a. The battery's normal attachment points (such as brackets, flanges, or hold-down bars)
shall retain the entire battery intact in the test fixture during and after the test.
b. Mechanical bending and distortion are acceptable.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified
as follows:
a. Qualification inspection (see 4.2).
b. Conformance inspection (see 4.3).
4.2 Qualification inspection. Qualification inspection shall consist of the examinations and
tests specified in the applicable specification sheet and S9310-AQ-SAF-010 safety testing (see
6.4, 6.5, 6.17.1, and 6.17.2). The specification sheets also list the order in which the tests shall
be conducted. The samples shall be representative of the items intended to be supplied under
this specification. The samples shall not be produced with the use of any equipment or
procedure not normally used in production of the battery. Eighteen complete batteries and one
dry unassembled battery with all parts shall be furnished for inspection, if new cell technology.
If existing cell technology is utilized, then 10 complete batteries and one dry unassembled
battery with all parts shall be furnished for inspection. If the battery has an integral charger, then
all qualification samples shall contain the integral charger; in addition, one charger shall be
supplied separately from the battery. If receptacles that are dimensionally equivalent to
MIL-PRF-18148/3 receptacles are used, then five wormgear retaining pins shall be furnished for
inspection. If the outer battery container is nonmetallic, two such containers and a piece of the
container material at least 15.24 centimeters (6 inches) by 7.62 centimeters (3 inches) (nominal)
shall be supplied as test samples for qualification testing. All samples shall be marked with
identifying information in accordance with 3.7 (see 6.2.d).
4.3 Conformance inspection. Conformance inspection shall consist of the tests specified in
the applicable specification sheet (see 6.6, 6.7, and 6.8). Batteries produced under this
specification shall be identical in every respect to the qualification sample tested and found
satisfactory, except for changes previously approved by the Government. Any unapproved
changes from the qualification sample shall constitute cause for rejection.
4.3.1 Inspection of product. Every battery shall be subjected to and pass group A tests; each
shall also have been part of the same inspection lots from which group B samples were selected
and which passed group B testing. Batteries produced under this specification shall successfully
complete groups A and B inspection (see 4.3.4 and 4.3.5).
