4.5.6 Cartridge stripping. A dummy (M232) cartridge shall be
inserted into each test link and the linked cartridge shall be
assembled into the test fixture. A gradual force shall then be
applied on the base of the cartridge until the cartridge is
completely stripped from the link. The force required to strip
the cartridge shall be measured and a determination shall be made
for compliance with the requirements of para. 3.4.
*
4.5.7 Disassembly torque. The sample links shall be
assembled with cartridges into a belt with a minimum of five (5)
links and cartridges and placed in the approved test fixture. A
gradual torque shall be applied to the first cartridge until it
separates from the belt. Record the maximum torque value and
determine compliance with para. 3.5. A linked belt of at least
five links shall be maintained at all times. Testing shall be
repeated until all sample links are tested.
4.5.8 Belt strength. The links shall be assembled into belts
of six links with six dummy (M232) cartridges and placed in the
test fixture. The load shall be applied at a uniform rate and the
belt shall remain under tension for a minimum of thirty (30)
seconds. If any link in any belt separates the belt shall be
rejected. The sample links used for this test shall not be
returned to the lot.
4.5.9 Assembleability and free hinge. The sample links shall
be assembled into 200 round belts using dummy (M232) cartridges.
Each 200 round belt shall be laid out horizontally to its full
length, with the open side of the link up. One end of the link
shall be drawn upon the remainder of the belt until the belt is
completely reversed (open side of the links down). One end of the
reversed belt shall then be drawn back upon the remainder of the
belt until the belt is returned to its original position (open
side of the links up).
4.5.10 Dynamic requirements. The links shall be assembled
into belts of one hundred one (101) links with one hundred dummy
(M232) cartridges and placed in the test fixture. The end of the
belt with the free front and rear loops shall be placed on the
test equipment with the cartridge bases facing the operator.
Assuring no movement of the belt prior to the test, the free end
of the belt shall be allowed to drop freely. If partial or full
separation is found in any area of the belt other than the ten
(10) links from the free end the lot shall be rejected. Partial
separation is defined as any disengagement of the link's front,
rear or middle loop with the cartridge.
