“Calibration” is the act of comparing a measuring device to a standard. ISO 9001 requires traceability of standards. Calibration may or may not involve adjustment. ISO 9001-2000, 7.6 says, in part, that measuring equipment shall…
There is no explanation given for the difference between “calibrated” and “verified” in this context. In either case, the requirement for traceable standards applies, (unless no traceable standard exists) so there is no substantive difference between the two.
Calibration - a set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system or values represented by a material measure or a reference material, and the corresponding values realized by the standard.
NOTES
1 The result of a calibration permits either the assignment of values or measurands to the indications or the determination of corrections with respect to indications.
2 A calibration may also determine other metrological properties such as the effect of influence quantities.
3 The result of a calibration may be recorded in a document sometimes called a calibration certificate or a calibration report. (International Vocabulary of Basic and General Terms in Metrology)
