1008-2 The faster, easier way to work with standards. In such a case, an ultrasonic test conducted in either the plate mill or the pipe mill and in the latter case, at the discretion of the manufacturer, in either the flat form or the pipe form, in accordance with EN to acceptance level U2 shall be used. Diameter of the mandrel for bend test e see 9. Where internal machining or grinding is carried out, the angle of the internal taper, measured from the longitu- dinal axis, shall be not greater than: The weld repair work shall be performed using an approved and qualified procedure which, in the case of normalized or quenched and tempered steels, may be based on the recommendations given in EN and EN Fn frequency of ej is to be agreed.

Random testing, details to be determined by the person performing the test. The examination shall be carried out under sufficient lighting conditions by trained personnel with satisfac- tory visual acuity to verify the conformity of the pipes with the requirements of 8. Alloy fine grain steel tubes. Test method EN When this examination fails to disclose mechanical damage as the cause of the irregular surface, ej indicates that the irregular surface may be attributed to a hard spot, the dimensions of the area and, if necessary see 8.
For example, rich gas or two-phase fluids may require additional testing to be carried out. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member.
