This practice also emphasizes the importance of recording all pertinent data and provides a checklist for reporting test data.

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. Link to Active This link will always route to the current Active version of the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These factors include specimen preparation, apparatus, test conditions, methods of cleaning specimens, evaluation of results, and calculation and reporting of corrosion rates.

Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. It should be used as a reference to ensure that the test atsm allow generation of data relevant to the application with the minimum of interferences.

One purpose for this guide is to promote better correlation aetm results in the future and the reduction of conflicting reports through a more detailed recording of meaningful factors and conditions. The values given in parentheses are for information only. In many such cases, corrosion rates are established by mass gain rather than mass loss.

This standard, rather than a standardized procedure, is presented as a guide so that some of the pitfalls of such testing may be avoided. These factors include apparatus, sampling, test gg31, 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.

It is impractical to propose an b31 standard laboratory corrosion testing procedure for general use, except for material qualification tests where standardization is required.

This guide also emphasizes the importance of recording all pertinent data and provides a checklist for reporting test data.

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. Corrosion testing by its very nature precludes complete standardization. Active view current version of standard. The values given in parentheses are for information only.

Warning- In many cases the corrosion product on the reactive metals titanium and zirconium is a hard and g311 bonded oxide that defies removal by chemical or ordinary mechanical means.
