I. Calibration will be performed in accordance with MIL-STD-45662.

II. All inspection, measuring, and test equipment shall be inspected and calibrated against certified standards. These standards are traceable to NITS/NBS . the measurement standard accuracy shall be more than a 4 to 1 ratio to the gage being calibrated. The calibration shall be repeated at established intervals to insure continued accuracy.

III. Each piece of equipment, tools, and gauges shall be assigned a number designating its individual identity and a record for each piece will be maintained indicating date calibrated, the next due date, and the initial of the person who performed the calibration.

IV. The miscellaneous linear measuring equipment shall be calibrated at the frequency listed herein.

Measuring Devices
Micrometers, all types and sizes	180 Days
Vernier Calipers, all	180 Days
Height Guages, all	180 Days
Guage Blocks, all	2 Years
Surface Plates, all	2 Years
Angle Plates, all	2 Years

A. A recall system is used to insure that the calibration per above is adhered to. A metal file box (containing tabs for each month) is used to store the Equipment Calibration Record Cards. These cards shall be filed in the month calibration is due and the current month shall be checked at the first of each month.
B. Detailed procedures for calibration of the measuring devices are given in Appendix B. The calibration room temperature and humidity will be monitored as prescribed in these procedures.

V. When inspection and test equipment is found to be out of calibration, Quality Assurance will document the finding and notify management immediately. If it is determined by Quality Assurance that defective parts have been shipped, management will notify the customer of the possible discrepancy and make arrangements for disposition of the nonconforming items.

VI. The equipment found to be out of calibration will be removed from use and recalibrated (R4C3) and tested for accuracy. Equipment too large to be moved will be tagged with a red tag “Do Not Use”. If the equipment cannot be calibrated and has any previous record of discrepancy, it shall be discarded and its calibration card removed from the file and marked as a discrepant tool and an out of calibration tool.

VII. Equipment that has been dropped or mishandled will be recalibrated for accuracy, also frequency of calibration shortened until deemed necessary to reestablish accuracy.

VIII. Equipment Calibration Records are kept and shall be reviewed at each re-calibration. Trends or drifts can thus be ascertained and calibration intervals can be shortened as necessary.

IX. If any measuring equipment is moved or transported, adequate cases, packing and protection shall be provided to insure their protection and continued accuracy.

X. Calibration of outside calibration sources measuring equipment will be insured by mail. This will be done yearly.

XI. An internal self audit will be conducted yearly in December to assure that all internal quality functions are being performed.

XII. If production tooling (molds, jigs, fixtures, etc) are being used in the manufacturing process, An inspection of the first and last piece manufactured will be made to assure no change in the tooling status. At present, it is not planned to use production tooling as medium of inspection.
