system in accordance with the data and ordering documents included in the contract or order
(see 6.2.2).
4.1.2 When specified (see 6.2.1) , the pump shall be free of all mercury contamination,
During the manufacturing process, tests, and examination, the product to be offered for
acceptance shall not come in direct contact with mercury or any of its components nor with
any mercury containing device employing a single boundary of containment. The manufacturer
shall certify that the product, when shipped, is free from mercury contamination.
4.2 Quality conformance

4.2.1 Samp ling for performance tests.
4,2.1.1 For a packaged tank and pump unit, a representative number of sets in accord-
ance with table III shall be tested to demonstrate the ability of the unit to function

4.3 Tests.
4.3.1 Performance.
4.3.1.1 Driving units shall be tested as required by the applicable equipment specifi-
cations.
4.3.1.2 One complete pump of each size on order, including the motor and controller,
shall be given a test to determine the overall power consumption of the unit under the
specified conditions. The Naval Ship Engineering Center (NAVSEC) may consider waiver of
overall power consumption tests on pumps if identical units have been previously tested
satisfactorily.
4.3.1.2.1 Performance tests shall ordinarily be conducted at the same time as, and
shall include the inclined operation tests as specified for the driving unit. For inclined
operation tests the unit shall be run at maximum operating speed, but need not be fully
loaded.
4.3.1.3 Performance tests shall demonstrate the ability of the pump to handle its rated
capacity of specified liquid at the maximum temperature and minimum suction head or maximum
suction-lift or vacuum as applicable.
