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. Details of this are beyond the scope of this practice. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It does not cover tests in which specimens are placed in closed containers into which asgm solution is periodically pumped and asttm specimens not permitted to dry.

Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in b44 material being tested.

It sets forth the environmental conditions of the test and the means for controlling them.
Note 1 — Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D Therefore, strict test conditions are stipulated for maximum assurance that 4g4 in results are attributable to variations in the material being tested.
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.
Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material asstm 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.
Note 1 Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D It sets forth the environmental conditions of the test and the means for controlling them. 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. Note Reapproved Subject category Engineering Abstract 1.
Consequently, information should be established to allow comparisons of performances of the alloy of interest g444 the alternate immersion test and in natural environments. Link to Active Ast link will always route to the current Active version of the 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.

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

For example, it does not predict the performance of aluminum alloys in highly acidic environments such as heated inhibited red fuming nitric acid IRFNA.

Ashm createdlast modified This standard does not purport to address all of the safety concerns, if any, associated with its use. The general requirements of this present practice are also applicable to such exposures except that the reagents used, the solution concentration, and the aztm pH should be as specified in Specification D Note 2 — The alternate immersion concept can be useful for exposure of corrosion specimens in other solutions because the procedure and apparatus provide a controlled set of astj.
