Control of inspection and measuring equipment is an element of the quality management that is more important than ever before. The introduction of the ISO 9000 family of international standards has led to major changes in this field as well. Among other things, ISO 9001 specifies that :
«all inspection and measuring equipment than can affect product quality must be identified, calibrated and adjusted at prescribed intervals, or prior to use, against certified equipment having a known valid relationship to internationally or nationally recognised standards».
This standard also states that the supplier shall :
«ensure that the inspection and measuring equipment is capable of the necessary accuracy and precision».
