19、e federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that
20、 committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in ac
21、cordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard req
22、uires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

31、s 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 before or during pipe production. NOTE 1 For welded tubes, an alternative ultrasonic testing specification for the detection of lamina
32、r 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 ISO 10893-8. NOTE 2 By agreement between the purchaser and manufacturer, the requirements of this part of ISO 10893 can be applied on
33、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 of circular hollow sections. 2 Normative references The following referenced documents are indispensable for the application of this d
