1、Designation:D151415Standard Test Method forCarbon BlackSieve Residue1This standard is issued under the fixed designation D1514;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicate
2、s the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the waterwash sieve residue in regular untreated carbon blacks.It maynot be applicable to oil-treated carbon blacks because
3、the oilwould prevent proper wetting of the black by water.1.2 The values stated in SI units are to be regarded as thestandard.The values in parentheses are for information only.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibil
4、ity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specificprecautionary statements,see Section 6.2.Referenced Documents2.1 ASTM Standards:2D1799 Practice for Carbon BlackSampling Packaged
