However, because this test is lengthy, it need not be performed on every lot of material. Renumbered all subsequent sections accordingly.

By means of our testing expertise and modular product design, we will help find the solution that is right for you. For information regarding plastic pipe materials, see Specification D Warning—The expected service lifetime of Class D materials is very dependent upon the astk F Dielectric constant is a function of density; hence, the nominal value will be different for each type.

Perform the tests in accordance with Practices GGand D using the following exposure conditions: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This standard is subject to revision at any time by the responsible technical committee and must be dd1248 every?

The tests involved in this specification are intended to provide information for identifying materials according to the types, classes, categories, and grades covered. In the absence of contrary requirements, the following values shall apply: Link to Active This link will always route to the current Active version of the standard. No conditioning is required. For such materials, the milling procedure described in The letters associated with these grades identify areas of potential applicability as indicated below: Give our test engineers a call today for help configuring the best test machine and accessories according to your standard.

ASTM D1248 Polyethylene Plastics Extrusion for Wire and Cable | Test Equipment

However, no information is available on the relation between r1248 times and service life under use conditions for wire and cable. This is discussed in Asrm D It is not the function of this specification to provide specific engineering data for design purposes. Based on published information, the nominal values for the?

Contact your supplier for additional information regarding this issue. A number in parentheses indicates the year of last reapproval. Additional characterization of the sample can be obtained if other conditions are used.

Selection of acceptable quality level AQL and of inspection level IL shall be made, with consideration of the speci? Bench marks or a high range d248 shall be used for the determination of elongation at break. Packaging and Package Marking E3 10 [] — Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

The extrusion materials for wire and cable shall be as uniform in composition and size and as free of contamination as can be achieved by good manufacturing practice. J3 12 [] —75 Test results for specimens that break outside the gage-marks after extensive cold drawing need not be discarded unless the break occurs between the contact surfaces of a grip.

For information regarding plastic pipe materials, see Specification D J5 22 [] —75 For routine inspection, only those tests necessary to identify the material to the satisfaction of the purchaser shall be required.

NOTE 12—If it is known or suspected that the material contains moisture, the sample should be dried prior to being tested, but otherwise no conditioning is required. NOTE 16—The irradiance level in the unit that does not have irradiance control is reported to be 0.

NOTE 2—This standard has undergone major revision from the reapproval of and now covers only polyethylene for wire and cable applications. This specification provides for the identification of polyethylene plastics extrusion materials for wire and cable in c1248 a manner that the seller and the purchaser can agree on the acceptability of aetm commercial lots or shipments. The polyethylene plastics are identified primarily on the basis of two characteristics, namely, density and flow rate previously identified as melt index.

ASTM D Polyethylene Plastics Extrusion for Wire and Cable | Test Equipment

Originally approved in ASTM D refers to a number of ASTM mechanical testing standards to determine physical characteristics of polyethylene plastic extrusion wire and cable. For all materials to be conditioned for asm testing, conditioning shall comply with the requirements of the standard asfm methods for electrical testing.

Specimens shall be either die cut or machined to the speci? Note 2—This standard has undergone major revision from the reapproval of and satm covers only polyethylene for wire and cable applications.

Other attributes important for certain applications are covered by three general classes and by specifying in greater detail, by grades, a minimum number of key d12248 covered too broadly or not at all by the type, class, and category designations. E4 12 [] —75 It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Make duplicate determinations on the material in the form of powder, granules, or pellets. 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.
