BS EN ISO 20728:2018 PDF

Scope: What is ISO 20728 - Corrosion of metals and alloys about? ISO 20728 is a safety standard on corrosion of metals and alloys. An alloy is a  mixture  of  chemical elements  of which at least one is a  metal. ISO 20728 specifies a method for the determination of resistance to stress corrosion cracking (SCC) of magnesium alloys intended for use in structural applications (such as magnesium front end, gearbox and clutch housing units, steering column parts, shift actuators, valve covers, and housings, brackets, and intake manifold blades, electronic devices, power tools, and medical equipment). The method allows the determination of the resistance to SCC as a function of the chemical composition, the method of manufacture, and heat treatment of magnesium alloys. ISO 20728 is applicable to cast and wrought magnesium alloys in the form of castings, semi-finished products, parts, and weldments and covers the method of sampling, the types of specimens, the loading procedure, the type of environment, and the interpretation of results. ISO 20728 allows assessment of the relative performance of ...
