MIL-DTL-62186C
k. If trial installation on an engine-transmission assembly conforming to Drawing
11655426 is required (see 4.3.7.2).
l. Packaging requirements (see 5.1).
6.3 First article. When requiring a first article inspection, contracting documents should
provide specific guidance to offerors. This guidance should cover whether the first article is a
first article sample, a pre production item, a first production item, and the number of test items.
These documents should also include specific instructions regarding arrangements for
examinations, approval of first article test results, and disposition of first articles. Pre-
solicitation documents should provide Government waiver rights for samples for first article
inspection to bidders offering a previously acquired or tested product. Bidders offering such
products who wish to rely on such production testing must furnish evidence with the bid that
prior Government approval is appropriate for the pending contract.
6.4 Conformance inspection. Affordable conformance inspection with confidence varies
depending upon a number of procurement risk factors. Some of these factors include:
Contractor past performance, government schedules and budget, product material and design
maturity, manufacturing capital equipment and processes applied, the controlled uniformity of
those processes, labor skill and training, and the uniformity of measuring processes and
techniques. During the solicitation, contracting documents should indicate those tests desired
from table III and their designated frequency based on a risk assessment for the procurement.
6.5 Reference information. Historically, MIL-HDBK-454, "General Guidelines for
Electrical Equipment," has provided guidance in procuring the alternator. (Copies of the
specified handbook are available from the Standardization Document Order Desk, 700 Robbins
Avenue, Building 4D, Philadelphia, PA 19111-5094.)
6.6 Definitions.
6.6.1 Fully charged battery. A fully charged battery is defined as a battery having
current consumption of not greater than 4 A and 28 V at room temperature (90 10F) (32
5.8C).
6.6.2 Load current. Load current is defined as that current from generator to batteries
and resistive load, and controlled by the regulator.
6.6.3 Drop. A drop is defined as a volume of fluid equal to 0.03 in3 (0.5 cm3).
6.6.4 Temperature stabilized. A temperature stabilized alternator is defined as a situation
when constant conditions of speed and load current fail to cause a change in alternator oil inlet
and outlet differential temperature by more than 2F (1C) during a 10 minute period.
