MIL-STD-2193 Revision C, November 30, 2012
SHIP HYDRAULIC SYSTEM COMPONENTS
Components to military specifications. When a component is procured to military specification, the tests in this standard apply only to the extent identified in the component military specification.
Commercial components and components to shipbuilder prepared specifications. Every test need not be applied to each component. The procuring activity has the responsibility for determining if any of the tests may be deleted based on the following guidance:
a. For standard commercial components being used within the applicable design parameters (e.g., pressure, temperature, speed, environment, etc.), the tests for adverse tolerance and extreme temperature functioning are not required.
b. Reliability and maintainability requirements need be included in the component specification only when required by the shipbuilding or other higher level specification.
c. High-impact shock requirements need not be applied if the components are used solely in a system not subject to these requirements.
d. The contamination sensitivity test may be limited to those electro-hydraulic servo valves, electric driven motors, and hydraulic pumps not in accordance with a military or industry specification listed in Acquisition Streamlining and Standardization Information System (ASSIST) Online. However, contaminant sensitivity test procedures do not specify fail/pass criteria. Accordingly, the fail/pass criteria may be specified in the procurement specification. (NAVSEA Hydraulics TWH, SEA 05Z4, should be consulted regarding contamination sensitivity test procedures and fail/pass criteria.)
e. For some tests, guidance on the applicability of the test is identified in the test procedure.
