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.

Therefore, strict test conditions are stipulated for maximum assurance that variations in results are attributable to variations in the material being tested. Note 1 — Alternate immersion stress corrosion exposures are sometimes made in substitute ocean water without heavy metals prepared in accordance with Specification D 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.

Note Reapproved Subject category Engineering Abstract 1. 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 aetm Specification D It sets forth the environmental conditions of the test asttm the means for controlling them.

ASTM G44 Alternate Immersion Corrosion Testing

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 conditions. This standard does not purport to address y44 of the safety concerns, if any, associated with its use.
