New standard: BS EN ISO 6520:2007 for weld imperfections
BS EN ISO 6520-1:2007 Welding and allied processes. Classification of geometric imperfections in metallic materials. Fusion welding is a new international standard that serves as the basis for a precise classification and description of weld imperfections. In order to avoid any confusion, the types of imperfection are defined with explanations and illustrations where necessary. Metallurgical imperfections are not included.
Note, however, that another system for the designation of imperfections is possible, according to ISO/TS 17845. BS EN ISO 6520-1:2007 therefore shows how the existing classification of imperfections according to ISO 6520-1 correspond to the new BS EN ISO 6520-1 classifications, and the designation system according to ISO/TS 17845 is also included.
BS EN ISO 6520-1 gives the terms and definitions used in two of the three official ISO languages (English and French). It also gives the equivalent terms and definitions in the German language.
BS EN ISO 6520:2007 replaces BS EN ISO 6520-1:1998, which has been withdrawn. It is priced at £142 (+ P&P) or £71 for Members of BSI.
