DIN EN ISO 10270:2011-09

This International Standard specifies: a) the determination of mass grain; b) the surface inspection of products of zirconium and its alloys when corrosion tested in water at 360 °C or in steam at or above 400 °C; c) that the tests in steam shall be performed at 10,3 MPa (1 500 psi). This International Standard is applicable to wrought products, castings, powder metallurgy products and weld metals. The method described has already been widely used in the development of new alloys, heat treating practices and for the evaluation of welding techniques, and should be utilized in its entirety to the extent specified for a product acceptance test, rather than merely a means of assessing performance in service. This document (EN ISO 10270:2008) has been prepared by Technical Committee ISO/TC 156 "Corrosion of metals and alloys", the secretariat of which is held by GOST R (Russian Federation) and has been adopted within the framework of the Unique Acceptance Procedure by CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI (Great Britain). The responsible National Committee is NA 062-01-71 AA "Korrosion und Korrosionsschutz" ("Corrosion and corrosion protection") of the Materials Testing Standards Committee (NMP).
