BS EN ISO 9017:2013 pdf free.Destructive tests on welds in metallic materials一Fracture test
This International standard specifies the sizes of test specimen and the procedures for carrying out fracture tests in order to obtain information about types, sizes and distribution of internal imperfections such as porosities, cracks,lack of fusion, lack of penetration and solid inclusions on the fracture surface.
This International Standard applies to metallic materials in all forms of product with joints made by any fusion welding process with a thickness greater or equal to 2 mm.
The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.
ISO 5817:-1), Welding 一Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded)一Quality levels for imperfections.
ISO 10042, Arc-welded joints in aluminium and its weldable alloys一Guidance on quality levels for imperfections.
EN 970, Non-destructive examination of fusion welds一Visual examination.
Fracture the joint through the weld metal in order to examine the fracture surface. The fracture can be induced by bending or tension, static or dynamic loading. Furthermore, notch dimensions and temperature can be varied to induce the fracture.
For welded joints in pipe, unless otherwise specified in the application standard or by agreement between the contracting parties, the test piece shall provide at least two test specimens.
When carrying outbend tests, equal numbers of specimens shall be tested with the root in tension and the face in tension. If the pipe diameter is too small for removing the required number of test specimens, additional test pieces shall be welded.BS EN ISO 9017 pdf download.
