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.
This standard, rather than a standardized procedure, is presented as a guide so that some of the pitfalls of such testing may be avoided. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
It is the responsibility of the user of this standard to establish appropriate g1 and health practices and determine the applicability of regulatory limitations prior to use. This guide also emphasizes the importance of recording all pertinent data and provides a checklist for reporting test data.
These factors include f31, sampling, test specimen, test conditions test solution composition, temperature, gas sparging, fluid motion, solution volume, method of supporting test specimens, duration of testmethods of cleaning test specimens, interpretation of results, and calculation of corrosion rates.

These factors include specimen preparation, apparatus, test conditions, methods of cleaning specimens, evaluation of results, and calculation and reporting of corrosion rates.

It should be used as a reference to ensure that the test will allow generation of data relevant to the application with the minimum of interferences.
