AS9100 Monitoring Measuring Resources Control Procedure
The Control of Monitoring Measuring Resources Procedure AS9001 establishes methods for using aerospace calibration equipment, and maintaining monitoring and measuring devices, as well as associated quality record-keeping. The procedure applies to aerospace personnel performing measurement systems analysis, monitoring and measurement activities, and the monitoring and measuring devices needed to provide evidence of conformity of product to determined requirements.

Monitoring Measuring Resources Control Procedure AS9100 Responsibilities
The Quality Management is responsible for the measuring instrument (device) calibration program.
The Purchasing Manager and the Quality Assurance Manager are responsible for ensuring subcontractor monitoring and measuring systems are adequate to assure compliance with safety and quality requirements.
All Employees are responsible for verifying that instruments they use to monitor processes or measure items are within their calibration periods and for ensuring that such instruments are capable of measuring to required accuracy/tolerances.
AS9100 Monitoring Measuring Resources Control Procedure Definitions
Calibration – Comparison of a measurement standard or instrument of known accuracy with another standard or instrument to detect, correlate, report, or eliminate by adjustment any variation in the accuracy of the item being compared.
Calibration period – Period during which a certified calibration is valid (e.g., measuring equipment calibrated in March and certification expires in March of next year, calibration period = twelve months).
Gage R&R – Gage Repeatability and Reproducibility study determines whether the employees are consistent in their measurements of the same part (repeatability) and whether the variation between employees is consistent (reproducibility). Usually consists of 3 appraisers, measuring 10 randomized samples, and 3 trials for a total of 270 measures.
Measurement Systems Analysis – MSA determines the variation present within the measurement system that may influence measurement outcomes. Various factors are considered including: accuracy/bias, resolution/discrimination, linearity, stability, gage R&R.
Monitoring – Routine measurement or observation of monitoring/ measuring equipment, to check its functionality.
Monitoring and measuring resources – People and devices used to collect data and measure, gauge, test, inspect, or otherwise examine items to determine their compliance with specifications.
Reference standard – Standard of the highest order of accuracy in a calibration system, establishing basic accuracy values for that system; typically traceable to a recognized standards body like NIST (USA) or INMS (Canada).
Traceability – The ability to relate individual measurement results to national standards or nationally accepted measurement systems through an unbroken chain of comparisons.
Working standard – Designated standard used in calibration as a medium for transferring the basic value of reference standards to lower echelon measuring and test equipment.
