4.4.2 Sampling.
4.4.2.1 For nondestructive tests. Unless otherwise specified in the applicable test method, sampling for and
evaluation of nondestructive inspection shall be in accordance with MIL-STD-1916, variable sampling for
normal inspection, verification level V, single or double specification limit (as applicable).
4.4.2.2 For destructive tests. The ballistics LAT sample for the igniter lot shall be selected and evaluated in
accordance with ANSI/ASQC Z1.9, normal sampling plan, inspection level S4, for each temperature tested.
The destructive test shall be evaluated and accepted in accordance with ANSI/ASQC Z1.9, standard
deviation method, single or double specification limit (as applicable), variability unknown. In the event of
static-firing failure, the sample firings will be terminated for the remaining sample units pending disposition
instructions from the procuring activity.
4.4.3 Classification of characteristics. The characteristics verified by the tests and examinations herein are
classified as critical, major, or minor in accordance with DOD-STD-2101 Requirements that verify critical
characteristics are identified by the symbol (C) and major characteristics by the symbol (M). The number
following the classification symbol indicates the serial number of the requirement. Requirements which are
not annotated with a classification code are classified minor.
