This is an interesting take on calibration, I must say! Comments any one?

I respectfully disagree. The company I am the Management Rep. for builds "Hard Tools" for metal stamping. Our customer gives us a blueprint for the part they want the tool to produce. They tell us they want it to be able to produce "X" amount of parts per hour, and they expect the product life to be "X" amount of parts. We design the tool based on that input. Hard Tool designs can take into account many variables, and with minor changes from one lot to another in material hardness, tensile strength, and the "chaos" factor, it is an inexact science (tool designers may disagree, but for the sake of argument, let's continue) . The First Article report generated from measurements taken from an actual part that has been produced by the hard tool. The First Article measurements are made using calibrated equipment. The acceptance of our hard tool is based on the First Article report.
So, the measuring and test equipment of the hard tool designers and the people making the hard tool is not calibrated. The tools (4.11.1) "used by the supplier to demonstrate the conformance of product to the specified requirements" are calibrated.
Obviously, one can question if it makes good business sense to not calibrate the toolmakers measuring equipment, but since they don't use them for final approval of the hard tool...
This application of this interpretation has passed ISO9001 scrutiny (so far).
OK, take aim and let me have it.

Yes! We are principally a design firm with no manufacturing at this point. Underwriter's Laboratories has required calibration records, i.e. certificates, recall data, etc. on all instruments, including a tape measure. Our technicians and design engineers must keep accurate records of calibration.
