6.2.4 Detailed packing and marking instructions. (see 5.1 and 5.2)
6.2.5 Provision for the supply, maintenance and disposition of mandatory
ballistic test equipment for acceptance inspection purposes.
6.2.6 Provision for the submission and approval of the manufacturing
process. (see 3.3)
6.2.7 Instructions for shipment of first article lot sample for firing test.
6.3 Process Deviation.-A process deviation is defined as a change in the
approved basic method of manufacture or an operational change which may
alter the metallurgical or physical properties of the item.
6.4 First Article Sample.-In order to minimize inspection costs, the
firing tests of 4.4.4 will be performed after the sample has been provision-
ally accepted by the Government for all other requirements. Additional
cartridges may be required by the testing facility.
6.5 AQL's. -The optional use of AQL values for either individual defects
or classes of defects, with individual major defect limitation, is intended
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.
6.6 Combining Tests. -With approval of the procuring activity, tests may be
performed concurrently on the same sample cartridges provided that the
test results are not effected by this procedure. The test facility should
make maximum use of this procedure in order to minimize testing costs.
6.7 Contamination of Explosive Components .-Particular care should be
exercised to avoid contamination of primers and propellant by oil, grease,
or other foreign matter since such contamination can cause misfires, in-
crease action time and lot rejection.
6.8 Computations.
6.8.1 Standard Deviation. - Where computation of a sample standard deviation
is specified for determination of lot acceptance, the method of computation
will be:
or equivalent.
