(3) Defective assembler's lots will be segregated from grand lots and
inspected individually when one or more of the following occurs:
(a)
A Major A defect is found in an assembler's lot.
(b) The Major B or Minor defects found seem to be concentrated in one
or more (a small subset of lots) of the assembler's lots comprising the grand lot.
(c) The inspector determines for any reason, based on initial inspection
results, that inspection of an individual assembler's lot is justified.
(4) Grand lotting is encouraged (to conserve resources) whenever it is
considered appropriate by the inspection activity. Grand lotting will not be used when
performing warranty inspections or on inspections of lots reported as possibly having
wholesomeness deficiencies.
c. STEP 3: Inspect Shipping Containers.
(1) In accordance with Table A, Sampling Criteria for Normal Inspection of
Shipping Containers (Nondestructive CPI) (Table 4-1) select the appropriate sample
size for shipping container examinations. Obviously damaged shipping cases should
not be selected unless they are truly representative of the lot. Damaged cases should
be set aside, inspected and salvaged.
(2)
Routine inspections will be conducted using a single sampling plan.
(3) Using the defects listed in Table E, Defects for Shipping Containers
(Table 4-5) the inspectors should check each sample case for previously opened boxes.
While this may indicate tampering, it may also be due to other reasons (for example, a
wholesale rework of a lot). Inspectors should contact their supervisors for guidance if
pilferage or tampering is suspected. Also, observe each case for signs of rodent
damage or insect infestation. Post the infestation findings on the inspection report, to
include:
(a) Whether or not the pests were alive or dead.
(b) Identification of the pests (based on entomological or laboratory
identification).
(c)
Probable origin of pests (DSCP Handbook 4155.2, paragraph XI).
(d) Probable movement of pests. For example, from outside the
shipping container into the modules or vice-versa.
(e) Classify each defective case by the most serious defect it
possesses.
