When M&TE is suspected or actually found to be inoperable, unreliable, defective,
or out of calibration, all data recorded since the previous calibration by affected
equipment shall be identified through the usage record described in Section 220.127.116.11.1
(see Appendix B). A prompt evaluation shall be performed to determine the need
for corrective action. This evaluation shall be documented on a Gross Error Report
(see Appendix D). The validity of all applications and data derived since the
previous calibration should be evaluated and dispositioned by the appropriate
owner/operator affected. The owner/operator of the affected equipment should
establish the nature and timing of corrective actions.
A maintenance history file should be kept for all M&TE. This file
should include the following, as appropriate:
manufacturer's data, including model number and serial
plant-unique identification number
calibration interval and specifications
history of calibrations, repairs, restrictions on use, and other
calibration non-conformance evaluations (Section 3.4.5)
usage record (Section 18.104.22.168.1)
non scheduled actions
Records for lost, destroyed, unavailable, or removed-from-use M&TE
should be maintained in the history file.
Manufacturer's information manuals and supplemental bulletins should
be filed in accordance with document control procedures.
