1. Scope
1.1 This specification covers cast and wrought galvanic zinc anodes for the cathodic protection of more noble metals and alloys in sea water, brackish water, or other saline electrolytes. Type I anodes are most commonly used for such applications. The Type I anode composition in this specification meets the chemical composition requirements of MIL-A-18001J.
1.2 Zinc anodes conforming to this specification may be used in other waters, electrolytes, backfills, and soils where experience has shown that the specified composition is efficient and reliable. Type II anodes are most commonly used for such applications.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
