Description

ASTM G52-20

Active Standard: Standard Practice for Exposing and Evaluating Metals and Alloys in Surface Seawater

ASTM G52

Scope

1.1 This practice covers conditions for the exposure of metals, alloys, and other materials in natural surface seawater such as those typically found in bays, harbors, channels, and so forth,2 as contrasted with deep ocean testing.3 This practice covers full immersion, tidal zone and related splash, and spray zone exposures.2, 4

1.2 This practice sets forth general procedures that should be followed in conducting seawater exposure tests so that meaningful comparisons may be made from one location to another.

1.3 This practice identifies recommended procedures for evaluating the effects of natural surface seawater on the materials exposed.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
