MIL-STD-2193 Ship Hydraulic System ComponentsThis standard provides design, construction, and testing requirements that are common to most components used in ship hydraulic power transmission and control systems. This standard does not establish configuration requirements, pressure, flow, or performance requirements for any specific component.

MIL-STD-2193C(SH)

5.3.11 Shock. The components shall perform as specified herein and in the applicable component specification after being subjected to the high-impact shock test, Grade A, Class I as specified in MIL-S-901. The components shall be cycled after each blow during the test to determine that no damage has occurred as a result of the impact. A momentary interruption of the component function during shock testing shall not be interpreted as a failure. Post shock test inspection shall include all functional and operational tests to demonstrate that the specified requirements are met.

5.3.12 Contamination sensitivity. When required by the component specification, the components shall meet the requirements of the applicable component specification when subjected to a contamination sensitivity test procedure approved by the Naval Sea System Command (NAVSEA) (see 6.1.2.d). The test circuit shall be modified by the addition of a component test loop as shown on figure 1.

5.3.13 Component cleanliness. Component cleanliness levels shall be as identified in the procurement specification. Where the procurement specification invokes this military standard but does not identify a specific cleanliness level, the fluid sampled from the component shall not exceed the particle counts identified in table VII.

TABLE VII. Component cleanliness.

Particle size	Particles per 100 mL
Greater than 15 micrometers	14,000
Greater than 25 micrometers	2,500
Greater than 50 micrometers	400
NOTE: Unless otherwise specified (see 6.2), the above counts apply to samples taken in accordance with practice A of ASTM F303.

5.4 Drawing practices. Engineering drawing practices for hydraulic component drawings shall be in accordance with ASME Y14.100.
