Abstract

This specification covers the requirements for sacrificial anodes of zinc alloy in the form of slabs, plates, discs, and rods for corrosion protection (cathodic protection) of metals and alloys. These anodes are primarily intended to reduce corrosion of surface ship and submarine hulls, steel and aluminum equipment and structures, sea chests, sonar domes, and the seawater side of condensers and other heat exchangers. The anodes are available either as cast-in cores (Class 1) or plain with no cores (Class 2). Class 1 anodes shall be of the following types: Type ZHShull slabs with steel straps; Type ZHBhull slabs with brass straps; Type ZHChull slabs with core straps; Type ZSSsubmarine slabs with steel straps; Type ZTSteardrop shapes with steel straps; Type ZEPheat exchanger or fair water discs (pipe core or pipe bushing core) that are in the form of square slabs (Style A), circular slabs (Style B), and semicircular slabs (Style C); Type ZBPbars with pipe cores; and Type ZDMsegmented discs with machine formed interlocking cores. Conversely, Class 2 anodes shall be of the following types: Type ZRNextruded, drawn or rolled rods; and Type ZPNrolled plates. Anodes shall conform to material and manufacture, chemical composition, mechanical property, and dimensional requirements specified uniquely for each type.

Scope

1.1 This specification covers the requirements for zinc anodes in the form of slabs, plates, discs, and rods for corrosion protection (cathodic protection) of metals and alloys.

1.2 The anodes are primarily intended to reduce corrosion of surface ship and submarine hulls, steel and aluminum equipment and structures, sea chests, sonar domes, and the seawater side of condensers and other heat exchangers.

1.3 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.

1.4 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
