EN ISO 10893-9:2011 (E) DIN EN ISO 10893-9:2011-07 4 1 Scope This part of ISO 10893 specifies requirements for the automated ultrasonic testing of strip/plate used in the manufacture of welded tubes for the detection of laminar imperfections carried out in the pipe mill b
29、efore or during pipe production. NOTE 1 For welded tubes, an alternative ultrasonic testing specification for the detection of laminar imperfections is available, which can be applied, at the discretion of the manufacturer, by ultrasonic testing of the tubes subsequent to seam welding according to I
30、SO 10893-8. NOTE 2 By agreement between the purchaser and manufacturer, the requirements of this part of ISO 10893 can be applied on strips/plates of SAW tubes in the pipe form after seam welding. This part of ISO 10893 can also be applicable to the testing of strips/plates used in the manufacture o

38、t shall be sufficiently free of surface irregularities and foreign matter as to ensure the validity of the test. 4.3 This test shall be carried out by suitable trained operators qualified in accordance with ISO 9712, ISO 11484, or equivalent and supervised by competent personnel nominated by the man
39、ufacturer. In the case of third-party inspection, this shall be agreed on by the purchaser and manufacturer. The operating authorization issued by the employer shall be according to a written procedure. Non-destructive testing (NDT) operations shall be authorized by a level 3 NDT individual approved
40、 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 The strip/plate shall be tested using an ultrasonic pulse echo technique for the detection of laminar imperfections, with ultrasound transmit
41、ted in the direction normal to the strip/plate surface or using the ultrasonic through-transmission technique at the discretion of the manufacturer. 5.2 During testing, the strip/plate and the probe assembly shall be moved relative to each other such that the strip/plate surface is scanned along equ
42、idistant scan lines parallel or transverse to the principal rolling direction of the strip/plate, with a minimum coverage and a maximum allowable gap between adjacent scanning tracks, as given in Table 1. For the oscillating technique, the minimum coverage shall be half of the values given in Table
43、1. The relative speed of movement during testing shall not vary by more than 10 %.
