NOTE 14—The h exposure period speci? The initial distance between the bench marks or extensometer grips shall 6 be There is no known ISO equivalent to this standard. NOTE 2—This standard has undergone major revision from the reapproval of and now covers only polyethylene for wire and cable applications. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Contact your supplier for additional information regarding this issue. ASTM D is a specification for identification of polyethylene plastics extrusion materials for wire and cable. Additional characterization of the sample can be obtained if other conditions are used. The tests involved in this specification are intended to provide information for identifying materials according to the types, classes, categories, and grades covered. A Samples shall be drawn from the required number of units, and pooled for preparation of molded samples for mechanical properties evaluation.

Last previous edition approved in as D – Materials and Manufacture 6. For all materials to be tested for electrical properties, the laboratory shall comply with the requirements of the standard test methods for electrical testing. Irradiance at the control point shall be maintained at 0.

Note 3—See Guide D and 3. No conditioning is required. E5 12 [] —75 Changed the title of paragraph This is discussed in Practice D In all cases the laboratory shall report both the temperature and humidity conditions during testing. The degree of departure from Newtonian behavior depends on the nature and molecular constitution of the individual sample.

The initial grip separation shall be Rather, the material is to be checked aatm for compliance with this requirement and, after that, as often as necessary to assure continued compliance.
