The work of preparing International Standards is normally carried out through I
19、SO 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 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
20、closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards.
21、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 some of the elements of this d
22、ocument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10675-2 was prepared by the European Committee for Standardization (as EN 12517-2:2008) and was adopted, under a special “fast-track procedure”, by Technical Committee IS
23、O/TC 44, Welding and allied processes, Subcommittee SC 5, Testing and inspection of welds, in parallel with its approval by the ISO member bodies. Request for official interpretations of any aspect of this part of ISO 10675 should be directed to the Secretariat of ISO/TC 44/SC 5 via your national st

25、of ISO 10675 specifies acceptance levels for indications from imperfections in aluminium butt welds detected by radiographic testing. If agreed, the acceptance levels may be applied to other types of welds or materials. The acceptance levels may be related to welding standards, application standards
26、, specifications or codes. This part of ISO 10675 assumes that the radiographic testing has been carried out in accordance with ISO 17636. 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
27、dimensions of indications revealed by a radiograph made of the weld. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced do

31、E) 2 ISO 2010 All rights reserved4 General Welded joints should be visually tested in accordance with ISO 17637 and evaluated before radiographic testing. The acceptance levels in this part of ISO 10675 are basically valid for evaluation of imperfections which cannot be detected and evaluated by vis
32、ual testing (Table 2). Surface imperfections (Table 3; such as undercut and excessive penetration, surface damage, weld spatter, etc.) which due to object geometry cannot be evaluated, but where the interpreter suspects the ISO 10042 quality levels are not fulfilled, shall be subject to more specifi
33、c testing. When quantification of undercut and/or excessive penetration by radiographic testing is required, specific procedures using test exposures may be applied in order to establish a basis for approximate quantification in accordance with the requirements of ISO 10042. This shall be specified.
34、 5 Acceptance levels The acceptance levels for indications are shown in Tables 2 and 3. The types of imperfections are selected from ISO 10042 and defined in ISO 6520-1. The symbols used in Tables 2 and 3 are the following: A sum of projected areas of indications related to L wpin %; b width of exce
35、ss penetration of weld, in millimetres; d diameter of pore, in millimetres; dAdiameter of area surrounding a cluster, in millimetres; h width of indication, the width or height of surface or cross surface imperfection, in millimetres; l length of indication, in millimetres; L any 100 mm testing leng
36、th, in millimetres; s nominal butt weld thickness, in millimetres; t material thickness, in millimetres; wpwidth of the weld in millimetres; l summary length of imperfections within L. Any two adjacent imperfections separated by a distance smaller than the major dimension of the smaller imperfection
37、 shall be considered as a single imperfection. Indications shall not be divided into different ranges L.
