EN ISO 10893-8:2011 (E) DIN EN ISO 10893-8:2011-07 4 1 Scope This part of ISO 10893 specifies requirements for automated ultrasonic testing for the detection of laminar imperfections a) in the pipe body (full peripheral testing) of seamless and welded, except submerged arc-welded (SAW), steel
31、tubes, or b) in the area adjacent to the weld seam of welded steel tubes, and optionally c) at the ends (full peripheral testing) of seamless and welded tubes. This part of ISO 10893 can also be applicable to the testing of circular hollow sections. NOTE For welded tubes, see ISO 10893-9 for an alte

36、destructive testing equipment (e.g. drill holes, notches, recesses) 3.2 reference tube tube or length of tube containing the reference standard(s) 3.3 reference sample sample (e.g. segment of tube, plate or strip) containing the reference standard(s) NOTE Only the term “reference tube” is used in th
37、is part of ISO 10893, also covering the term “reference sample”. 3.4 laminar imperfection imperfection located in the wall thickness and generally parallel to the pipe surfaces NOTE Its extension can be calculated by measuring its outlined area on the external surface. 3.5 tube hollow long product o
38、pen at both ends, of any cross-sectional shape 3.6 seamless tube tube made by piercing a solid product to obtain a tube hollow, which is further processed, either hot or cold, into its final dimensions 3.7 welded tube tube made by forming a hollow profile from a flat product and welding adjacent edg
39、es together, and which after welding can be further processed, either hot or cold, into its final dimensions 3.8 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 th
40、e relevant standard(s) 3.9 agreement contractual arrangement between the manufacturer and purchaser at the time of enquiry and order 4 General requirements 4.1 Unless otherwise specified by the product standard or agreed on by the purchaser and manufacturer, an ultrasonic testing shall be carried ou
41、t on tubes after completion of all the primary production process operations (rolling, heat treating, cold and hot working, sizing and primary straightening, etc.). 4.2 The tubes under test shall be sufficiently straight to ensure the validity of the test. The surfaces shall be sufficiently free of
42、foreign matter which can interfere with the validity of the test. EN ISO 10893-8:2011 (E) DIN EN ISO 10893-8:2011-07 6 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 th
43、e manufacturer. 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 app
44、roved 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 General 5.1.1 As specified in the product standard, the test shall be executed using an ultrasonic pulse echo technique for the detectio
45、n of laminar imperfections in accordance with 5.2 or 5.3 and/or 5.4. The ultrasound shall be transmitted in the direction normal to the tube surface. 5.1.2 For testing in accordance with 5.2 or 5.3, the relative speed of movement during testing shall not vary by more than 10 %. For determining the e
46、xtent of the laminated suspect area, adjacent suspect areas separated by less than the smaller of the two minor axes of the laminations shall be considered as one lamination. There may be a short length at both tube ends which cannot be tested in the case of testing in accordance with 5.2 or 5.3. An
47、y untested ends shall be dealt with in accordance with the requirements of the appropriate product standards (see also 5.4). 5.1.3 The ultrasonic test frequency that shall be applied shall be in the range of 2 MHz to 10 MHz. 5.1.4 The suggested maximum width of each transducer, or each active apertu
48、re when using phased array transducers, should be 25 mm measured in any direction. However, manufacturers may use larger transducers providing their capability for detecting the adopted reference standard; on request, this capability shall be demonstrated. 5.1.5 The equipment shall be capable of cla
49、ssifying tubes as either acceptable or suspect by means of an automated trigger/alarm level combined with a marking and/or sorting system. 5.1.6 Where manual ultrasonic testing is required, this shall be carried out in accordance with Annex A. NOTE For wall thicknesses less than 5 mm, where difficulties can occur in detecting and sizing laminar imperfections using this method of test, an alternative method of test can be agreed on by the manufacturer and purchaser. 5.2 Full peripheral testing of seamless and welded (ex
