MIL-D-70436(AR)
contents shall be dried in an oven maintained at 60 degrees C plus
or minus 5 degrees C for 30 minutes, cooled in a desiccator and
weighed.  The loss in weight shall be calculated as the percentage
of tetracene in the sample on a dry basis as follows:
where:
D = Weight of crucible and sample after treating with hot
water.
E = Weight of crucible.
W = Weight of sample.
M = Moisture content of sample obtained in 4.5.3 in percent.
4.5.5.5 Lead azide.  The lead azide content in the sample of
a dry basis, shall be determined by subtracting from 100 the
combined percentages of barium nitrate, lead styphnate, tetracene
and antimony sulfide.
4.5.6 Functioning.
4.5.6.1 Sensivitity and output.  The sample detonators shall
be randomly selected from each lot.  The detonator shall be
assembled with lead 11834335 in accordance with drawing 11834340.
A weight of 0.25 ounce plus or minus 0.01 ounce shall be dropped
on the firing pin, to function the detonator, from a height of
five (5) inches maximum.  The height of drop shall be measured as
the height from the top of the firing pin to the bottom of the
weight.  A detonator that fails to fire shall be classed
defective.  A detonator that fires but fails to initiate the lead
sufficiently to produce a dent in the steel witness block of the
required depth shall be classed defect if the detonator
confinement sleeve expansion is 0.330 inch diameter or greater.
If the confinement sleeve expansion is less than 0.330 inch
diameter, the detonator shall not be classed defective, but the
detonator classed defective and the result of a no-test.  The
indentation depth shall be measured using a probe with a 0.017
inch plus or minus 0.002 inch spherical radius tip.
4.5.6.2 Varicomp initiation.  The sample detonators shall be
randomly selected from each lot.  The detonator shall be assembled
with test lead 11834345 in accordance with drawing 11834340 and
functioned as in 4.5.6.1.  A detonator that fails as specified in
4.5.6.1 shall be classed defective.  The indentation depth shall
be measured using the probe specified in 4.5.6.1.
