19、nal 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 which a technical committee has been established has the right to be represented on that committee. Internati
20、onal 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 matters of electrotechnical standardization. International Standards are drafted in accordance with the rul
21、es 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 circulated to the member bodies for voting. Publication as an International Standard requires approval by at
22、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 responsible for identifying any or all such patent rights. ISO 10893-5 was prepared by Technical Committee ISO/T

31、r magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel face at the ends. For the tube body, it specifies requirements for the detection of surface imperfections on all or part of the outside surfac
32、e of tubes. However, by agreement between the purchaser and manufacturer, it can be applicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter. In addition, this part of ISO 10893 can be used, as appropriate, to locate the position of external surfa
33、ce imperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tube surface, and to ensure complete removal of the imperfection after dressing is complete. For the end/bevel face at the ends of plain-end and beveled-end tubes, this part of ISO 10893 sp
34、ecifies requirements for the detection of laminar imperfections which can interfere with subsequent fabrication and inspection operations (e.g. welding and ultrasonic inspection of the welds). This part of ISO 10893 is applicable to the detection of imperfections, other than laminar imperfections, o
35、n the end/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to the orientation of the particular imperfections being detected. It can also be applicable to the testing of hollow sections. 2 Normative references The following referenced documents are indisp

42、quirements 4.1 Unless otherwise specified by the product standard or agreed on by the purchaser and manufacturer, a magnetic particle inspection shall be carried out on tubes after completion of all the primary production process operations (rolling, heat treating, cold and hot working, sizing, prim
43、ary straightening, etc.). 4.2 The surface of the tube and of the end/bevel face at both tube ends being tested shall be sufficiently clean and free of oil, grease, sand or scale or any other foreign matter which can interfere with the correct interpretation of the indications obtained from the magne
44、tic particle inspection. The type of indications, as well as the minimum dimension of the surface imperfections being detected, depends on the specific tube manufacturing process and the surface finish. 4.3 This inspection shall be carried out by trained operators qualified in accordance with ISO 97
45、12, ISO 11484 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 o
46、perations shall 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.

The use of residual magnetism, i.e. application of magnetic particles after initial tube magnetization, is only permitted after prior agreement between the purchaser and manufacturer, but generally not permitted in the case of e
