6.1.4 Instructions for shipment of first article and production samples
for firing tests.
6,1.5 Provision for furnishing the National Stock Number (NSN) if packing
and marking for shipment is required. (see 5.1 and 5.2)

furnished equipment for acceptance inspection purposes.

6.2 First article sample. -In order to minimize inspection costs, the firing
test, as specified in 4.3, will be performed after the sample has been
found acceptable for all other requirements.

or classes of defects, with individual major defect limitations, is in-
tended to minimize inspection agency administrative burden which might
result from an exclusive assignment of individual defect AQL's. The
option also permits flexibility where sampling inspection for acceptance
is integrated into the manufacturing process.
