Nondestructive test equipment calibration & maintenance services

The contractor shall provide calibration and maintenance for the nondestructive equipment IAW the ASNT and NAS-410 requirements. See PWS for list of equipment. 

The contractor shall be a recognized Magnaflux® authorized service center.  The magnetic particle units shall be calibrated per American Society for Testing and Materials E1444-11 (ASTM E1444-11) requirements and the Magnaflux® specifications using National Institute of Standards and Technology (NIST) traceable standards.  Calibration of the Magnaflux® magnetic particle units shall include at a minimum:

* Ammeter accuracy of any/all ammeters used on units.

* Timer accuracy.

* Quick break check.

The contractor shall provide preventive/corrective maintenance on all magnetic particle inspection units at the time of calibration.  The contractor shall be Magnaflux® trained to service all ATC magnetic particle machines and any/all associated equipment.  Preventive maintenance shall include at a minimum:

•  Headstock, tailstock and coil mechanical operation.
• Short circuit test between the headstock and tailstock.
• Quick break function test (only on 3 phase FWDC and HWDC machines).
• Pump and fluid hose circulation, bath level, and bath concentration.
• Inspection of bath tank for foreign material.
• Pneumatic operation of the headstock (includes headstock, footswitch and air solenoid valve).
• Function of cooling fans inside the unit.
• Electrical checkout of all operating relays, timers and contactors.
• Checking physical condition of contactors.
• Physical inspection of all electrical wiring and cables.
• Operational check of all switches and controls associated with the unit.
• Any item found during the inspection is documented and corrected (if possible) during the calibration visit.

Eddy Current inspection units shall be calibrated to ASNT requirements and the manufacturer’s specifications using National Institute of Standards and Technology (NIST) traceable standards.  The frequency response over the entire range of the instrument and proper wave form will be verified.

Dye Penetrant inspection units shall be calibrated to ASNT requirements using National Institute of Standards and Technology (NIST) traceable standards.

Ultrasonic Test inspection units shall be calibrated to ASNT requirements using National Institute of Standards and Technology (NIST) traceable standards.

The contractor performing the calibration and repair services shall discuss all findings and results with the ATC TPOC before leaving the work site.
