NOTE The pancake coils in a and b can have different forms, e. Already Subscribed to this document. Theconsensus reached at an international level on carrying out non-destructive testing on steel tubes is another step towards worldwide harmonization on the international pipe market. These operations shall be repeated for each segment coil. Automated full peripheral ultrasonic thickness testing of seamless and welded except submerged arc-welded steel tubes www.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. NOTE The magnetic transducers can take different forms, for example absolute and differential, depending on the equipment used and other factors. When using a single reference hole in the sample test pipe, the sample test pipe shall be passed through the inspection equipment with the reference hole, on successive runs positioned as requested in 6.

ISONon-destructive testing — Qualification and certification of personnel ISOSteel products — Employer’s qualification system for non-destructive testing NDT personnel 3 Terms and definitions For the purposes of this document, the 108931- and definitions given in ISO em the following apply. Ultrasonic testing is the usual test method for all tube 108893-1 and tube diameters; it is the preferred test method especially for thick-walled tubes.
For this reason, this technique detects longitudinal imperfections with a minimum length dependent on the width of the test coil and the inspection helical pitch. Amendments issued since publication Date Text affected www. There is no restriction on the maximum outside diameter using this technique. Each segment coil shall be checked with the reference tube, and the three holes shall be displaced as follows: Essais non destructifs des tubes en acier.
NOTE 1 It is recognized that there can be, as in the case of hydraulic testing under normal production conditions, a short length at both tube ends which cannot be tested. The main task of technical committees is to prepare International Standards.
BS EN ISO 10893-1:2011
The means of introducing magnetic flux in a direction parallel to the major axis of the tube can be achieved by methods other than that shown in this figure. Information on standards BSI provides a wide range of information on national, European and international standards through its Knowledge Centre.
It is recognized that transverse imperfections are not normally detectable. They are widely used, often during production, for quality assurance. The work of preparing International Standards is normally carried out through ISO technical committees. Click to learn more. Proceed to Checkout Continue Shopping. The same equipment settings, for example frequency, sensitivity, phase discrimination, filtering and magnetic saturation, shall be employed.

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. After agreement, the non-destructive tests of EN ISO can be carried out on hollow sections which are used in steel construction.
NOTE The bottom or the bottom corners of the notch can be rounded. A list of organizations represented on this committee can be obtained on request to its secretary. For this reason, these techniques detect longitudinal imperfections with a minimum length dependant on the width of the transducer and the inspection helical pitch.
Sn is drawn to the possibility that some of the elements of this document may be the subject of patent rights. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
We would be grateful if anyone finding an inaccuracy or ambiguity while using 108931- British Standard would inform the Secretary of the technical com- mittee responsible, the identity of which can be found on the inside front cover.
