1、Designation:D456813Standard Test Methods forEvaluating Compatibility Between Cable Filling andFlooding Compounds And Polyolefin Wire and CableMaterials1This standard is issued under the fixed designation D4568;the number immediately following the designation indicates the year oforiginal adoption or

2、,in the case of revision,the year 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.Scope*1.1 These test methods evaluate the compatibility betweencable filling or cable flooding

3、compounds,or both,andpolyolefin materials used in the manufacture of wire and cablethat are usually in intimate contact with the filler or floodant,orboth.1.2 These test methods are useful to ensure compatibilityand to verify that new formulations of filling or floodingcompounds will have no deleter
