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.

Already Subscribed to this document. Non-destructive tests are primarily used on pressure-retaining pipes for chemical, petrochemical and power station industries.
These signals shall be used to activate their respective trigger alarm of the equipment. NOTE The bottom or the bottom corners of the notch can be rounded. Your basket is empty. 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.
You may delete a document from your Alert Profile at any time. For this reason, these techniques detect longitudinal imperfections with a minimum length dependant on the width of the transducer and the inspection helical pitch. 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.
This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Take the smart route to manage medical device compliance.
In this case, the manufacturer 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. Radiographic testing of weld seams with X-rays has been established for testing safety-relevant tubes for example, in nuclear technology.
The minimum length of the longitudinal imperfection which is detectable is principally determined by the search coil arrangement and by the rate of change of section along the length of the imperfection.

The same equipment settings, for example frequency, sensitivity, phase discrimination, filtering and magnetic saturation, shall be employed. The sides shall be nominally parallel and the bottom shall be nominally square to the sides. This part of ISO specifies requirements for automated electromagnetic testing of seamless and welded steel tubes, with the exception of sn arc-welded SAW tubes, for verification of hydraulic leak-tightness in substitution of hydrostatic test.

They are widely used, often during production, for quality assurance. This does not preclude the free use, in the course of implementing the standard of necessary details such as symbols, and size, type or grade designations.

The higher the excitation frequency, the lower the penetration and conversely, the lower the excitation frequency, the higher the penetration.

In the case of third-party inspection, this shall be agreed on between the purchaser and manufacturer. Automated 10893-11 testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness Status: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
This standard is 1089-31 included in any packages. For this reason, the technique detects predominantly transverse imperfections having a minimum length dependant on the circumferential dimension of the transducer.
This standard is also available to be included in Standards Subscriptions. It is the constant aim of BSI to improve the quality of our products and serv- ices. 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 rn front cover.
Square or rectangular tubes with a maximum dimension across the diagonal of mm may also be tested using this technique with adequately shaped coils.
