3.1?The boiling ferric sulfate-sulfuric acid test may be applied to the following alloys in the wrought condition:
3.2?This
test method may be used to evaluate as-received material and to
evaluate the effects of subsequent heat treatments. In the case of
nickel-rich, chromium-bearing alloys, the test method may be
applied to wrought and weldments of products. The test method is
not applicable to cast products.

1.1?These test methods cover two tests as follows: 1.1.1?Method A, Ferric Sulfate-Sulfuric Acid Test 1.1.2?Method B, Mixed Acid-Oxidizing Salt Test 1.2?The purpose of these two test methods is to detect susceptibility to intergranular corrosion as influenced by variations in processing or composition, or both. Materials shown to be susceptible may or may not be intergranularly corroded in other environments. This must be established independently by specific tests or by service experience. 1.3?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1?ExceptionSome desired corrosion rate units in 8.1.1 are given in inch-pound units. 1.4?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
