minimum, the spring shall be measured and the measurement shall
be compared to the original free length to ascertain compliance
with the specified requirement. Any spring that fails the
requirement shall be classed defective. One defect shall be
cause for lot rejection.
4.5.5 Check test for deterioration of detonators. If the
total time between original acceptance of any detonator lot and
the assembly of that lot into the fuzes exceeds two years, at any
time since previous tests, the detonator lot shall be subjected
to and must satisfactorily pass the functioning and output tests
specified in MIL-D-45495 immediately before the detonator lot is
assembled into the fuzes. The test shall be performed by the
contractor on detonators randomly selected by a Government
Inspector. The test shall be conducted at Government expense
without cost to the contractor who loaded the detonators or the
contractor who is to assemble the detonators into the fuzes. The
test shall not constitute a basis for fuze lot rejection against
either contractor except where deterioration has occurred as a
direct result of carelessness in handling, storage, etc.
permitted while the detonator lot was under the jurisdiction of
the contractor.
4.5.6.1 Load test of No. 1 gear and pinion assembly. Apply
the required axial load perpendicular to the No. 1 gear and in
such a direction as to test the assembly of the No. 1 gear and
pinion. The required force shall act against the No. 1 gear.
Upon removal of the required force, the maximum permissible gap
shall be inspected for compliance with the drawing requirement.
Any No. 1 gear and pinion assembly that fails the requirement
shall be classed defective and removed from the lot.
4.5.6.2 Load test of NO. 2 sear and pinion assembly. Apply
the required axial load perpendicular to the No. 2 gear and in
such a direction as to test the assembly of the No. 2 gear and
pinion. The required force shall act against the No. 2 gear.
Upon removal of the required force, the maximum permissible gap
shall be inspected for compliance with the drawing requirement.
Any No. 2 gear and pinion assembly that fails the requirement
shall be classed defective and removed from the lot.
4.5.6.3 Load test of escapement gear and pinion assembly.
Apply the required axial load perpendicular to the escapement
gear and in such a direction as to test the assembly of the
escapement gear and pinion. The required force shall act against
the escapement gear. Upon removal of the required force, the
maximum permissible gap shall be inspected for compliance with
the drawing requirement. Any escapement gear and pinion assembly
that fails the requirement shall be classed defective and removed
from the lot.
