The higher the excitation frequency, the lower the penetration and conversely, the lower the excitation frequency, the higher the penetration. NOTE 1 It is recognized that there can be, as in the case of hydraulic testing under normal production conditions, a short 1093-1 at both tube ends which cannot be tested.
The main task of technical committees is to prepare International Standards. We have no document history for this standard.
Amendments issued since publication Date Text affected www. Non-destructive testing of steel tubes. 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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. You may delete a document from your Alert Profile at any time.
The most important methods are electromagnetic testing see Parts 1 to 3radiographic testing see Parts 6 and 7and ultrasonic testing see Parts 8 to In this case, the 10839-1 shall demonstrate that the test sensitivity achieved using the reference hole and the equipment settings, for example signal rate filtering, is essentially equivalent to that obtained when using the reference notch.
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. This standard is not included in any packages.
It supersedes BS EN Users of British Stan- dards should make sure that they possess the latest amendments or editions. 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.

This publication does not purport to include all the necessary provisions of a contract. As the voice of the U. The work of preparing International Standards is normally carried out through ISO technical committees. Please first verify your email before subscribing to alerts.
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.
It presents the UK view on standards in Europe and at the international level. Already Subscribed to this document. This first edition cancels and replaces ISO 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.
After checking that the remaining thickness is within tolerance, the tube shall be tested as previously specified. Your basket is empty. NOTE The pancake coils in a and b can have different forms, e. Automated electromagnetic testing of seamless and welded except 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.
NOTE Electromagnetic inspection using magnetic flux leakage method is not applicable to austenitic stainless steel tubes.
