Standard Specification for Crosslinkable Ethylene Plastics
1.1 This specification covers a general classification system for crosslinkable ethylene plastics compounds (Note 0). The requirements specified herein are not necessarily applicable for use as criteria in determining suitability for the end use of a fabricated product.
It is to be noted that this specification describes materials that are available commercially in their uncrosslinked form. Therefore, they are crosslinkable compounds despite the fact that measurement of the parameters used for their classification and specification will usually be carried out after curing has been effected.
1.2 Two types of compounds are covered, namely, mechanical types in which mechanical strength properties are of prime importance in applications, and electrical types in which electrical insulating or conducting properties also are of prime importance in applications.
1.3 The parameters used to classify and specify the mechanical types are ultimate elongation, elongation retention after aging, apparent modulus of rigidity, and brittleness temperature.
1.4 The parameters used to classify and specify the electrical types are ultimate elongation, elongation retention after aging, apparent modulus of rigidity, brittleness temperature, dielectric constant, dissipation factor, and volume resistivity.
1.5 The values stated in SI units are to be regarded as the standard. The values given in brackets are for information only.
The following safety hazards caveat pertains only to the test methods portion, Section , of this specification: This specification does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
There is no similar or equivalent ISO standard.
