38、e production process operations, such as rolling, heat treating, cold forming and hot working, sizing and primary straightening. 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
39、 with 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
40、 purchaser and 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 Stand

42、tric coil technique full peripheral (see Figure 1); b) fixed or rotating probe/pancake coil technique full peripheral (see Figure 2); c) segment 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 shal
43、l not vary by more than g11410 %. It is recognized that there may 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. NOTE See Annex A for guidelines on the limitations of the eddy
44、 current test method. 5DIN EN ISO 10893-2:2011-07 EN ISO 10893-2:2011 (E) 5.1.2 When testing tubes using the concentric coil 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, w
45、ith a maximum dimension across the diagonal of 180 mm may also be tested using this technique with adequately shaped coils. 5.1.3 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 sha
46、ll be simulated by electronic commutation through the individual probes composing the pancake, such that the whole of the tube 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 imperfection
47、s can be detected using this technique. 5.1.4 When testing the weld of welded tubes using the segment coil technique, there is 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.
