4.3.3.2.7.2.2 Explosive graze functioning (see 3.7). The fifty
(50) fuzes previously tested in 4.3.3.2.7.2 and 4.3.3.2.7.2.1 shall be
subjected to the test specified in 4.4.10 using test equipment specified
in 4.3.4. The lot shall be rejected if two (2) or more fuzes are classed
defective according to the defects defined in Table II (see 4.3.3.1.7.2.2).
Fuzes which do not function shall not be included in the calculations for
average graze functioning level and outliers are not permitted. Refer
to 6.6 for calculation of sample standard deviation (sigma).
4.3.3.2.8 Check test for possible deterioration (see MIL-P-14137
and 6.5). If the total elapsed time between the original acceptance of
any initiator lot and the assembly of that lot into the fuze exceeds
two years, or if the initiators have been subjected to adverse conditions
for any period of time since previous tests, the initiator lot shall be
subjected to and must satisfactorily pass the check test for possible
deterioration required by the initiator specification immediately before
the initiator lot is assembled into the fuze. These tests shall be
performed by the contractor on initiators selected by the Government
inspector at the facility assembling the initiators into the fuze. The
test shall be conducted at Government expense without cost to the contractor
who loaded the initiators or the contractor assembling the initiators
into the fuze and shall not constitute a basis for rejection against
either contractor except where deterioration has occurred as a direct
result of carelessness in handling, storage, etc., permitted while the
initiator lot was under the jurisdiction of either contractor.
4.3.3.2.9 Heat seal test of sealed bag (see dwg. 8798862) -
Major defect- Code no. 17002. Sampling, acceptance criteria and
test procedures for this test shall be as required in MIL-P-116
(Preservation, Methods of). This test is applicable only when
level B packing is required.
4.3.3.2.10 Determination of moisture content.
4.3.3.2.10.1 Lead azid (see 3.13.1) - Major defect - Code No. 27001.
The moisture content of the lead azide shall be determined for each lot
at the time of loading. A sample of 2 grams shall be selected and tested
as specified in 4.4.11. If the moisture content is in excess of the
specified percentage and loading has not begun, the lot of lead azide
shall be rejected until proper corrective action has been accomplished
as verified by successfully repeating the moisture content test as specified.
If loading has begun, action on the unloaded lead azide shall be as
specified above and all detonators loaded previously from the same lot
of lead azide shall be rejected. The contractor shall maintain adequate
records to provide identification of the lead azide used in the loaded
detonators.
