4.5.5 Functioning.

4.5.5.1 Impact sensitivity primer. The sample units shall

be mounted in a test fixture. The primer shall be impacted on

centerline with a 1.94 � .02 ounce firing pin with a tip of

approximately .100 spherical diameter, impacting at 8.7 fps (14

inch drop) maximum. Statistical data shall be gathered to show

8.7 fps to be greater than the mean velocity plus 4 sigma

deviations.

4.5.5.2 Pressure/time values. Sample cartridge assemblies,

Dwg . 9366511 shall be selected in accordance with 4.4. The

samples shall be assembled to a closed bomb type test fixture and

the pressure/time values shown in Figure 1 shall be demonstrated

by functioning the pressure cartridge.
