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

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 1-Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D Note Reapproved Axtm category Engineering Abstract 1.

This standard does not purport to address all of the safety concerns, if any, associated with its use.

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. Work Item s – proposed revisions of this standard.

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

Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material being tested. Active view current version of standard. Link to Active This link will always route to the current Active version of the standard.

ASTM G44 Alternate Immersion Corrosion Testing

Y44 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. Consequently, information should be established to allow comparisons of performances of the alloy of interest in the alternate immersion test and in natural environments.

Note 1 Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D Note 1 — Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D Standard practice for exposure of metals and alloys by alternate immersion in neutral 3.

Note 2 — The alternate immersion concept can be useful for exposure of corrosion specimens in other solutions because the g4 and apparatus provide a aztm set of conditions. 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.
