6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not
mandatory.)
6.1 Intended use. The aluminum fittings are primarily intended for use with threaded aluminum piping
in water or liquid petroleum product service. These fittings are military unique because they must
withstand a hydrostatic proof pressure of 250 psi (1.72 MPa), commercial fittings are not designed to
withstand this pressure.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. PIN (see 1.2)
d. Lot records if required (see 4.2.3).
e. Name and address of the first article inspection test facility to which first article samples, if
required, are to be forwarded (see 4.2.3) and the name and address of the Government
activity responsible for conducting the first article inspection program (see 6.3).
f. Finish, if required see 3.6.
h Packaging (see 5.1).
6.3 First article. The contracting officer should include specific instructions in acquisition documents
regarding arrangements for examinations, approval of first article test results, and disposition of first
article samples. Invitations for bids should provide that the Government reserves the right to waive the
requirement for samples for first article inspection to those bidders offering a product which has been
previously acquired or tested by the Government, and that bidders offering such products, who wish to
rely on such production or test, must furnish evidence with the bid that prior Government approval is
presently appropriate for the pending contract.
6.3.1 Defense Logistics Agency (DLA) waiver of first article test. A waiver of a first article testing will
only be considered by DLA when the contractor has delivered the same item within the last three years,
has no unfavorable quality history, has not changed processes, or changed any subcontractors. DLA will
not accept first article testing results outside the stated requirements.
6.4 Environmentally preferable material. Environmentally preferable materials should be used to the
maximum extent possible to meet the requirements of this specification. As of the dating of this
document, the U.S. Environmental Protection Agency (EPA) is focusing efforts on reducing 31 priority
chemicals. The list of chemicals is available on their website at
https://www.epa.gov/epawaste/hazard/wastemin/index.htm. Included in the EPA list of 31 priority
chemicals are cadmium, lead, and mercury. Use of the materials on the list should be minimized or
eliminated unless needed to meet the requirements specified herein (see section 3).
6.5 PIN. The PIN to be used for pipe fittings acquired to this specification is to be in accordance with
the applicable specification sheets (MIL-DTL-52618/1 through MIL-DTL-52618/9).
