4.4.1 Qualification test sample. In testing for qualification, a test sample consisting of a single
length of conduit with ends treated as in 3.6.8 shall be submitted for each size and type that is to be
qualified. The length of the test sample shall be 4 feet for conduit less than 2 inches in diameter, 6
feet for 2-inch and 2-1/2 diameter, and 8 feet for 3-inch diameter conduit.
4.4.2 Failures. One or more failures shall be cause for refusal to grant qualification approval.
4.4.3 Qualification of similar conduit. Qualification of a manufacturer's Type 2 conduit will
automatically constitute qualification of that manufacturer's Type 1 conduit of the same size provided
that the construction, manufacturing process, and materials (excluding the rubber jacket) are identical
in both cases.
4.4.4 Retention of qualification. The Naval Sea Systems Command will request a certification
report at 2-year intervals from each manufacturer whose conduit is listed on the QPL. To retain
qualification, the manufacturer shall submit the certification signed by a responsible official of
management attesting that the conduit listed on qualified parts list is still available from the listed plant;
can be produced under the same conditions as originally qualified, i.e., same process, materials,
construction, design, manufacturer's part number, or designation; and meets the requirements of the
current specification. Failure to provide certification will be cause for removal from the QPL. After
completion of certification review, the QPL will be reprinted to show the date of validation. (DD
Form1718, Certification of Qualified Products, shall be used for obtaining certification.)
4.5 Quality conformance inspection. The supplier shall perform a quality conformance inspection
at the time of production on each production lot (see 4.5.1) manufactured under this specification to
prove compliance with applicable requirements. The quality conformance inspections shall be as
specified in table IV, in the order shown.
4.5.1 Production lot. Conduit of one size and type, and manufactured from the same materials
under essentially the same conditions during an identifiable production period, shall be considered a
production lot. The manufacturer shall assign a lot number, for identification purposes, to each
production lot.
4.6 Methods of inspection. Visual and dimensional inspections shall be made on each length of
bare tubing and on the completed conduit in accordance with 4.6.1, 4.6.2, 4.6.3, and 4.6.4. Any
defects or failure to meet the requirements specified in 3.6, 3.9, and 3.11 shall be corrected or shall
be cause for rejection.
