![]() ![]() ![]() These include but are not limited to, slag, spatter, oil, scale, rough surface and protective coatings.ĥ.2 Surface preparation by grinding, machining or other methods may be necessary where surface irregularities could mask indications of unacceptable discontinuities.ĥ.3 The temperature of the test surface shall not exceed 135✯ for magnetic inks and 600✯ for dry powders. 5.0 MAGNETIC PARTICLE INSPECTION - SURFACE PREPARATIONĥ.1 Prior to the test the area to be inspected and at least one inch either side shall be free from any features that may inhibit the test or mask unacceptable discontinuities. Burmah Castrol magnetic field indicators Type 1 Brass finish.Ĥ.0 MAGNETIC PARTICLE INSPECTION - PARTS TO BE EXAMINEDĤ.1 Welds in ferritic materials, whether in the as welded or dressed condition and the associated heat affected zones and parent material within at least one inch of the weld on both sides of the weld.Magnaflux 20A Fluorescent Ink concentrate (water based).Magnaflux dry powder (red, yellow or grey colour).The particles gather at areas of magnetic flux leakage and form indications characteristic of the type of discontinuity detected.Ģ.2 Maximum sensitivity is achieved when linear discontinuities are oriented perpendicular to the lines of flux.Ģ.3 The AC electromagnetic yoke technique is restricted to the detection of surface breaking discontinuities.ģ.0 MAGNETIC PARTICLE INSPECTION - EAUIPMENT AND MATERIALSģ.1 This procedure is intended for use with the following equipment and consumables or their equivalent. 2.0 MAGNETIC PARTICLE INSPECTION -DESCRIPTION OF METHODĢ.1 This method involves the magnetisation of an area to be examined and the application of ferromagnetic particles to the surface. 1.0 MAGNETIC PARTICLE INSPECTION - SCOPEġ.1 This procedure give the general requirements for carrying out the examination of welds in ferric materials using the AC electro magnetic yoke technique.ġ.2 This procedure meets the requirements of ASME Section V Article 7 and ASTM E-709-95. This procedure is a draft magnetic particle testing procedure and you need to modify it to meet your project specification. This sample procedure covers AC electromagnetic yoke method. This article provides you with a sample magnetic particle inspection / Testing procedure. ![]()
