This monitoring will be performed on a work day at an hour nearing the close
of the working period.
The procedure for taking particle samples will be
furnished by AMCC.
AMCC may authorize local taking of samples and making
particle counts when equipment is locally available. Extensive testing has
shown that particle size distribution can be standardized. Particle samples
submitted to AMCC for particle count will undergo a microscopic inspection
of a statistical sample of the effective filter area to determine the
quantity of particles per cubic foot larger than 5 microns. Samples found
to contain fewer than 5.3 x 103 particles larger than 5 microns per cubic
foot shall be considered as satisfactory evidence that the sampled
environment meets the dust particle limits.
(d) Action. A dust particle count greater than that specified in
a(3) above will not automatically invalidate any calibrations already
performed.
Corrective measures, however, are to be taken immediately to
bring particle contamination under control.
(3) Lighting.
(a) Interval.
At discretion of the laboratory chief.
(b) Instrumentation.
No lightmeter will be furnished the
secondary reference laboratory for this purpose.
Lighting surveys and
maintenance are the responsibility of the post engineer.
Survey results
will be recorded and filed as for other environmental data.
Should this
service not be available, inform AMCC and request instructions.
(1) Charts for the temperature and humidity recorder will be dated
and filed in chronological order. These charts will be retained for 1 year
and will be the backup data to justify the administrative action taken and
will be documented in a logbook.
(2) Recorded deviations from environmental conditions will be
investigated and analyzed with subsequent action.
Out-of-tolerance
conditions and the appropriate action will be recorded in a laboratory
logbook and maintained for a period of 1 year to run concurrently with the
associated environmental records.
A laboratory logbook, permanently bound
and pages sequentially numbered by the printer, will be kept for each
laboratory.
A new page will be used for each calendar day an out-of-
tolerance condition occurs. The following information must be entered into
the logbook:
(a) Identification of laboratory where environmental deviation has
occurred.
(b) Date and time of deviation.
(c) Duration of deviation.
