7、n for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has

8、 the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Inter

9、national Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicat

10、ion as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent righ

11、ts. ISO 17775 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 10, Aerospace fluid systems and components. ISO 17775 revises ISO/R 47:1957 and ISO 450:1976, cancelled in 1983 and 1998, respectively: ISO/R 47:1957, Aircraft toilet flushing and drawing connec

12、tions ISO 450:1976, Aircraft Connection for water of drinkable quality ISO 17775:2006(E) iv ISO 2006 All rights reservedIntroduction The ground-service interfaces and the mating ground connectors used on most commercial aircraft, as well as on some military and private aircraft, are generally consid

13、ered interchangeable since the designs used are all based on the same original design. This was originally provided by the Roylyn Company in the 1950s and then later used as the basis for other suppliers without the detail dimensions. As a result, there are minor variations in some current products

14、that may have some adverse affects on their performance when mated with parts made by others. This International Standard provides the necessary detail dimensions to ensure that all interface dimensions will be compatible, especially as new suppliers enter the market around the world. INTERNATIONAL

15、STANDARD ISO 17775:2006(E) ISO 2006 All rights reserved 1 Aircraft Ground-service connections Potable water, toilet-flush water and toilet drain 1 Scope This International Standard specifies the detail dimensions of the male connector interfaces, fitted to an aircraft, used for servicing of the pota

16、ble water systems, the toilet-flush water systems, and the toilet drain systems currently in common use. This International Standard is applicable to all commercial aircraft with water and toilet systems and is recommended for military and private aircraft that use water and toilet systems. This Int

17、ernational Standard does not include requirements for the ground half (female) couplings or protective caps, but provides sufficient interface details for such items to be designed. It does not include any specified dimensions for the clearance required around the connector on the aircraft body itse

18、lf for either any protective caps or ground half couplings, although general recommendations are made. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the l

19、atest edition of the referenced document (including any amendments) applies.

20、ut ISO 1302, Geometrical Product Specifications (GPS) Indication of surface texture in technical product documentation 3 Dimensions Dimensions of male fittings shall be as defined in Figure 1 and Table 1. All detail dimensions and tolerances are included to ensure commonality between all aircraft us

21、ing this International Standard. Ground-service connections shall be designed to mate with this common interface. NOTE Space needs to be provided to accommodate the ground-service connector. Space required for the nipple-cap configuration will normally be greater than that required for the ground fi

22、tting. Space needs to be available for the cap assembly to provide space for the ground fitting. ISO 17775:2006(E) 2 ISO 2006 All rights reserved4 Material 4.1 Specific materials are not defined in this International Standard, but all units shall be compatible with the water and chemicals used in th

23、e water and toilet systems of the aircraft. This shall be based on a corrosion-resistant steel material, which shall also provide the required strength and hardness for the intended application. Tests shall be carried out to ensure compatibility of the materials used for the connector with the types

24、 of fluid used on the aircraft. 4.2 Surface and dimensional requirements specified in Figure 1 and Table 1 shall conform to ISO 129-1, ISO 1101 and ISO 1302. 4.3 All corners and fillets shall have a radius of 1,5 mm (0,059 in), unless otherwise specified.
