MIL-PRF-22097J
6.2 Acquisition requirements. Acquisition documents must specify the following:
a.
Title, number, and date of this date of this specification, the applicable associated specification, and the
complete PIN.
If not otherwise specified (see 2.1), the versions of the individual documents referenced will be those in
b.
effect on the date of release of the solicitation.
Packaging requirements (see 5.1).
c.
Allowable substitution (see 3.29).
d.
6.3 Qualification. With respect to products requiring qualification, awards will be made only for products which are,
at the time of award of contract, qualified for inclusion in the Qualified Products List whether or not such products
have actually been so listed by that date. The attention of the contractors is called to these requirements, and
manufacturers are urged to arrange to have the products that they propose to offer to the Federal Government tested
for qualification in order that they may be eligible to be awarded contracts or orders for the products covered by this
specification. Information pertaining to qualification of products may be obtained from Defense Supply Center,
Columbus, ATTN: DSCC-VQP, 3990 East Broad Street, Columbus, Ohio 43218-3990.
6.4 Sequence for inspection, measurements, and tests. The sequence for inspections, measurements, and tests
should be in accordance with table XII.
6.5 High resistance and voltages. Where voltages higher than 250 V rms are present between the resistor circuit
and grounded surfaces on which the resistor is mounted, or where the dc resistance is so high that the insulation
resistance to ground is an important factor, secondary insulation to withstand the conditions should be provided
between the resistor and mounting or between the mounting and ground.
6.6 Mounting resistors. Resistors should not be mounted by their lugs or flexible wire leads. Mounting hardware
should be used. Printed circuits types are frequently terminal mounted, although brackets may be necessary for a
high shock and vibration environment.
6.7 Resistance temperature characteristic. Consideration should be given to temperature rise and ambient
temperature of resistors under operation, in order to allow for the change in resistance due to resistance temperature
characteristic. Resistance tolerance may be easily be exceeded unless care is exercised.
