This standard provides design, construction, and testing requirements that are common to most components used in ship hydraulic (power trans
20、mission and control) systems. This standard does not establish configuration requirements, pressure, flow, or performance requirements for any specific component. 1.2 Purpose. The purpose of this standard is to standardize the design, construction, and testing requirements for hydraulic components u
21、sed in shipboard hydraulic systems, such as valves and actuators. This standard provides the design, construction, and testing requirements for military specifications for ship hydraulic components and the design, construction, and testing requirements in specifications developed by shipbuilders and
22、 contractors for the acquisition of ship hydraulic components. 1.3 Implementation guidance. Where suitable for use, the selection of components should be made in the following order: a. As required by the applicable detail shipbuilding specification or other invoked contractual requirements. b. As i
23、dentified in the hydraulic system sections of MIL-STD-438 and MIL-STD-777, as applicable. c. In accordance with military and industry specifications and standards with configuration control which meet the requirements of this standard. Where no other guidance is available, SAE-J1783 may be used for
24、selecting hydraulic directional control valves. d. Configurations in accordance with military and industry specifications. (Minor modification such as seal substitution to meet this standard is acceptable.) e. Previously used components, modified if necessary, to comply with this standard. f. Commer
25、cial components, modified as necessary, to comply with this standard. g. New components designed in accordance with this standard. 2. APPLICABLE DOCUMENTS 2.1 General. The documents listed in this section are specified in sections 3, 4, or 5 of this standard. This section does not include documents
26、cited in other sections of this standard or recommended for additional information or as examples. While every effort has been made to ensure the completeness of this list, document users are cautioned that they must meet all specified requirements of documents cited in sections 3, 4, or 5 of this s
27、tandard, whether or not they are listed. 2.2 Government documents. 2.2.1 Specifications, standards, and handbooks.
