IRM)1This standard is issued under the fixed designation D7850; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、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 biological quality specifications or requirements, or both, for Industry Reference Ma
3、terials(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 be accepted as an IRM,
4、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 a biological IRM.1.4 The values stated in SI unit
5、s 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 safety, health
6、, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of Internat

9、Proteins (Hev b 1, 3, 5 and 6.02) in HeveaNatural Rubber and Its Products Derived from Latex3. Significance 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 carb
10、on black industries. They are especially valuable for referee purposes. ManyASTM rubber standards for the evaluation of natural or synthetic rubber require the use of specific IRMs for better laboratoryrepeatability and reproducibility.3.2 New material lots that have been selected as candidates for
11、IRM approval shall conform to the appropriate specificationsgiven in this standard and meet requirements given in Practice D4678 before the lots may be accepted as IRMs.3.3 The biological IRM specifications shown will ensure some consistency in IRM properties from one lot to the next. However,the sp
12、ecifications cannot ensure exact inter-lot consistency.1 This test method specification is under the jurisdiction of ASTM Committee D11 on Rubber and Rubber-like Materials and is the direct responsibility of SubcommitteeD11.40 on Consumer Rubber Products.Current edition approved Jan. 1, 2013June 1,
