Note 1 — Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D Ast example, it does not predict the performance of aluminum alloys in highly acidic environments such as heated inhibited red fuming nitric acid IRFNA. Work Item s asm proposed revisions of this standard. It does not cover tests in which specimens are placed in closed containers into which the solution is periodically pumped and the specimens not permitted to dry.

It sets forth the environmental conditions of the test and the means for controlling them.

Historically, it has been used for stress-corrosion cracking testing, but is often used for other forms of corrosion, such as uniform, pitting, intergranular, and galvanic. Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material being tested.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It is primarily for tests of aluminum alloys Test Method G 47 and ferrous alloys, but may be used for other metals exhibiting susceptibility to chloride ions.

Details of this are beyond the scope of this practice.

The general requirements g44 this present practice are also applicable to such exposures except that the reagents used, the solution concentration, and the solution pH should be as specified in Specification D This standard does not purport to address all of the safety concerns, if any, associated with its use. Therefore, strict test conditions are ashm for maximum assurance that variations in results are attributable to variations in the material being tested.

ASTM G44 Alternate Immersion Corrosion Testing

Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material being tested. Note Reapproved Subject category Engineering Abstract 1. Consequently, information should be established to allow comparisons of performances of the alloy of interest in the alternate immersion test and in natural environments.

For such cases, the results of the alternate immersion test are of doubtful significance until a relationship has been established between it and anticipated service environments.
