20、al 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 which a technical committee has been e

21、stablished 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 matters of electrotechnical standard

22、ization. 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 circulated to the member bodies for vo

23、ting. 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 responsible for identifying any or all su

32、aulic leaktightness 1 Scope This part of ISO 10893 specifies requirements for automated electromagnetic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for verification of hydraulic leaktightness. It is applicable to the inspection of tubes with an

33、 outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux leakage method. This part of ISO 10893 can also be applicable to the testing of hollow sections. NOTE Electromagnetic inspection using magnetic flux leakage method is not ap

34、plicable to austenitic stainless steel tubes. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、the primary production process operations (rolling, heat treating, cold and hot working, sizing, primary straightening, etc.). 4.2 The tubes being tested shall be sufficiently straight to ensure the validity of test. The surfaces shall be sufficiently free of foreign matter which can interfere with

42、the validity of the test. 4.3 This inspection shall be carried out by trained operators qualified in accordance with ISO 9712, 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 purc
