Part 1 of BS EN ISO 6520 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. Another system for the designation of imperfections is possible, according to DD CEN ISO/TS 17845. The correspondence between the existing classification of imperfections according to EN ISO 6520-1 and the designation system according to CEN 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. Contents of BS EN ISO 6520-1 include: Foreword Introduction Scope Terms and definitions Classification and explanation of imperfections Types of crack Designation Cracking phenomena Correspondence between the existing classification of imperfections and the designation system according to ISO/TS 17845 Bibliography Alphabetical index BS EN ISO 6520:2007 replaces BS EN ISO 6520-1:1998, which has been withdrawn.
