It is the responsibility of the d124 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. There is no known ISO equivalent to this standard.
Any other size two-roll laboratory mill may be used provided the charge is adequate to maintain a uniform rolling bank on the rolls and to furnish sufficient material for test specimens.
Referenced Documents purchase separately The documents listed below are referenced within the d148 standard but are not provided dd1248 part of the standard. Irradiance at the control point shall be maintained at 0.
This standard does not purport to address all of the safety concerns, if any, associated with its use.
Last previous edition approved in as D – 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 characteristics covered too broadly or not at all by the type, class, and category designations. Prepare the specimens in accordance with Methods D for physical tests of insulations and jackets. For all materials to be conditioned for electrical testing, conditioning shall comply with the requirements of the standard test methods for electrical testing.
Category 1,Category 2, Category 3,Category 4, and Category 5.

These specimens are compression molded thermoplastic specimens. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Materials and Manufacture 6. Current edition approved March 1, Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Make duplicate determinations from a sample of the material in the form of powder, granules, or pellets. NOTE 2—This standard sstm undergone major revision from the reapproval of and now covers only polyethylene for wire and cable applications.

No conditioning is required. If necessary, level of contamination may be agreed upon between the seller and the purchaser.
Solution viscosity is recommended as a means of distinguishing such materials. The degree of departure from Newtonian behavior depends on the nature and molecular constitution of the individual sample. However, the non-irradiance control machine can still be used for relative weatherability comparison among different materials weathered at the same time. Make duplicate determinations on the material in the form of powder, granules, or pellets.
Renumbered all subsequent sections accordingly. D — 05 G Dissipation factor and dielectric constant must not exceed the limits speci? For information regarding molding and extrusion materials, see Specification D The tests involved in this specification are intended to provide information for identifying materials according to the types, classes, categories, and grades covered.
The following additional instructions and the precautions of Note 12 shall be observed: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. The polyethylene plastics are identified primarily on the basis of two characteristics, namely, density and flow rate previously identified as melt index.
