It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astn of regulatory limitations prior to use. Warning- In many cases the corrosion product on the reactive metals titanium and zirconium is a hard and tightly bonded oxide that defies removal by chemical or ordinary mechanical means.

ASTM G31 – 72() Standard Practice for Laboratory Immersion Corrosion Testing of Metals

In many such cases, corrosion rates are established by mass gain rather than mass loss. It is impractical to propose an inflexible standard laboratory corrosion testing procedure for general use, except for material qualification tests where standardization is required.

One purpose for this guide is to promote better correlation of t31 in the future and the reduction of conflicting reports through a more detailed recording of meaningful factors and conditions.

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

This practice also emphasizes the importance of recording all pertinent data and provides a checklist for reporting test data. Corrosion testing by its very nature precludes complete standardization.
