ASTM D2647-18(2024)

Anotace textu normy ASTM D2647-18(2024) :

This specification covers a general classification system for crosslinkable ethylene plastics compounds. 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. These compounds shall be classified as: Type I; Type II; and Grade A. Tests shall be performed to determine the properties in accordance with the following test methods: conditioning; test conditions; ultimate elongation; elongation retention after aging; apparent modulus of rigidity; brittleness temperature; dielectric constant; dissipation factor; and degree of crosslinking.
