3rd, 4th and 5th paragraph may not be applicable but 1st and 2nd are. when it comes to "calibration" of a form, "customer satisfaction survey" for example, it can be calibrated against what is the current needs of the market. obviously, this is not traceable to any national or international measurement standard. in this case, the standard one will be using is the "market needs".
if this is not valid, then what happend to clause "6.3.6. Measurement Control" of "ISO9004-2 Guidelines for Services"?
for the benefit of those who have no copy ISO9004-2 at-hand:
"6.3.6 Measurement System Control
Procedures should be established to monitor and maintain the system used for service measurement. The controls include personnel skills, measurement procedures and any analytical models or software used for measuring and testing. All measuring and tsting, including customer satisfaction surveys and questionnaires, need to be tested for validity and reliability. The use, calibration and maintenence of all measuring and test equipment used in providing or assessing services should be controlled to provide confidence in decisions or actions based on measurement data. Measurement error should be taken when precision and/or bias requirements are not achieved."
