xstm This or other required calibration intervals shall be approved by the authority. The above checks are minimum and do not relieve the responsibility of constantly checking and immediately repairing any item which may affect test results. A history of the repairs, modi? The manual shall include the maintenance procedures and schedules for each type of equipment and the calibration schedule of each type of equipment.
It should be available for the guidance of the technician. The manual shall include: They should include the following minimum information: A procedure for auditing of reports by Level III personnel must be included.
When personnel leave the agency, the records may be transferred aztm an inactive? The company does not have to possess codes and speci? Others may be simply utilizing only manual application of a basic instrument.
Section 2 provides a list of documents which include speci? Either a-c or d-c fullwave or half-wave recti? After proper cleaning of the part, the magnetic particles may be applied either wet or dry.
It is a U-shaped iron core with a coil around the cross bar or a U-shaped or? The yoke is normally operated by line voltages or V. It is a current-carrying conductor formed into a coil of several turns. They are rods, normally 1? The ends of a pair of prods are placed on the part and current passed from one prod to the other through the part.
They are spring-loaded clamps with braided copper pads on the inside of the jaws. The clamps are clamped onto the part and a current is passed from one clamp to the other through a part. They are braided copper or lead pads placed at each end 6 of the part. Current is passed from one pad to the other through the part.
Pads are normally used with stationary equipment and rigged so that the pads are in contact with the part under pressure. Therefore, equipment must be available to transform line current and, when required, to rectify it. The equipment should contain an ammeter to indicate the magnetizing amperage, suitable switches, and, when required, timers to control the length of time that the current is applied. If different amperages are required, the equipment shall produce the maximum required amperage with a suitable control for reducing the amperage to the required lower levels.
Cables should be of adequate but not excessive length and large enough to carry the required amperage.
Dry particles should be applied uniformly with a dusting or light blowing action. Wet atm should be applied by aerosol cans or by hosing. Provisions should be available to ensure that the required amount of particles are in suspension when the spray is applied and to periodically check the concentration of the solution.

Adequate white light must be available when viewing visible dyed particles and should be available for use, as needed, when viewing? Demagnetization is normally accomplished by stepping down a-c or d-c voltage while the direction of the d-c is changed between each step, or by withdrawing the part from an a-c?
Demagnetization can be accomplished by induced? Facilities should include a coil, cables when required and equipment to produce adequate voltages and e534, reversing and stepdown switches, and a meter to aetm residual external magnetic? Either X-rays or gamma rays may be used unless otherwise speci?

Different isotopes emit gamma rays in a speci? The isotope size, energy level, and strength should be selected in view of the application material, thickness, required image quality indicator, sensitivity and a reasonable exposure time.
Also, lead sheet, shot, or leaded rubber should be available to control or reduce scattered e5433. They must e43 made from material that is radiographically similar to, and that represents the speci? Blocks shall be available on which the Aatm can be placed during the exposure, if required. The thickness of the blocks should be approximately equal to the thickness of the sections being radiographed and radiographically similar. Lead numbers and letters of adequate size and thickness should be available for?
There should be a sufficient number of each letter and number to put all required identi? However, alternative methods of s543 Examples are light box exposures and permanent white ink.
Film, or paper if permitted, should be stored in a cool, dry place that is completely protected from direct or scattered radiation background radiation excluded. Various types of intensifying screens are used in industrial applications, with the most common being lead compound or lead oxide and? When intensifying screens are employed, they should be clean and free of scratches, wrinkles, surface contamination, and any other conditions that may asmt with the production of a quality radiograph.
The darkroom should be equipped with both safe and white lights and a work area to handle the? The viewing equipment should include both high- and normalintensity lights or separate viewers.
A light transmission-type densitometer should be available to measure? Other standards or Method E, or combinations thereof, should be used as appropriate to verify sensitivity and beam quality.
The source aperture or other method of collimation must be well de? The neutron source may be a reactor, accelerator, or radioisotope provided the requirements of the speci?
