4.6.5 Proof loads. The proof loads of 4.6.13.1.1, 4.6.13.2, 4.6.13.4, and
4,6.13.6 shall be applied to the survival kit container. The survival kit con-
tainer shall then be subjected to and pass one test each as specified in 4.6.3.1
and 4.6.3.2 and shall be visually inspected. There shall not be any damage or
permanent deformation to the survival kit container.
4.6.6 Lid retention
4.6.6.1 Lid locking machanism. The lid shall be subjected to an upward load
of 700 pounds normal to the lid at the center. The load shall be applied to a
cable or webbing threaded through a hole or slot in the lid and attached to a
6-inch-diameter metal plate that bears against the underside of the lid. The
test shall be repeated with the load applied 3 inches to the right of the center
point and then 3 inches to the left of the center point. There shall not be any
evidence of failure of the lid locks or damage or permanent deformation. The
survival kit container shall then be subjected to and shall pass one test each
as specified in 4.6.3.1 and 4.6.3.2.
4.6.6.2 Aft compartment lid. A load of 250 pounds shall be applied to an
upward direction normal to the aft compartment lid and 1 inch forward of the
lock. The load shall be applied to an eyebolt fastened to the aft compartment
lid with a washer to bear on the undersurface of the aft compartment lid, The
aft compartment lid shall not separate from the aft compartment, become unlocked}
or show any evidence of damage or permanent deformation.
4.6.7 Fiber glass container. Four coupons of the fiber glass material shall
be taken randomly from the basic container and tested in accordance with the
applicable methods of FED-STD-406 to determine compliance with the requirements
specified in 3.4,2.1.
4.6.8 Parachute opening shock. The survival kit container shall be subjected
to simulated parachute opening shock by means of a drop test. The drop test
shall consist of dropping the loaded survival kit container to the end of a
suspension assembly of such height and elasticity as to give the required shock.
The survival kit container shall be loaded with ballast, simulating survival
equipment, to achieve a total weight of 50 pounds. The loaded survival kit
container shall be secured at the parachute attaching hardware cm both sides to
a webbing assembly (simulating the parachute harness} which, in turn, is attached
to a drop cable. The length and elasticity of the drop system shall be such as
to achieve a force of at least 30 G (peak) and a minimum rate of increase of
500 G per second between the webbing assembly and the drop cable. Following
this test, the survival kit container shall be operated to determine compliance
with 4.6.3.1 and 4.6.3.2.
