Does the requirement to indicate the status of calibration apply to devices such as a TCLP tumbler? Although we check the rotational rate monthly, there does not seem to be any adjustment on this device.

Some support equipment have no "calibration" and would seem to be exempt from this regulation.


(Quality System Expert Committee/NELAP Accreditation Councel, x-x-10)

The cited section is preceded by "Whenever practicable". If a piece of support equipment does not require a calibration, it cannot require a notification of calibration status. It may, however, have an indication of the verification of its effectiveness (e.g., such as a date when the number of revolutions per minute on a TCLP tumbler was verified).
