19、eservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for wh
20、ich 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 closely with the International Electrotechnical Commission (IEC) on all
21、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. Draft International Standards adopted by the technical committees are ci
22、rculated 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 document may be the subject of patent rights. ISO shall not be held respo
23、nsible for identifying any or all such patent rights. ISO 10893-2 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 19, Technical delivery conditions for steel tubes for pressure purposes. This first edition cancels and replaces ISO 9304:1989, which has been technically revised.
24、ISO 10893 consists of the following parts, under the general title Non-destructive testing of steel tubes: Part 1: Automated electromagnetic testing of seamless and welded (except submerged arc-welded) steel tubes for the verification of hydraulic leaktightness Part 2: Automated eddy current testing
25、 of seamless and welded (except submerged arc-welded) steel tubes for the detection of imperfections Part 3: Automated full peripheral flux leakage testing of seamless and welded (except submerged arc-welded) ferromagnetic steel tubes for the detection of longitudinal and/or transverse imperfections
26、 Part 4: Liquid penetrant inspection of seamless and welded steel tubes for the detection of surface imperfections Part 5: Magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections Part 6: Radiographic testing of the weld seam of welded
27、steel tubes for the detection of imperfections Part 7: Digital radiographic testing of the weld seam of welded steel tubes for the detection of imperfections Part 8: Automated ultrasonic testing of seamless and welded steel tubes for the detection of laminar imperfections Part 9: Automated ultrasoni

32、wn in Tables 1 and 2. It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm. This part of ISO 10893 can also be applicable to the testing of hollow sections. 2 Normative references The following referenced documents are indispensable for the application o

38、the relevant standard(s) and declares the compliance of the delivered products with all applicable provisions of the relevant standard(s) 3.8 agreement contractual arrangement between the manufacturer and purchaser at the time of enquiry and order 4 General requirements 4.1 Unless otherwise specifie
39、d by the product standard or agreed on by the purchaser and manufacturer, this eddy current inspection shall be carried out on tubes after completion of all the production process operations, such as rolling, heat treating, cold forming and hot working, sizing and primary straightening. 4.2 The tube
40、s being tested shall be sufficiently straight to ensure the validity of the test. The surfaces shall be sufficiently free of foreign matter which can interfere with the validity of the test. 4.3 This inspection shall be carried out by trained operators qualified in accordance with ISO 9712, ISO 1148
41、4 or equivalent and supervised by competent personnel nominated by the manufacturer. In the case of third-party inspection, this shall be agreed on between the purchaser and manufacturer. The operating authorization issued by the employer shall be according to a written procedure. NDT operations sha
42、ll be authorized by a level 3 NDT individual approved by the employer. NOTE The definition of levels 1, 2 and 3 can be found in appropriate International Standards, e.g. ISO 9712 and ISO 11484. 5 Test method 5.1 Test techniques 5.1.1 The tubes shall be tested by the eddy current method for the detec
43、tion of imperfections using in “absolute mode” and/or in “differential mode” one of the following alternative automated or semi-automated techniques: a) concentric coil technique full peripheral (see Figure 1); b) fixed or rotating probe/pancake coil technique full peripheral (see Figure 2); c) segm
44、ent coil technique weld seam only (see Figure 3) or full body (see Figure 4). For all techniques, the chosen relative speed of movement during the testing shall not vary by more than 10 %. It is recognized that there may be a short length at both tube ends which cannot be tested. Any untested ends s
45、hall be dealt with in accordance with the requirements of the appropriate product standards. NOTE See Annex A for guidelines on the limitations of the eddy current test method. BS EN ISO 10893-2:2011ISO 10893-2:2011(E) ISO 2011 All rights reserved 35.1.2 When testing tubes using the concentric coil
46、technique, the maximum tube outside diameter that shall be tested shall be restricted to 180 mm (250 mm for E4H). Square and rectangular tubes, used for structural purposes, with a maximum dimension across the diagonal of 180 mm may also be tested using this technique with adequately shaped coils. 5
47、.1.3 When testing tubes using the rotating or fixed probe/pancake coil technique, the tube and the probe/pancake coil shall be moved relative to each other or the movement shall be simulated by electronic commutation through the individual probes composing the pancake, such that the whole of the tub
48、e surface is scanned. There is no restriction on the maximum tube outside diameter using this technique. NOTE It is emphasized that only external surface breaking imperfections can be detected using this technique. 5.1.4 When testing the weld of welded tubes using the segment coil technique, there i
49、s no restriction on the maximum tube outside diameter. The test coil shall be maintained in proper alignment with the weld, such as that the whole of the weld is scanned. 5.1.5 When testing the full body of tubes using the segment coils technique, the maximum tube outside diameter that shall be tested shall be limited to: 219,1 mm for 2 180 coils, 508,0 mm for 4 100 coils. NOTE It is emphasized that the test sensitivity is at a maximum at the tube surface adjacent to the test coil and decreases w
