This document specifies acceptance levels for indications from imperfections in butt welds of steel, nickel, titanium and their alloys detected by radiographic testing. If agreed, the acceptance levels can be applied to other types of welds (such as fillet welds etc.) or materials.

The acceptance levels can be related to welding standards, application standards, specifications or codes. This document assumes that the radiographic testing has been carried out in accordance with ISO 17636-1 for RT-F (F = film) or ISO 17636-2 for RT-S (S = radioscopy) and RT-D (D = digital detectors).

When assessing whether a weld meets the requirements specified for a weld quality level, the sizes of imperfections permitted by standards are compared with the dimensions of indications revealed by a radiograph made of the weld.

This series of documents applies to welding of metallic materials in the manufacture and maintenance of railway vehicles and their components.
This document specifies design and classification rules applicable to the manufacture and maintenance of railway vehicles and their parts. Upon agreement with the customer, drawings issued prior to this document may be subject to the provisions of this European Standard.
This document does not define parameters for the dimensioning (refer to other standards e.g. on fatigue testing).

This document contains terms and definitions applicable to health and safety in welding and allied processes. It is intended to be referenced in other documents dealing with this subject. In cases where such documents provide terms and definitions differing from those contained herein, the terms and definitions given in those documents apply. In the main body of this document, terms are arranged in a systematic order. Annex A to C provide indexes in which all terms are listed alphabetically in English, French and German, with reference to the appropriate subclauses and translations of the terms in each and other languages.

 

NOTE Only the terms given in the

official languages (English, French and

Russian) are to be considered as ISO

terms and definitions. German terms

are published under the responsibility

This document specifies a method for making transverse root, face and side bend tests on 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 document specifies methods to be used instead of transverse bend tests with a former for heterogeneous joints when base materials, heat affected zones and/or weld metal have a significant difference in their physical and mechanical properties in relation to bending. Guided transverse bend tests with a roller and longitudinal bend tests are alternative methods of testing for heterogeneous assemblies.

This document applies to metallic materials in all forms of product with welded joints made by any welding process.
