VISUAL INSPECTIONS AND INTERCOMPARISONS
12. Purpose. This
section provides guidance and
procedures applicable to visual
inspections and intercomparisons of measurement standards.
13. Applicability. This
section is
applicable to
TSAs and ARNG that
ship, or
transport,
their measurement standards to another calibration activity, not located in the same
building, for calibration support.
a. Visual Inspection
(1) A visual inspection will be performed on measurement standards that are
received from another calibration activity. These inspections are performed to assure
that standards have not been damaged or degraded during transportation. Visual
inspections are required as follows:
(a) All measurement standards will be visually inspected upon return from
the supporting calibration activity.
(b) Visual inspections will be sufficient to assure that no physical damage
occurred during shipment which would impair operation of the standard or degrade its
measurement capabilities. When a visual inspection indicates that a possible out-of-
tolerance condition exists, reliability checks will be performed when the capability to
make such measurements exists. If the capability does not exist, the item will be
returned to the supporting activity.
(c) A check will be made to ensure all labels and forms have been annotated
properly.
(2) Records
(a) Data resulting from visual inspections will be recorded on the reverse
side of the calibration test report, or in a separate logbook. When a calibration report is
not furnished, data will be recorded on a separate record. As a minimum, data will
include: date of visual inspection, condition of standard, and initials of person
performing inspection. When damage is observed, a short narrative explanation of the
damage, suspected cause, and corrective action taken will be recorded.
