Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness ISO The operating authorization issued by the employer shall be according to a written procedure. Please first verify your 108931 before subscribing to alerts. Non-destructive tests represent, in addition to destructive mechanical tests, the most important elements of quality assurance for steel tubes. We have no document history for this standard.

These operations shall be repeated for each segment coil. It is recognized that longitudinal imperfections are not normally detectable unless they have a significant transverse component oblique. The dimensions of these standards should not be construed as the minimum size of imperfection detectable by such equipment.

The main task of technical committees is to prepare International Standards. For details of these and other benefits contact Membership Ad- ministration. Add to Alert 108933-1.

By agreement between the purchaser and manufacturer, the suspect area may be retested by other non-destructive techniques and test methods to agreed acceptance levels. The signal response from internal surface imperfections can thus be smaller than that from an external imperfection of the same size.

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. NOTE The magnetic transducers can take different forms, for example absolute and differential, depending on the equipment used and other factors.

Automated electromagnetic testing of seamless and welded 10893–1 submerged arc-welded steel tubes for the verification of hydraulic leaktightness 1 Scope This part of ISO specifies requirements for automated electromagnetic testing of seamless and welded steel tubes, with the exception of submerged arc-welded SAW tubes, for verification of hydraulic leaktightness. Subscription pricing is determined by: In any case, the length of reference notch shall not exceed 50 mm.

In particular, the physical parameters of the tube conductivity, permeability, 100893-1. Please first log in with a verified email before subscribing to alerts.

BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. For specified wall thickness exceeding 10 mm, the wall thickness em the reference tubes may be greater than the specified wall thickness of the pipe being inspected, provided the 108993-1 depth is calculated on the specified wall thickness of the pipe being inspected.


Your Alert Profile lists the documents that will be monitored.

NOTE Electromagnetic inspection using magnetic flux leakage method is not applicable to austenitic stainless steel tubes. After checking that the remaining thickness is within tolerance, the tube shall be tested as previously specified. This document supersedes EN 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 flux diversion from imperfections at the tube bore surface in relation to that at the external surface.

Information on standards BSI provides a wide range of information on national, European and international standards through its Knowledge Centre. The surfaces shall be sufficiently free of foreign matter which can interfere with the validity of the test. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Standards Subsctiption may be the perfect solution. 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. The work of preparing International Standards is normally carried out through ISO technical committees.

For undated references, the latest edition of the referenced document including any amendments applies. It is the constant aim of BSI to improve the quality of our products and serv- ices.
