MIL-DTL-24643C
6.3 Special clause. Except when small quantities are to be purchased, invitations for bid and contracts or orders
should specify the following:
"In order to compensate for handling and probable loss in issue, remnant lengths will be subject to the
price reductions specified in table V. In order that the number of lengths be kept to a minimum
consistent with good manufacturing practices, for each type and size of cable on the contract or order,
not less than 70 percent of the total footage to be shipped will be in standard lengths, and not more than
30 percent may be in any combination of random and remnant lengths. When the total quantity of any
one item is six nominal lengths or less, a footage approximately two nominal lengths (in lieu of 30
percent) may be in any combination of random and remnant lengths. When the total quantity of any one
item is two nominal lengths or less, the total footage may be in any combination of random lengths."
6.4 Time delay. Comparison inspection will normally require 40 calendar days from the date the sample is sent to
the government designated laboratory to the date the inspection results are received by the manufacturer. This time
delay should be taken into consideration by a contractor when estimating delivery time.
6.5 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 Qualified Products List QPL No. 24643
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
Commander, Naval Sea Systems Command, ATTN: SEA 05B5, 1333 Isaac Hull Avenue, SE, Stop 5160,
Washington Navy Yard DC 20376-5160 or emailed to CommandStandards@navy.mil. An online listing of
products qualified to this specification may be found in the Qualified Products Database (QPD) at
6.5.1 Qualification specimens. A manufacturer seeking qualified products listing (QPL) will manufacture and
be responsible for testing a cable type and size required for group qualification in accordance with table VII. When
a manufacturer desires qualification of an individual type, size, or group, the selection of test specimens and scope
of qualification will be subject to review. For specification sheets (see 3.1) having more than one type of insulation
compound, each insulation type will require qualification. A sufficient length of any test specimen will be
manufactured at one time. Qualification will apply for armored, unarmored, and unarmored with overall shielded
cables.
6.5.1.1 Authorized testing. Authorized testing of qualification samples outlined in table VII or testing of
selected samples to incorporate alternate materials in the originally approved Details of Construction Sheets and
approval of low smoke electrical cables based on satisfactory test results for the representative samples should not in
any way be construed as meaning that only the type/size variation of the representative sample(s) has to meet the
specification requirements. All types/sizes/variations comprising the group(s) represented by the test sample(s)
must meet all specification requirements.
6.5.2 Qualification retention. In order to maintain qualification, each cable manufacturer will annually submit
a certification that materials previously qualified have not changed in composition or supplier since the previous
qualification testing was performed, and will every three years perform the following tests in accordance with the
applicable tests (see table VI) on all materials for which a requirement is specified:
a.
Halogen content
b.
Toxicity index
c.
Acid gas
d.
Smoke index
e.
Immersion
6.6 Sub-contracted material and parts. The preparation for delivery requirements of referenced documents
listed in section 2 do not apply when material and parts are acquired by the contractor for incorporation into the
equipment and lose their separate identity when the equipment is shipped.
