In particular, the physical parameters of the tube conductivity, permeability, etc.
For dated references, only the edition cited applies. Need more than 100893-1 copy? 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. This part of ISO can also be applicable to the testing of hollow sections.
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. 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. Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness ISO 10893-11 The main task of technical committees is to prepare International Standards.
For this reason, the technique detects predominantly transverse imperfections having a minimum length dependant on the circumferential dimension of the transducer. The dimensions of these standards should not be construed as the minimum size of imperfection detectable by such equipment. There is no restriction on the maximum outside diameter using this technique. Search all products by.
These signals shall be used to activate their respective trigger alarm of the equipment.

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 leak-tightness in rn of hydrostatic test.

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. This document supersedes EN NOTE 1 It is recognized that there can 108931, as in the case of hydraulic testing under normal production conditions, a short length at both tube ends which cannot be tested.

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. As the voice of the U.
Please first verify your email before subscribing to alerts. This standard is not included in any packages. The signal response from a subsurface or internal surface imperfection is thus smaller than that from an external surface imperfection of the same size.
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 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 magnetic noises from material itself.
