ASTM D4568-99
(Test Method)Standard Test Methods for Evaluating Compatibility Between Cable Filling And Flooding Compounds And Polyolefin Wire and Cable Materials
Standard Test Methods for Evaluating Compatibility Between Cable Filling And Flooding Compounds And Polyolefin Wire and Cable Materials
SCOPE
1.1 These test methods evaluate the compatibility between cable filling or cable flooding compounds, or both, and polyolefin materials used in the manufacture of wire and cable that are usually in intimate contact with the filler or floodant, or both.
1.2 These test methods are useful to ensure compatibility and to verify that new formulations of filling or flooding compounds will have no deleterious effect upon the other polyolefin materials being used or, conversely, use these methods to ensure that other polyolefin wire and cable materials are evaluated for possible use not degraded by contact with fillers or floodants already in use.
1.3 The values stated in inch-pound units are regarded as the standard. SI units are for information only.
1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
