Determination of resistance to intergranular corrosion of stainless steels. Part 1: Austenitic and ferritic-austenitic (duplex) stainless steels. Corrosion test in nitric acid medium by measurement of loss in mass (Huey test)

This European standard specifies a method for the determination of the resistance to intergranular corrosion of austenitic stainless steels in a nitric acid medium by measurement of the loss of mass (Huey test). The method is applicable only to austenitic stainless steels supplied in the form of rolled or forged products and tubes and intended to be used in an oxydizing medium (for example concentrated nitric acid).
