This document also points out which alloys the tests are intended for, and recommends the most appropriate test when none is specified.

FAQ What is standard Become a member? Corrosion test in nitric acid medium by measurement of loss in mass Huey test.

There are other requirements in these standards over details that are not discussed in this document, and these should be followed, such as conducting bend tests.

Intergranular Corrosion Tests for CRAs

ISO is the most rigorous in terms of defining test methods, and says which alloys should use which test methods as follows:. Certified by ISO Aciers austenitiques et austeno-ferritiques duplex. We use cookies to make our website easier to use and to better understand your needs.
