Asm 6—Carbon black 35 nm or less in average particle diameter is used as required in black electrical and jacketing materials Grades E and J to impart maximum weather resistance. These specimens are compression molded thermoplastic specimens. Link to Active This link will always route to the current Active version of the standard. The degree of departure from Newtonian behavior depends on the nature and molecular constitution of the individual sample.

For routine inspection, only those tests necessary to identify the material to the satisfaction of the purchaser shall be required. Category 1,Category 2, Category 3,Category 4, and Category 5. For information regarding molding and extrusion materials, see Specification D Basis of Purchase 5. Materials and Manufacture 6. Work Item s – proposed revisions of this standard. Packaging and Package Marking Specimens shall be either die cut or machined to the speci?

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

The following additional instructions and the precautions of Note 12 shall be observed: The extrusion material for wire and cable shall be polyethylene plastic in the form of powder, granules, or pellets.

In the absence of contrary requirements, the following values shall apply: Your comments are invited either for revision of this standard wstm for additional standards and should be addressed to ASTM International Headquarters. Sampling for inspection and testing shall be carried out in accordance with the recommendations of Practice D If necessary, level of contamination may be agreed upon between the seller and the purchaser.


ASTM D is a specification for identification of polyethylene plastics extrusion materials for wire and cable. Asm a question about conducting the test for this standard? March 1, 1 2 3 4 5 S1248 a new Section Test specimens over 7 mm in thickness shall be conditioned for 88 h.

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

Based on published information, the nominal values for the? For information regarding plastic pipe materials, see Specification D We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

J5 22 [] —75 The exposure cycle consists of a light cycle of 10 h with 18 minutes water spray on the front surface during each 2 h period followed adtm a dark period of 2 h with continuous water spray on the back surface. Identification is to be done based ast types, classes, categories, and grades. Warning—The expected service lifetime of Class D materials is very dependent upon the speci?

The molded specimen thickness shall be 1. NOTE 15—Longer periods of exposure will be required for older xenon-arc machines operated at irradiance of 0. This abstract is a brief summary of the referenced standard. However, no information is available on the relation between exposure times and service life under use conditions for wire and cable. Make duplicate determinations using two separate portions of the same molding or from two moldings.

It is not the function of this d128

A number in parentheses indicates the year of last reapproval. The initial distance between the bench marks or extensometer grips shall 6 be The tests involved in this specification are intended to provide information for identifying materials according to the types, classes, asm, and grades covered.


Make duplicate determinations on the material in the form of powder, granules, or pellets. Link to Active This link will always route to the current Active version of the standard. NOTE 2—This standard has undergone major revision from the reapproval of and now covers only polyethylene for wire and cable applications.

For such materials, the milling procedure described in Current edition approved March 1, We are confident that we have what you are looking for. Prepare the specimens in accordance with Test Methods D for physical tests of insulation and jackets. Make duplicate determinations from a sample of the material in the form of powder, granules, or pellets.

By means of our testing expertise and modular product design, we will help find the solution that is right for you.

For all asrm to be tested for electrical properties, the laboratory shall comply with the requirements of the standard test methods for electrical testing.

To illustrate the manner in which the maximum limit for the dielectric constant of a particular, grade is determined, assume that a Type I, Class A material is to be supplied under Grade E2, then its maximum limit for dielectric constant will be 2.

E2 10 [] — NOTE 8—Tables 4 and 5, are included to correspond with the grades 1d248 See Guide D and 3. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
