20、pyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-EN IS0 14273:2001 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards
21、bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizat
22、ions, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in th
23、e ISOAEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that s
24、ome of the elements of this International Standard may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 14273 was prepared in collaboration with the International Institute of Welding, which has been approved
25、 by the IS0 Council as an international standardizing body in the field of welding. . 111 Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-EN IS0 14273:2001 Copyright European Com
26、mittee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-EN IS0 14273:2001 Specimen dimensions and procedure for shear testing resistance spot, seam and embossed projection welds 1 Scope This International Sta
27、ndard specifies specimen dimensions and a testing procedure for shear testing of spot, seam and embossed projection welds, in overlapping sheets, in any metallic material of thickness 0,5 mm to 10 mm, where the welds have a maximum diameter of 7dt (where t is the sheet thickness in mm). With welds o
28、f diameter 5dt and G 7dt, the value of shear strength can be underestimated when using the recommended test specimen dimensions. The object of shear testing is to determine the shear force that the test specimen can sustain. 2 Normative reference The following normative document contains provisions
29、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
30、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.
