4.5.16 Temperature conditioning. After verification of the
safe condition of 4.5.19, the test items from 4.5.15.3 shall be
subjected to continuity resistance measurement of the circuits
containing detonator(s), micropiston actuator and common ground
as per 4.5.14. The test items shall then be temperature
conditioned at the prescribed temperature for two (2) hours min.
(See 3.6).
4.5.17 Arming of S&A assemblies.
Arming will consist of the
following:
Initial arming will consist of displacing & locking
a.
the two centrifugal locks.
b.
Final arming will consist of firing micropiston
actuator and displacing slider release pin.
4.5.17.1 Initial arming of S&A assembly. The S&A test
samples form 4.5.16 shall be placed In an approved fixture and
spin machine and subjected to a spin of 3160 + 290 RPM above its
center line, as noted on the applicable drawing. While at this
RPM, the lock plate shall be impacted with required minimum force
to lock both centrifugal locks at the armed position.
4.5.17.2 Final arming of the S&A assemblies. The sample S&A
assemblies form 4.5.17.1 shall be prepared for remote final
arming (See c, f) and functioning (See a, b, c, d, f):
a.
An aluminum witness plate shall be secured at the
end face of MDF cap preselected for functioning.
(Dwg. 9328756 only)
b.
A confining steel cylinder shall be placed around
the S&A shield to provide a witness surface for
each of the four (4) main explosive leads. The
cylinder shall be secured to preclude unwanted
displacement.
c.
The S&l+ assembly shall be wired for remote
initiation of the micropiston actuator and
detonator(s).
d.
Temperature conditioning of the sample S&A
assemblies shall be continuous until five (5)
minutes before functioning.
