3.15 Test zones. The projectiles, regardless of conditioning
temperature, shall be fired either at zone seven (7) or zone three
(3) as required per test sequence.
3.16 Compressive strength of molding compo und. The molding
compound for the Housing, Timing and Fuzing (Dwg. 9298450) shall
comply with MIL-M-48245 and shall exhibit a compressive strength of
29,000 to 38,000 psi.
3.17 Qualification testing of Electrical components.. The
components of th e electronics assemb ly P/N 9298495 that require
qualification by electrical and mechanical testing are as follows:
9298496
Resistor Network
9298507/MIL-I-48331
Integrated Circuit
(CMOS)
9298503
Capacitor, Dual
9298509
Capacitor C3
9298658
Capacitor Cl and C2
9298555
Transistors, NPN, Q1,

Components that were qualified in previous contracts for the
Housing, Timing and Fuzing do not require requalification except as
specified in paragraph 3.17.4.
3.17.1 Qualification of components. Qualification of the
components listed abo ve shall be accomplished by the following:
(1) Electrical and mechanical laboratory tests. - The
components shall meet the requirements of the applicable
component drawings and specifications and shall be conducted
at the contractor's facility. Unless otherwise specified on
the applicable component drawing/specification, sampling plans
for non-destructive tests shall be 77-1-2 and for destructive
tests shall be 20-0-1.
(2) Yuma Proving Ground Ballistic Testing. - The above
components must survive a 155MM gun environment (zone 7,
M119A2 charge), on a comparative basis with previously
qualified components.
