Anotace textu normy ASTM A363-03(2020)e1 :
This specification covers high strength, extra-high-strength, and utilities grades of concentric lay steel wire strand composed of three wires or seven wires in class A, class B, or class C zinc coatings specifically intended for use as overhead ground wires or static wires for electric transmission lines. The strand shall have a left lay with a uniform pitch of not more than 16 times the nominal diameter of the strand. The strand is preformed when the component wires are set to the helical form which they assume in the product by any means of process other than by merely laying them about the strand core. The approximate weight per unit length of strand and the minimum breaking strength of the finished strand are presented. The elongation shall be measured as the percentage increase in separation between the jaws of the testing machine from the position after application of the initial load, to the position of at initial failure in the test specimen.
