25、icance 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 for
26、 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 stand
27、ard 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. Assignment
