DANSK DSF/FPREN ISO 20728 PDF

This international Standard specifies a method for the determination of resistance to stress corrosion cracking (SCC) of magnesium alloys. This International Standard covers the method of sampling, the types of specimens, the loading procedure, the type of environment and the Interpretation of results. This International Standard is aimed at the determination of the resistance to SCC as a function of the chemical composition, the method of manufacture and heat treatment of magnesium alloys. This International Standard applies to cast and wrought magnesium alloys in the form of castings, semi-finished products, parts and weldments. Since most natural and many artificial environments contain chlorides, this International Standard can be used to compare the performance of products employed in environments containing chlorides providing that the failure mechanism is not changed. However, the results of this test should not be considered as an absolute criterion for the quality of alloys.
