Hello,

I am looking for opinions and interpretations of the calibration
requirement for section 4.11, Control of Measuring and Test Equipment, of
ISO 9002. I contend, that by the strictest interpretation of the standard,
(not necesarily best practice) that as a manufacturer of PCBs, we need only
control and calibrate measuring and test equipment used to measure or test
product.

Example: Calipers must be calibrated because they are used to measure
product to demonstrate conformance to specifications, Plating tank
rectifiers need not be calibrated because they are not used to measure
product conformance.

And, paragraph one of section 4.11 reads as follows:
" The supplier shall establish and maintain documented procedures to
control, calibrate and maintain inspection, measuring and test equipment
(including test software) used by the supplier to demonstrate the
conformance of product to the specified requirements...."

Now, dont get me wrong, we do calibrate our rectifiers (best practice) and
like equipment. I simply contend that the calibration of equipment, other
than equipment that is used to demonstrate PRODUCT conformance, is beyond
the scope of the requirement (ISO 9002).

Sooooo, opinions anyone??
