I would not include a section abut R&R, but certainly would about measurement uncertainty.....
For a calibration to be considered traceable, two things are required: (1) an unbroken chain of comparison to National or international standards; and (2) stated uncertainty at each step.
The unbroken chain will only require documenting the link to the calibration standard by including the description or number of the calibration standard, its next calibration due date, and the certificate number from its last calibration.
The uncertainty can be calculated for the type of application or for each specific calibration.....I would examine how many of the calibrations are to be done in order to decide which to do.
The uncertainty tells you how much error exists in the calibration and what the error is.....it includes the calibration standard, the instrument being calibrated, environmental conditions, and any other influences that might affect the measurement.
As for procedure steps, I would start with a visual and functional check of the instrument; required items to effect the calibration; connections or similar; the specific tasks to effect the calibration; documentation including traceability and uncertainty.
Also, obtain a copy of The Metrology Handbook, available from ASQ.
Hope this helps.
