The prods are then moved in 994-1 prescribed pattern to cover the required total area. Learn more about the cookies we use and how to change your settings. Current passes through the component. Rounded indications are indications that are circular or 99334-1 and where the length is less or equal to three times the width.
An example of an approximate formula for the current required to achieve a specified tangential field strength in the test zone is given in Annex A In the absence of actual production parts with known discontinuities. Flexible coil The Annex A gives approximate formulae for the current required to achieve a specified tangential field strength.
The current is assumed to be distributed evenly over the surface and shall be derived from the peripheral dimensions. Please download Chrome or Firefox or view our browser tips.

Usually the detection media is a suspension of coloured including black or fluorescent magnetic particles in a carrier fluid. I is the current [A]. NOTE Demagnetization using an alternating field can be achieved by reducing the field strength from an initial value equal to.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Magnetic particle testing Equipment. This document specifies general principles for the magnetic particle testing of ferromagnetic materials. Highest sensitivity is achieved for discontinuities elongated perpendicular to the coil axis. This publication does not purport to include all the necessary provisions of a contract. Waveforms with a crest factor i. The faster, easier way to work with standards. In the case of simple-shaped objects.
T is the wall thickness of the component.
After applying a suspension. Inspection of welded joints. There shall be good contrast between the detection media and the test surface. Magnetic particle testing- Isp 1: Magnetic particle testing is primarily applicable to the detection of surface-breakingdiscontinuities, particularly cracks. We work to protect the security of your information during transmission by using Secure Sockets Layer SSL software, which encrypts information you input. Sufficient time shall be allowed for indications to develop before moving or examining the component or structure under test.
