BS EN ISO 6520-1:2007 Welding and allied processes. Classification of geometric imperfections in metallic materials. Fusion welding

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BS EN ISO 6520:2007 replaces BS EN ISO 6520-1:1998, which has been withdrawn.

BS EN ISO 6520-2:2002 Welding and allied processes. Classification of geometric imperfections in metallic materials. Welding with pressure

BS EN ISO 6520-2:2002 collects and classifies the possible imperfections in welds made with pressure. A uniform designation is specified. Only the type, shape and dimensions of the different imperfections caused by welding with pressure are included.

Metallurgical deviations are not taken into account. Imperfections produced other than by the welding operation, for example additional stresses, loads or environmental factors are not covered by this standard. Information concerning the consequences of the mentioned imperfections and the use of particular structures is not given because this depends on the specific requirements of the joint.
