4.5.20 Microcircuit mounting. The microcircuit device
shall be mounted and soldered per MIL-S-45743 or MIL-S-46844 as
applicable to the ADAM electronic board assembly.
4.5.21 ADAM wedge assembly. The electronic board assembly
will be molded into a complete functionable ADAM wedge, using
molding compound MC8196-01.
4.5.22 Pre-shock electrical tests. After molding, the
microcircuit shall be electrically tested using the criteria
set forth in MIL-P-48189.
4.5.23 Projectile loading. The test wedge assemblies
shall be loaded into a 155MM Test Vehicle Projectile as defined
by drawing 28010049 or 28010099. Modifications to the
projectile base plate, ogive and to components internal to the
ogive are allowed as long as those modifications maintain the
same load conditions and packaging constraints on the wedge
cargo.
4.5.24 Howitzer firing. The projectile shall be fired in
a 155MM Howitzer utilizing an M109 or an M126 tube with a zone
7X equivalent firing. A zone 7X equivalent firing is defined
as a firing wherein the breach pressure is 122% of the
Recommend Mean Pressure (RMP) for a zone 7 firing, per Report
No. AD826675L or APG Report No. 1375. A zone 7X propellant
charge can be obtained by heating a zone 7 propellant charge to
145F or by adding extra propellant as required by ambient
temperature conditions.
4.5.26 Flight ejection. When soft catch techniques are
not used, the projectile fuze setting must be such that a cargo
ejection height greater than 2000 feet is obtained. Ejection
at lower altitudes may be considered grounds for no test.
4.5.27 Static election (Optional). Ejection and impact
shock environments may be simulated on soft catch units. The
simulated ejection will consist of firing the projectile
expulsion charge, AR drawing 9216855, with the projectile
mounted rigidly nose down is such a manner that the cargo is
ejected into the air and allowed to fall back to the ground in
a random orientation.
