4.3 First article inspection. First article inspection shall be performed
at a laboratory satisfactory to NAVSEA on each class. Either horizontal or
vertical units may be submitted. The several first article tests on one pump
design may be conducted concurrently, if practicable. The test shall fully
establish that the product has the reliability and performance capability
specified herein. A first article test report shall be prepared in accordance
with the data ordering document included in the contract or order (see 6.2.2).
The following tests shall be performed:
(a) Performance evaluation tests specified in 4.6.6 through 4.6.6.3
and the examination specified in 4.5. Performance evaluation
tests shall be conducted on one pump of each type, design and
size on each contract or order (see 4.6.6).
(b) Design evaluation tests as specified in 4.6.7 through 4.6.7.6.
Design evaluation tests shall be conducted on one pump of each
type, design and size (see 4.6.7).
4.3.1 First article inspection shall include all sizes of each type and
both horizontal and vertical units.
4.3.2 The contractor of a specific class pump shall submit design data
and calculations, as specified in 3.8 to the design review agency for review
and approval as a prerequisite to the performance of the first article tests
specified herein. The design record, as specified in 3.9, shall be submitted
upon completion of the first article tests.
4.4 Quality conformance inspection. Each pump (and subcomponents of each
pump, if applicable) shall be examined as specified in 4.5 and tested as speci-
fied in 4.6.1 through 4.6.5. Quality conformance inspection shall be fully
documented by a prescribed test procedure and a written record of the perfor-
mance and findings of each test (see 6.2.2). A compilation of the documentation
of all the quality conformance tests performed on each pump shall be furnished
in duplicate (see 6.2.2).
4.5 Examination. Pumps shall be examined in accordance with a completed
parts examination check list accompanying each part or assembly. The examination
shall be performed by inspection personnel not engaged in the fabrication and
assembly of the part. The check list for each part shall include accurate part
identification and shall list the specific attributes which determine the part's
acceptability.
The check list shall be filled in during the time of examination.
The check list shall be arranged in tabular form, calling forth separately the
following examination assignments, each accompanied by the specific attributes
of acceptability which shall be checked or measured, and the findings recorded:
(a) Dimensions. They shall be as indicated on the approved design
drawing. Rotating parts shall be examined for balance and
maximum permissible run-out as indicated on the drawings.
(b) Materials. Visual examination for compliance with approved
design drawings. Any appearance of nonconformance shall be
further verified by appropriate tests.
(c) Cleanliness. Examination for cleanliness shall apply equally
to parts examination prior to assembly as well as subassemblies
and the completed product.
