This specification covers cast and wrought galvanic zin anodes used for the cathodic protection of more noble metals and alloys in sea water, brackish water, other saline electrolytes, or other corrosive environments. The anodes shall undergo chemical analysis and spectrochemical analysis and shall conform to the required chemical compositions of aluminum, cadmium, iron, lead, copper, and zinc.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers cast and wrought galvanic zinc anodes used for the cathodic protection of more noble metals and alloys in sea water, brackish water, other saline electrolytes, or other corrosive environments.

1.2 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-18001K.

1.3 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.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 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 Safety Data Sheet (MSDS) 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.
