MIL-DTL-0045585E (AR)
inspection equipment conforming to Drawing 11017981, 11018356, and 11691396.
Links shall be assembled to the test, mandrel with the leaf spring areas of the link seated
in the groove of the test-mandrel. The test mandrel, with assembled link, shall be
inserted into the test fixture and the load shall be applied to the link in the direction to
strip the link from the test mandrel (see Drawing 11691396). The maximum load
required to strip the link from the test mandrel, excluding the initial force (breakaway) to
move the link, shall be recorded as the stripping force. Observation shall be made for the
requirement of the applicable drawing. This test is a non-destructive test. Parts shall be
used for subsequent tests.
4.5.13 Uncoupling force test. Each link of the sample shall be tested using
inspection equipment conforming to Drawing 11017980, 11018357, and 11691396. The
links shall be inserted into the test fixture and the load shall be applied in the direction
specified on Drawing 11691396 until the links are uncoupled. The maximum load
required to uncouple the link shall be measured as the uncoupling force. The test shall be
conducted so that each coupling and each loop in the sample is tested. Observation shall
be made for the requirement of the applicable drawing. This test is a destructive test.
Parts so tested shall not be returned to the lot.
4.5.14 Determination of cleanliness test. Links shall be tested for cleanliness
requirements in accordance with MIL-STD-2073-1. This test is a non-destructive test.
Parts so tested may be returned to the lot.
4.5.15 Functioning test. Links shall be tested by assembling the links into belts
using Government standard 40mm, M385 practice ammunition. The belts shall be fired
in intermittent bursts of 5 to 15 rounds from the MK19, MOD III, Grenade Machine Gun
mounted in a Government approved mount with standard chuting.
4.5.16 Pivot lug diameter inspection. The pivot lug diameter, max., shall be
inspected on each side of the coupling in two (2) places approximately 90 degrees apart
for a total of four (4) measurements. Standard measuring and test equipment, a go ring (1
measurement per side), or a contractor designed gage shall be used. The pivot lug
diameter, max., shall be inspected on each side of the coupling in two (2) places
approximately 90 degrees apart for a total of four (4) measurements. Standard measuring
and test equipment or a contractor designed gage shall be used. All gaging shall be
approved by the Government.
4.5.17 Inspection Equipment. The inspection equipment required to perform the
examination and tests prescribed herein is described in the Inspection Method Column in
the tables starting with paragraph 4.4.2.1. Inspection equipment used for acceptance of
product shall be capable of repeatable measurements, by various experienced
inspection/test personnel, to an accuracy of 10% or better of the total tolerance of the
characteristic being inspected. Any automated acceptance inspection equipment (AAIE)
prove-out shall be performed in accordance with MIL-A-70625 (see 6.6).
4.5.18 Workmanship. Visually verify that all parts and assemblies meet
requirements of paragraph 3.4.
