ASTM-B418 › Standard Specification for Cast and Wrought Galvanic Zinc Anodes
The following bibliographic material is provided to assist you with your purchasing decision:
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.
1.4 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 become familiar with all hazards including those identified in the appropriate Material Data Sheet for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
