DIN Standards Committee Welding and allied processes

Overview

This standard specifies a method for performing transverse root, face and side bend tests on the test specimens taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad welds) and cladding without butt welds, in order to assess ductility and/or absence of imperfections on or near the surface of the test specimen. It also gives the dimensions of the test specimen. In addition, this standard specifies a method for performing longitudinal root and face bend tests to be used instead of transverse bend tests for heterogeneous assemblies when base materials and/or filler metal have significant differences in their physical and mechanical properties in relation to bending. It applies to metallic materials in all forms of product with welded joints made by any fusion arc welding process. The International Standard ISO 5173:2009 has been prepared by ISO/TC 44/SC 5 "Testing and inspection of welds" and has been adopted identically as a European Standard. The responsible German standardization committee is Joint Working Committee NA 092-00-05 GA "NAS/NMP: Zerstörende Prüfung von Schweißverbindungen (DVS AG Q 4)" ("NAS/NMP: Destructive tests of welds (DVS AG Q4)") at NAS. With respect to DIN EN 910:1996-05, the following changes have been made: a) title and content adopted from the International Standard; b) revision of clause 2 relating to terms and definitions; c) changes of abbreviations and symbols used; d) Figure 1 has been divided into 8 individual figures; e) material independent dimensions of the specimens.
