The work of preparing International Standards is normally carried out through ISO technical committees.
This part of ISO specifies requirements for automated electromagnetic 10893-11 of seamless and welded steel tubes, with the exception of submerged arc-welded SAW tubes, for verification of hydraulic leak-tightness in substitution of hydrostatic test.
Please first verify your email before subscribing to alerts. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
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.
Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness ISO Also by agreement, internal longitudinal or transverse notches can be additionally used during flux leakage inspection of pipes having wall thickness lower than 12,7 mm.
NOTE Electromagnetic inspection using magnetic flux leakage method is not applicable to austenitic stainless steel tubes.
Your basket is empty. The capacity of the test equipment to detect subsurface or internal surface imperfections is determined by various factors, but predominantly by the thickness of the tube under test and the eddy current excitation frequency. The intention of this saturation is to normalize and reduce the magnetic permeability of the material in order to increase the penetration capability of eddy current and reduce possible 10893-11 noises from material itself.
These signals shall be used to activate their respective trigger alarm of the equipment. This standard is not included in any packages. Proceed to Checkout Continue Shopping. The faster, easier way to work with standards. They are widely used, often during production, for quality assurance.

You may e issues viewing this site in Internet Explorer 9, 10 or For this reason, these techniques detect longitudinal imperfections with a minimum length dependant on the width of the transducer and the inspection helical pitch. If the document is revised or amended, you will be notified by email. Subscription pricing is determined by: In addition to the three standardized methods, dye penetration testing see Part 4 and the magnetic particle 108931 see Part 5which are used to detect surface imperfections shall be mentioned.
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.
This document supersedes EN NOTE The bottom or the bottom corners of the notch can be rounded. As the voice of the U.
ISONon-destructive testing — Qualification and certification of personnel ISOSteel products — Employer’s qualification system for non-destructive testing NDT personnel 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO and the following apply. Amendments issued 110893-1 publication Date Text affected www.
For undated references, the latest edition of the referenced document including any amendments applies. 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.
For dated references, only the edition cited applies. After agreement, the non-destructive tests of EN ISO can be carried out on hollow sections which are used in steel construction. Take the smart route to manage medical device compliance.

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. Non-destructive testing of steel tubes. We have no amendments or corrections for this standard.
The same equipment settings, for example frequency, sensitivity, phase discrimination, filtering and magnetic saturation, shall be employed. This European Standard 108931 be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Octoberand conflicting national standards shall be withdrawn at the latest by October The dimensions of these standards should not be construed as the minimum ne of imperfection detectable by such equipment.
