Summary

< div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.1< / span> & #x00a0 This specification covers a general classification system for crosslinkable ethylene plastics compounds (< span class=" Body-link1 cdone" > Note 1< / span> ). The requirements specified herein are not necessarily applicable for use as criteria in determining suitability for the end use of a fabricated product.

< div style=" text-align:left " class=" NoteLevel1" >

< span class=" note cdone" style=" text-transform: uppercase " > Note 1:< / span> & #x00a0 < span class=" note cdone" > 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.< / span>

< / div> < / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.2< / span> & #x00a0 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.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.3< / span> & #x00a0 The parameters used to classify and specify the mechanical types are ultimate elongation, elongation retention after aging, apparent modulus of rigidity, and brittleness temperature.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.4< / span> & #x00a0 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.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.5< / span> & #x00a0 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

< / div> < div class=" SectionLevel2" > < p class=" caveat cdone2" > < span class=" Head3 cdone" > 1.6< / span> & #x00a0 < span style=" font-style:normal font-weight:normal " class=" overriddenformat" > The following safety hazards caveat pertains only to the test methods portion, Section < span class=" Body-link1 cdone" > 7< / span> , of this specification: < / span> This standard 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 standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

< span class=" note cdone" style=" text-transform: uppercase " > Note 2:< / span> & #x00a0 < span class=" note cdone" > There is no known ISO equivalent to this standard.< / span>

< / div> < div class=" SectionLevel2" > < p class=" WTOcaveat cdone2" > < span class=" Head3 cdone" > 1.7< / span> & #x00a0 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
