1、Designation: D7850 13Standard 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 of last
2、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 specifi-cations or requirements, or both, for Industry ReferenceMaterials
3、(IRMs) as cited in Practice D4678 and other stan-dards.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,it must
4、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 a biological IRM.1.4 The values stated in SI units are to b
5、e 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 practices and d

8、m Latex3. 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. Many ASTM rubber
9、 standards for the evalu-ation of natural or synthetic rubber require the use of specificIRMs for better laboratory repeatability and reproducibility.3.2 New material lots that have been selected as candidatesfor IRM approval shall conform to the appropriate specifica-tions given in this standard an
10、d meet requirements given inPractice D4678 before the lots may be accepted as IRMs.3.3 The biological IRM specifications shown will ensuresome consistency in IRM properties from one lot to the next.However, the specifications cannot ensure exact inter-lot con-sistency.4.
