10.0 ACCEPTANCE CRITERIA
The purpose of this procedure is intended to provide the customer and involved authorities with information concerning methods, techniques .equipment and personnel to employed in carrying out magnetic particle inspection ,Wet and Dry Non-fluorescent continuous method by AL-NABAA Inspection services.
Excluded from the scope of this procedure is MPI by the use of prods. Should this method of testing become necessary then this procedure shall be reviewed accordingly.
This procedure establishes minimum requirement for magnetic particle testing (Wet and DRY non-fluorescent continuous )to be perform by AL-NABAA inspection services NDT personnel. The magnetic particle inspection shall be used to detect crack and other discontinuities at or near the surface of the weld , raw material , billet , blooms, castings and forgings like ferromagnetic materials by electromagnetic yokes and permanent magnetic yokes.

MPIshall also mean Magnetic Particle Inspection or Magnetic Particle Testing (MT/MPT),the process of Non-Destructive Testing where by a magnetic field is induced into the test area and with the application of very fine iron particles suspended in a liquid. Detects surface or near-surface discontinuities by means of distortions in the normal magnetic field.

ACWhere used in this procedure indicates an alternating electrical current.Compatible with the specification of the equipment being used.
AL-NABAA personnel employed to conduct MPI shall be qualified to ASNT Level II or equivalent and approved by the client.
All equipment and consumable used in performing MPI shall be of the type specified by the client or agreed equivalent.
The magnetizing force of yokes is calibrated by the determining the lifting power. Pre-inspection calibration checks shall be conducted as specified in subsection 9.3 of this procedure
Inspector or Technicians shall ensure environmental conditions are suitable for use of inspection, measuring and test equipment used in inspection. Actions shall be taken to safeguard the equipment against. Damage or accidental adjustments that would invalidate calibration or prevent operating systems from functioning correctly.
Appropriate personnel protective Equipment for the task being carried out shall be worn. Consideration shall be given to the working environment for example
Construction site activities , Fabrication shop activities, Working in confined spaces, Thoseassociatedwiththematerialsbeingused,notemanufactures instructions, Those associated with the equipment being used and electrical connectionsetc,9.0PROCEDURE
9.1 Surface preparationSurface to be inspected shall be cleaned by the contract and shall be freefrom oil, grease thick paint ,loose rust, scale , which may interfere with satisfactory testing .welds shall be cleaned and dressed prior to testing and shall be free from spatter and stag. The operator /technician shall inform the client if he decides further cleaning is necessary, e.g. by grinding .9.2 INSPECTION MEDIUM9.2.1 The magnet particles used in the examination shall have high permeability,low retentively suitable size and shapes to produce magnetic particle indication.9.2.2 For wet method inspection with colored particles.,(non-fluorescent), the inspection medium used shall be of the black magnetic ink type delivered either by aerosol or by a manually charged system . the concentration of particle shall be as specified or recommended by the manufacturers. Inks shall be of an internationally accepted standard
9.2.3 A removable white medium shall be used to ensure that a good surface contrast is obtained .the contrast medium may be applied by either aerosol or brush. In both cases care shall be taken to ensure an even coating.9.2.4 For dry method of inspection the magnetic particle used shall be an international standard and shall be applied using a rubber bulb applicator.The color shall be selected in order to provide adequate contrast with the surface being examined.9.2.5 The following Magnetic Particle material or equivalent (section 6.0) shall be used.Black magnetic ink:MR 70Or equivalent White Background Lacquer :MR 70 S Or equivalent9.2.6 Where applicable testing shall be made after P.W.H.T. For non P.W.H.T.weld meant, at a minimum of 24 hours after the completion of welding .9.3 Magnetization9.3.1 permanent U shape magnet.AC or DC yokes shall be used .9.3.2 Each alternating current electromagnetic yoke shall have a lifting power of at least10 lb. (4.5Kg) at the maximum poles pacing that will be used .9.3.3 Each direct current electromagnetic yoke or the permanent magnetic yoke shall have a lifting power of at the least 40 lb. (18Kg) at the maximum pole spacing that will be used.
The lifting capacity of the magnet shall be verified at the start of the working shift as per procedure AN-QA-NDT-MT-07-10: Control of Measuring and Monitoring Devices .
9.3.4 portable flux indictors shall be used to assess the intensity and direction of the magnetic field at the surface , e.g Burmuh Castrol flux strips according to ASME code.9.4 Examination9.4.1 the examination procedure to identify any surface or near surface defects shall be in accordance with ASME BPV Code .Section V ,Article 7 and shall be reported in accordance with this procedure.9.4.2 Examination shall be conducted with the surface to be tested under continuous magnetization whilst the inspection medium is being applied.9.4.3 At the least two separate examinations shall be conducted on each test with the lines of magnetic flux perpendicular to each other from one examination to the second .9.4.4 Inspection shall be conducted with sufficient over tap to ensure 100 percent coverage.
9.4.5 Inspection shall not be carried out if the surface temperature exceeds the 40 degrees C for wet continuous magnetization technique.9.5 Examination Area9.5.1 Magnetic particle Testing indications may be inspected in either natural or artificial white light. The intensity of visible light at the surface of the part/work piece undergoing examination should be a minimum of 1000 lux and verified with lux meter where applicable.9.5.2 For some field inspections ,visible light intensities 500 lux may be usedwhen agreed on by the contractor .9.6 Demagnetization
9.6.1 Demagnetization shall be required following final magnetic particle9.6.2 When demagnetizing with yoke use alternating current and energies the yoke. When it is in contact with the test object, with current still applied separate the test object or yoke relative to one another.9.7 Post Cleaning
Remove all traces of magnetic particle and the vehicles from the test object. Cleaning Shall be done with suitable solvent or by other means.
The magnetic particle indication interpretation shall be as per one of the criteria in depending on ASME Code Latest version the applicable code. Where there is specific client requirement not cover in the acceptance criteria in the appendices project specific procedure shall be derived from this procedure.
