MIL-DTL-3992F
6.1.1 Military unique rationale. The hose and hose assemblies are military unique because they are
to be used for applications operating in a temperature range not exceeding +200°F (93.33°C) and not
below -60°F (-51.11°C). Commercial components are not designed to withstand these extreme
conditions or sudden environmental changes and would experience catastrophic failure.
6.1.2 Vacuum hose. Type II hose is intended for, but not limited to, two different specific uses as
follows:
Style A
-
Heavy-duty hose for service on truck-trailer combinations and similar
applications.
Style B
-
Light-duty hose for service in conjunction with the power braking system
on passenger cars and light trucks, where hose is used in a protected
location.
6.2 Acquisition requirements.
6.2.1 Qualified type I hose and hose assemblies. Acquisition documents should specify the following:
a. Title, number, and date of the specification.
b. PIN (see 1.2).
c. Packaging requirements (see section 5).
6.2.2 First article inspection for type II hose and hose assemblies. Acquisition documents should
specify the following:
a. Title, number, and date of this specification.
b. PIN (see 1.2).
c. Quantity required.
d. Whether first article inspection is waived (see 6.4).
e. Lot records if required (see 4.4.1).
f. Name and address of the first article inspection test facility to which first article samples (if
required) are to be forwarded and the name and address of the Government activity
responsible for conducting the first article inspection program (see 6.4).
g. Packaging requirements (see section 5).
6.3 Qualification. With respect to products requiring qualification, awards will be made only for
products which are, at the time of award of contact, qualified for inclusion in Qualified Products List QPL
No. 3992 whether or not such products have actually been so listed by that date. The attention of
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, P.O. Box
3990, ATTN: DSCC-VQ, Columbus, Ohio 43218-3990 or emailed to vqp.chief@dla.mil.
