ASTM G44 Standard Practice for Alternative Immersion Exposure of Metals and Alloys to Sodium Chloride Solution

EUROLAB laboratory provides testing and compliance services within the scope of ASTM G44 standard. This application covers procedures for performing alternative immersion stress corrosion tests in 3,5% sodium chloride (NaCl).

Primarily for testing aluminum alloys (Test Method G47) and ferrous alloys, but can also be used for other metals sensitive to chloride ions. It sets out the environmental conditions of the test and the means of controlling them.

Alternative immersion stress corrosion exposures are sometimes made in substitute ocean water (without heavy metals) prepared to Specification D1141. The general requirements of this current practice also apply to such exposures, except that the reagents used, solution concentration and solution pH are as specified in Specification D1141.

This application can be used for both stress and stress-free corrosion samples. Historically, stress corrosion has been used for cracking testing, but is often used for other types of corrosion such as uniform, pitting, intergranular, and galvanic.

This application is intended for applications where alloy development and alternative dip testing will serve as a control test on the quality of successive batches of the same material. Therefore, strict test conditions are stipulated for maximum assurance that changes in results can be attributed to changes in the material tested.

Values ​​stated in SI units will be accepted as standard. Values ​​in parentheses are for informational purposes only.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
