This sample procedure covers AC electromagnetic yoke method. This procedure is a draft magnetic particle testing procedure and you need to modify it to meet your project specification. The particles gather at areas of magnetic flux leakage and form indications characteristic of the type of discontinuity detected. These include but are not limited to, slag, spatter, oil, scale, rough surface and protective coatings.

For dry powders, test surface be clean and dry. Care shall be taken to avoid possible contamination. Settlement time shall be 30 minutes and settlement volume for the solids shall be as below. Any increase in this value to suit clients specific requirements shall be detailed on the technique sheet.

The bulb shall be allowed to warm up for at least 5 minutes before use. Any increase in these values shall be specified in the technique sheet. This will give its strongest indications when placed across the flux direction. Excess power may be GENTLY blown across the surface to aid interpretation and increase exposure of magnetic particles to any flux leakage present.

All indications need not be relevant. Relevant indications are those caused by leakage flux. Relevant indications due to unacceptable mechanical discontinuities are to be noted, located and sized.

A rounded indication is shape with a length equal to or less than three times its width. The acceptance criteria given hereunder for relevant indications for various codes shall be used in general. All indications are not necessarily defects since certain metallurgical discontinuities and magnetic permeability variations may also produce similar indications which are not relevant to the detection of unacceptable discontinuities. Surface conditioning may precede the re-examination.

Non relevant indications which would mask indications of defects are unacceptable. Linear indications are those indications in which the length is more than three times the width. Rounded indications are indications which are circular or elliptical with the length less than three times the width.

The following relevant indications are unacceptable:. VIII Div. Indications will be revealed by retention of magnetic particles. All such indications are not necessarily imperfections, however, since excessive surface roughness, magnetic permeability variations such as at the edge of Heat Affected Zonesetc. An indication is the evidence of a mechanical imperfection. All surfaces to be examined shall be free of:.

When this Article is specified by a referencing Code Section, the magnetic particle method described in this Article shall be used together with Article 1, General Requirements. The magnetic particle examination method may be applied to detect cracks and other discontinuities on or near the surfaces of ferromagnetic materials. The sensitivity is greatest for surface discontinuities and diminishes rapidly with increasing depth of subsurface discontinuities below the surface.

Typical types of discontinuities that can be detected by this method are cracks, laps, seams, cold shuts, and laminations. The particles will form patterns on the surface where cracks and other discontinuities cause distortions in the normal magnetic field.

These patterns are usually characteristic of the type of discontinuity that is detected. Whichever technique is used to produce the magnetic flux in the part, maximum sensitivity will be to linear discontinuities oriented perpendicular to the lines of flux. For optimum effectiveness in detecting all types of discontinuities, each area is to be examined at least twice, with the lines of flux during one examination approximately perpendicular to the lines of flux during the other.

Written Procedure Requirements Requirements. Magnetic particle examination shall be performed in accordance with a written procedure, which shall, as a minimum, contain the requirements listed in Table T The written procedure shall establish a single value, or range of values, for each requirement.

Procedure Qualification. When procedure qualification is specified, a change of a requirement in Table T identified as an essential variable from the specified value, or range of values, shall require requalification of the written procedure. A change of a requirement identified as a nonessential variable from the specified value, or range of values, does not require requalification of the written procedure.

All changes of essential or nonessential variables from the value, or range of values, specified by the written procedure shall require revision of, or an addendum to, the written procedure.

They answered quickly whenever I had a question, and were very gentle and generous with answering what I am sure were obnoxious questions.

I would use them to book trips again in a heartbeat. The accommodations were incredible, even had the coveted room 202 at the Vik Icelandair Hotel!. My car and GPS were brand new, I was the 2nd person to use the car. It was an amazing trip, and when I come back I will use NV again. Excellent service from the word 'Go'. At one point on the holiday there was a discrepancy between what was on our voucher and what the hotel thought were the arrangements for the evening meal, but after a quick e-mail from me she sorted it out there and then.

Overall a great holiday experience, we were very pleased that after e-mail discussion with our consultant we changed our preferred vehicle to larger AWD type, in particular when travelling through the ice and snow.

We appreciated very much the map with hand written suggestions and all accommodation marked. The written itinerary was an excellent guide. Combined with the GPS supplied meant we did not get lost. We thought the tour was very professionally organised and we had no problems whatsoever and would certainly recommend Nordic Visitor.

However personally we like to travel a little slower and would have liked at least one more 2 night stay in a hotel, as we felt some days seemed too long by the time we got to our accommodation.

We didn't enjoy the Western Fjords as much as the rest of the country and if would recommend others to spend a similar number of days in Iceland but without visiting the Fjords.

The last day we felt was a bit of a rush to get the car back in time as we had an early flight the next day. Thank you for a wonderful holiday. We were very impressed with the efficiency of everything which Nordic Visitor organised. The accommodation was varied and very friendly. The hand- annotated road map was especially useful. We saw things which we would not have found ourselves because they had been highlighted on the map or in the itinerary.

An especial highlight was the haycart puffin tour at Ingolshofthi. Car hire was also an efficient and quick affair, much better than our last car-hire experience in France. We had not realised just how large Iceland is and we would love to return to see the rest of the country. The overall organization was very well executed. We had our reservations made everywhere we went, with pre-booked departures on the tours we wanted to take.

This eliminated the deception of showing up at the counter and being told that the tour is full and not able to register. It allowed us to benefit from every hour we were in Iceland.

The small car was in good condition (Ford Focus). Great service, great suggestions. The map outlined and prepared for us was great, along with ideas and suggestions for each day. It was just enough.

Thank you VERY MUCH.

Guides on our tours were informative, interesting, and very easy to talk to with good senses of humor. Pick up times were prompt. The hotel was great and accomidating. The trip and services were outstanding. We loved Iceland and found the Icelanders to be extremely friendly people.
