1) Documentation- written procedures, processes specifications and/or methods used by the vendor in performance and controls of NDT activities.
2) Organization- relationship of NDT organization to management.
3) Environment- the general physical condition of the facility, e.g.,housekeeping, storage, safety, consumable management, equipment.
4) Calibration- process by which an item is checked to a standard.
5) Training- methods used and records maintained to train and retrain NDT personnel
1) Level I- An NDT Level I individual should be qualified to properly perform specific calibrations, specific NDT, and specific evaluations for acceptance or rejection determinations according to written instructions and to record results.The NDT Level I should receive the necessary instruction or supervision from a certified Level II or III individual.
2) Level II- An NDT Level II individual should be qualified to set up and calibrate equipment and to interpret and evaluate results with respect to applicable codes, standards and specifications.The Level II should be thoroughly familiar with the scope and limitations for methods for which qualified and should exercise assigned responsibilities for OJT training and guidance of trainees and Level I personnel.
3) Level III- An NDT Level III individual should be capable of developing, qualifying, and approving procedures, establishing and approving techniques, interpreting codes, standards, and specifications and procedures; and designating the particular NDT methods, techniques, and procedures used. The NDT Level III should be responsible for the NDT operations for which qualified and assigned and should be capable of interpreting and evaluating results in terms of existing codes, standards and specifications.
Level III continued- The NDT Level III should have sufficient practical background in applicable materials, fabrication and product technology to establish techniques and to assist in establishing acceptance criteria when none are otherwise available. The NDT Level III should have general familiarity with other appropriate NDT methods, as demonstrated by an ASNT Level III examination or other means. The NDT Level III , in the methods in which certified, should be capable of training and examining NDT Level I and II personnel for certification in those methods
Note-ISO 9712 has a general and specific exam and each exam will have a written and a practical part
Also an eye exam should be accomplished annually for near vision acuity and every 3 years for color contrast Differentiation.
Re-certification for Level I and II should be every 3years, Level III every 5 years.(ASNT)
1) employee has proof of prior certification.
2) The employee was working in the capacity to which certified within 6 months of termination.
3)The employee is being re-certified within within 6 months of termination.
4) Prior to being examined for certification, employees not meeting the above requirements should receive additional training as deemed appropriate by the Level III.(ASNT)
1) The employer has maintained the personnel certification records.
2) The employees certification did not expire during termination.
3) The employee is being re-instated within 6 months of termination (ASNT)
1) Does the facility have a manual to include an organizational chart?
2) Does the manual contain or refer to the appropriate specifications, are they current , and available?
3) Are there provisions in the manual for internal review/evaluation and are the appropriate records maintained?
5) Are there procedures in place to revise the manual?
6) Are there procedures in place for retention of records?
7) Does the manual contain procedures that address nonconformities?
8) Are the manuals and procedures available to and used by qualified personnel?
9) Does the manual contain controls for subcontracts for NDI services?
10) Does the manual contain controls for management of NDI products, materials, and consumables?
11) Is there a separate NDI organization in the facility?
12) Does the NDI manager or equivalent have direct line authority to the NDI qualified personnel?
13) Are the NDI requirements provided to the NDI inspection personnel by use of written practice?
14) Does the NDI manager, or equivalent, review the quality assurance system to monitor compliance to the FAA approved data?
15) Are proper shift change procedures in place?
1) Is the size of the work area sufficient to perform the NDI inspections?
2) Is there adequate work area for storage and separation of NDI materials?
3) Is there a method for controlling and segregating nonconforming NDI equipment and materials?
4) Are appropriate manuals, procedures, and other documentation available for use by qualified personnel?
5) Are adequate parts handling systems (cranes, hoists, lifts etc…) available?
6) Do routing documents specify the operation needed and in what sequence?
7) Is adequate protection provided to parts during handling and routing?
8) Is metal to metal contact of finished surfaces prevented during handling?
9) Are obsolete documents removed from inspection areas
1) Is there a procedure for calibrating inspection devices to certified standards?
2) Are there procedures for segregation of functional and nonfunctional equipment?
3) Are procedures in place to ensure repaired equipment is recalibrated?
4) Are reference standards properly labeled, stored and used?
5) Are independent data available for reference standards, ie., drawings, metrology, etc.?
6) Are the calibration methods documented?
7) Do calibration methods include environment controls, standards to be used, and accuracy requirements?
8) Are setup verifications performed on all shifts as appropriate?
3) No coating that may prevent detection of surface defects. Paint or chrome greater than .003 inch in thickness, and ferromagnetic coating such as electroplated nickel greater than .001 inch
2) Pocket Dosimeter – The pocket dosimeter is basically an air- filled ion chamber.The pocket dosimeter uses a charger to apply an electric charge to zero the quartz fiber as the dosimeter is exposed to ionization radiation, the ions created will neutralize the charge on the fiber and wire causing the fiber to move toward the wire giving a reading of exposure in milliroentgen (mR). The pocket dosimeter should be calibrated every12 months.
3) Film Badge or TLD – Must be sent out monthly to a certified Lab for reading, they will send back a report of individual exposure, which must become a part of the individual personal exposure record.
4) Rate Alarm – Set to 500 mrem/hr. calibrate every 12 months, may only be required for use with isotopes.
C-scan – Is a “Plan View” presentation similar to an X-ray picture.The C-scan shows shape and location of the discontinuity but does not show depth.
1) Analog meter 2) Digital meter 3) Oscilloscope 4) Impedance plane 5) Strip chart recorders
Conductivity cont. Accomplishing a conductivity measurement is achieved by using a conductivity instrument setting it up with known calibration standards of known value. A reading is given in % IACS (International Annealed Copper Standard) These standards should be checked periodically for accuracy due some materials conductivity changes with age
