ASTM G78 Crevice Corrosion Testing of Stainless Alloys in Seawater
Add to Alert PDF. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. 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. It allows a fast screening of pores, discontinuities and other faults in organic and anorganic coatings.
Because of the many interrelated metallurgical, environmental, and geometric factors known to affect crevice corrosion, results from any given test may or may not be indicative of actual performance in service applications where the conditions may be different from those of the test.
