MIL-PRF-29504/5D
21. For style 1 and 3 terminus only, reduction of the .225 inch (5.72 mm) minimum length to .025 inch
(0.63 mm) is allowed. Additionally there shall be a smooth ramp transition on the terminus
between the terminus barrel and the crimp sleeve/heat shrink so as not to restrict the function of
the insertion and removal tool during the removal operation.
22. Terminus compression spring shall withstand an applied force of 8 pounds minimum with no
damage.
