18、text of this standard and the references ci-ted herein, the text of this standard shall take precedence. b 3. DEFINITIONS 3.1 Shipboard dry air support system. A shipboard dry ait: support: system is a system specifically designed to provide high quality dry air with standard characteristics as spec

19、iEied herein. Each system is composed of the necessary dehydrators, filters, dew point indicators, coritrol panels, temperature, flow and pressure indicators, piping, valves, and al.1 other accessories required to ensure a continuous supply OE dry, oil-free air to user equipment. Shipboard dry air s

20、upport systems are usually pressurized by t?ie ship service low pressure air compressors (see MIL-STD-1399, section 100). O 4. REQUIREMENTS 4.1 The interface requirements and constraints established herein are inandatory (see requirements of MIL-STD-1399). 5. INTERFACE CHARACTEKICTICS AND CONSTRAINT

21、S 5.1 Interface characteristics. The interface characteristics of the ships dry air support system ace given below. Each shipboard system will provide dry, oil-free air with the characteristics of 5.1.1 through 5.1.5 to the equipment interface. (a) Hydrocarbons - 50 parts per million by weight (b) P

22、articulates - 5 microns 5.1.2 Temperature. The temperature will be 150 degrees Fahrenheit (OF) maximum. 5.1.3 Pressure. The pressure from the discharge of the dry air system dehydrators may range from 67 to 1.50 pounds per square inch (Ib/in2) gauge. If lower pressures are required, standard dry air

System capacity will be based on the user equipment requirements as documented in 6.1, with an allowance for standby capacity and future growth. 5

27、.2 Interface constraints. The interface characteristics of the ships dry air support system impose certain constraints on the design and instal.lation of equipment utilizing such support. These constraints are described in 5.2.1 and 5.2.2. 5.2.1 Compatibility. The design and installation of equipmen

28、t utilizing ships dry air support must be compatible with the interface characteristics given in 5.1. 5.2.2 User air requirements. The dry air requirements for each user shall be reported as specified i.n 6.1. 6. DOCUMENTATION REQUIREMENTS 6.1 DD Form 1423. When this standard is invoked, the followi

29、ng data requirements, as applicable, shall be specified by the Principal Development Aciivity (PDA) on Cntract Data Requirements List- (CDRL) DD Form 1423 attached to the contract or order. NAVSEA, Code 56Y31, shall be included in the distri- bution listed in block 14 of DD Form 1423 for data specif

In achieving the purpose of this section it is recognized I that there must be some flexibility of application. During the early design stage o equipment uti

35、lizing the ships dry air support system it may become apparent that significant advantages in the overall design and operation of such equipnent can be achieved by deviating from the standard characteristics speci- Eied lierein. In such instance, the provisions of the deviations requirements o MIL-S

36、TD-1399 must be complied with. 7.2 Deviation procedure. When invoking deviations to this section, reports shall be made in accordance with 8.1. 8.
