Instruments used on sy stems that contain oil, brackish
water, etc., should be identified clearly to avoid
contamination of other sy stems. For example an oil-
contaminated gauge should not be used on an oil-free
compressed air sy stem, or a saltwater gauge should not
be used on a sy stem containing process liquids.
Issue of M&TE for use
Issuing of M&TE should be conducted utilizing a
usage record. (See Appendix B.) The M&TE should
have a usage record filled out to identify each item
calibrated or tested by that M&TE. A new usage
record should be initiated each time the M&TE is
calibrated, and the previous record should be retained
in the maintenance history file. The usage record for
each item of M&TE should be retained in the issue
Test equipment whose calibration has expired may be
used only with written request from the operations
manager and approval of the standards laboratory
manager. If this situation occurs, the test equipment
shall be calibrated as soon as feasible.
calibration data reflect out-of-tolerance values, the
maintenance performed with this test instrument shall
be evaluated (see Section 3.4.5). M&TE with an
expired calibration should be identified by a "rejected"
sticker and placed in a location to satisfy Section
188.8.131.52.1 of this procedure.
The control process used for M&TE should be a well
established Recall Program containing, as a minimum
the following controls:
Total inventory listing
Calibration DUE notices - weekly
Calibration OVERDUE notices - weekly
