22、ations and methodsof test3. 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
23、. Many 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 sp
