ISO consists of the following parts, under the general title Non-destructive testing of steel tubes: If these details are to be used for any other purpose than implementation then the prior written permission 18093-1 BSI must be obtained. The higher the excitation frequency, the lower the penetration and conversely, the lower the excitation frequency, the higher the penetration.

The work of preparing International Standards is normally carried out through ISO technical committees.

It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux leakage method. After agreement, the non-destructive 1089-31 of EN ISO can be carried out on hollow sections which are used in steel construction. This document supersedes EN Attention is drawn to the possibility enn some of the elements of this document may be the subject of patent rights.

The operating authorization issued by the employer shall be according to a written procedure. Subscription pricing is determined by: The manufacturer shall wn, on request, the effectiveness of the adopted solution.

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.

NOTE 2 In special cases, for example testing hot tubes or using equipment contained within a continuous tube mill, a modified calibration or calibration checking procedure can be used, by agreement. Essais non destructifs des tubes en acier. This first edition cancels and replaces E Radiographic testing of weld seams with X-rays has been established for testing safety-relevant tubes for example, in nuclear technology.

The sides shall be nominally parallel and the bottom shall be nominally square to the sides. You may experience issues viewing this site in Internet Explorer 9, 10 or Ultrasonic testing is the usual test method for all tube thicknesses and tube diameters; it is the preferred test method especially for thick-walled tubes.

We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical com- mittee responsible, the identity of which can be found on the inside front cover. As the voice of the U. The surfaces shall be sufficiently free of foreign matter which can interfere with the validity of the test. It is recognized that longitudinal imperfections are not normally detectable unless they have a significant transverse component oblique.

We have no document history for this standard. This publication does not purport to include all the necessary provisions of a contract.

It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux leakage method. For specified wall thickness exceeding 10 mm, the wall thickness of the reference tubes may be greater than the specified wall thickness of the pipe being inspected, provided the notch depth is calculated on the specified wall thickness of the pipe being inspected.

NOTE The pancake coils in a and b can have different forms, e. In particular, the physical parameters of the tube conductivity, permeability, etc.

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. In addition to the three standardized methods, dye penetration testing see Part 4 and the magnetic particle inspection see Part 5which are used to detect surface imperfections shall be mentioned.

Ej pricing is determined by: Figure 5 — Simplified diagram of magnetic flux leakage technique for the detection of transverse imperfections 6 Reference tube 6. 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.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. During the fIux leakage testing of tubes, the sensitivity of the test is at a maximum at the tube surface adjacent to the magnetic transducer and decreases with increasing tube thickness due to effective diminishing wn diversion from imperfections at the tube bore surface in relation to that at the external surface.
