ASTM B802/B802M-98
(Specification)Standard Specification for Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR)
Standard Specification for Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR)
SCOPE
1.1 This specification covers round, zinc-5% aluminum-mischmetal (Zn-5A1-MM) alloy-coated, steel core wire with three classes of Zn-5A1-MM coating used for mechanical reinforcement in the manufacture of aluminum conductors, steel reinforced (ACSR).
1.2 This specification covers wire of diameter from 0.0500 to 0.1900 in. inclusive.
1.3 The SI values for resistivity are regarded as standard. For all other properties the inch-pound units are regarded as standard and the SI units may be approximate.
1.4 This specification is the companion to SI Specification B802M.
