30、011-07 EN ISO 10893-3:2011 (E) 1 Scope This part of ISO 10893 specifies requirements for automated full peripheral magnetic flux leakage testing of seamless and welded ferromagnetic steel tubes, with the exception of submerged arc-welded (SAW) tubes, for the detection of imperfections. Unless otherw
31、ise specified in the purchase order, this part of ISO 10893 is applicable to the detection of predominantly longitudinal imperfections. This part of ISO 10893 is applicable to the inspection of tubes with an outside diameter equal to or greater than 10 mm. This part of ISO 10893 can also be applicab
32、le to the testing of hollow sections. 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 document (including any amendment
33、s) applies.

36、made by piercing a solid product to obtain a tube hollow, which is further processed, either hot or cold, into its final dimensions 3.6 welded tube tube made by forming a hollow profile from a flat product and welding adjacent edges together, and which after welding can be further processed, either
37、hot or cold, into its final dimensions 3.7 manufacturer organization that manufactures products in accordance with 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 t
38、he manufacturer and purchaser at the time of enquiry and order 4 General requirements 4.1 Unless otherwise specified by product standard or agreed on by the purchaser and manufacturer, this peripheral magnetic flux leakage inspection shall be carried out on tubes after completion of all the primary
39、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 the test. The surfaces shall be sufficiently free of foreign matter which can interfere with the vali
40、dity 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 purchaser an
41、d manufacturer. The operating authorization issued by the employer shall be according to a written procedure. NDT operations 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. IS
42、O 9712 and ISO 11484. 5 Test method 5.1 The tubes shall be tested using the magnetic flux leakage technique for the detection of predominantly longitudinal imperfections (see Figure 1) and/or, by agreement, predominantly transverse imperfections (see Figure 2). No limits on thickness are specified;
43、indications on the limits of the method are reported in Annex A. It is recognized that there can be a short length at both tube ends which cannot be tested. Any untested ends shall be dealt with in accordance with the requirements of the appropriate product standards. 5DIN EN ISO 10893-3:2011-07 EN

The relative speed during testing shall not vary by more than g11410 %. 5.3 The maximum width of each individual transducer, measured para
45、llel to the major axis of defects being detected, shall be 30 mm. 5.4 The equipment shall be capable of classifying tubes as either acceptable or suspect tubes by means of an automated trigger/alarm level combined with a marking and/or sorting system. a) Rotating magnetic transducer technique Linear
