4.5.2 Moisture content of barium nitrate. The moisture content of
barium nitrate shall be determined at the time of loading. The method
shall be in accordance with MIL-STD-650, Method 101.5. The sample shall
be selected from that quantity to be used to produce a primer lot and
shall meet requirements of the applicable drawing. If the moisture
content fails to comply with specified requirement of 3.3.1, the batch
shall be rejected.
4.5.3 Moisture content of lead azide. The moisture content of lead
azide shall be determined as specified in 4.5.2, except that a two gram
sample shall be used and the dish covered with a sheet of
polytetrafluoroethylene.
The sample shall be selected from that quantity
to be used to produce a primer lot and shall meet the requirements of the
applicable drawing. If the moistdure content fails to comply with
specified requirement of 3.3.2, the batch shall be rejected.
4.5.4 Functioning tests - Sensitivity and output. The battery
primer samples selected from each inspection lot shall be assembled to
the applicable test fixture (see 4.4.5.1) and subjected to a no-fire test
followed by an all-fire output test.
4.5.4.1 No-fire test (70 10F). The battery primers shall be
conditioned at 70 10F for two (2) hours minimum (min.) prior to
function test. The battery primers shall be assembled to the applicable
test fixture (see 4.4.5.1) and subjected to a constant 10 ma current for
10 seconds min. to determine conformance with 3.4.1.1. Any primer which
fails to comply with the applicable requirement shall be classed
defective.
(Non-destructive test).
4.5.4.2 All-fire output test (70 10F). Following the
No-fire test of 4.5.4.1, the battery primers shall be fired by applying
the energy from a 100 microfarad capacitor charged to 1.6 volts max.
Observation shall be made for failure to comply with requirements
specified in 3.4.1.2. If any battery primer fails to meet the output
requirements on the first attempt, it shall be classed defective.
(Destructive test).
4.5.5 Environmental tests.
