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

ASTM G44 Alternate Immersion Corrosion Testing

Information Discussion 0 Files Holdings. Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material being tested.

It is primarily for tests of aluminum alloys Test Method G47 and ferrous alloys, but may be used for other metals. For example, it does not predict the performance of aluminum alloys in highly acidic environments such as heated inhibited red fuming nitric acid IRFNA.

Note 2 — The alternate immersion concept can be useful for exposure of corrosion specimens in other g44 because the procedure and apparatus provide a controlled set of conditions.

Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material being tested. Details of this are beyond the scope of this practice. Note 1 — Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D The general atsm of 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 wstm of the safety concerns, if any, associated with its use.

The values given in parentheses are for information only. The general requirements of 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 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.

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.

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. Work Item s – proposed revisions of this standard. It sets forth the environmental conditions of the test and the means for controlling them. Consequently, information should be established to allow comparisons of performances of the alloy of interest in the alternate immersion test and in natural environments.
