(f) Alignment. The equipment and its subassemblies shall be examined
to ensure that the alignment is as specified.
(g) Adjustment. The adjustment of safety, control, and monitoring
devices shall be verified and the settings recorded. Settings
which should not be tampered with, once adjusted, shall be tagged
with an appropriate precautionary warning.
(h) Preservation. The presentation used, the method of application,
and recommended procedure for removal of preservative prior to
placing the unit in service shall be stated on a supplemental
sheet and attached to the check list.
4.6 Tests. The contracting activity and Government representatives shall
have the right to examine the facilities at the contractor's plant and at the
contractor's subcontractor's plants, and to witness all tests specified herein.
Failures, deficiencies, and discrepancies revealed during the performance of the
specified tests and the corrective measures taken, shall be recorded and fully
documented. After correction of deficiencies, tests shall be repeated to the
extent necessary to ascertain acceptability for the modified pump. Major
failures indicative of the design deficiency (as distinguished from shop error or
faulty workmanship) shall be reported to the design review agency before a
correction is made. Except where specifically required herein to be tested with
the actual device, tests of turbine driven pumps may be conducted using a
substitute driver provided the actual device separately passes the tests required
by its specification.
4.6.1 Shop tests. Shop tests shall be performed on each pump being
supplied (and subcomponents of each pump if applicable). Each shop test shall be
fully documented by a prescribed test procedure and a written record of the
performance and findings of each test. The following shop tests shall be
performed on each pump:
(a)
Hydrostatic pressure test (see 4.6.1.1).
(b)
Over-speed test (see 4.6.1.2).
(c)
Mechanical soundness and capacity test (see 4.6.1.3).
(d)
Noise test (to be performed only when specified (see 6.2 and
4.6.1.4)).
4.6.1.1 Hydrostatic pressure test.
Each pump casing shall be tested hydro-
statically to a pressure one and one-half times the maximum discharge pressure or
total head, whichever is greater but in no case less than 50
The
hydrostatic test pressure shall be maintained for at least 30 minutes or longer
as necessary for examination of entire casing.
4.6.1.1.1 Acceptance criteria.
The pump shall exhibit no leakage through
the pressure boundary,
4.6.1.2 Over-speed test. Each pump driven by a variable speed driver that
can overspeed shall be operated continuously for 30 minutes at a speed 25 percent
above maximum design operating speed. The pump need not be under load except as
necessary to prevent damage or injury. Continuous shaft and rigid coupled pumps
shall be tested with the driver. Units separately driven through flexible
