6、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 the right to be represented on that committee. International

7、 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. International Standards are drafted in accordance with the rules g

8、iven 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. Publication as an International Standard requires approval by at leas

9、t 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 rights. ISO 17775 was prepared by Technical Committee ISO/TC 20,

11、e quality BS ISO 17775:2006iv Introduction 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 considered interchangeable since the designs used are all based on the same original design. Thi

12、s 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 that may have some adverse affects on their performance when mated with parts made by othe

13、rs. 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. BS ISO 17775:20061Aircraft Ground-service connections Potable water, toilet-flush water and toilet drain

14、 1 Scope This International Standard specifies the detail dimensions of the male connector interfaces, fitted to an aircraft, used for servicing of the potable water systems, the toilet-flush water systems, and the toilet drain systems currently in common use. This International Standard is applicab

15、le to all commercial aircraft with water and toilet systems and is recommended for military and private aircraft that use water and toilet systems. This International Standard does not include requirements for the ground half (female) couplings or protective caps, but provides sufficient interface d

16、etails for such items to be designed. It does not include any specified dimensions for the clearance required around the connector on the aircraft body itself for either any protective caps or ground half couplings, although general recommendations are made. 2 Normative references The following refe

17、renced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 129-1, Technical drawings Indication of dimensions and toleranc

18、es Part 1: General principles ISO 1101, Geometrical Product Specifications (GPS) Geometrical tolerancing Tolerances of form, orientation, location and run-out ISO 1302, Geometrical Product Specifications (GPS) Indication of surface texture in technical product documentation 3 Dimensions Dimensions o

19、f 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 using this International Standard. Ground-service connections shall be designed to mate with this common interface. NOTE Space needs to be provide

20、d to accommodate the ground-service connector. Space required for the nipple-cap configuration will normally be greater than that required for the ground fitting. Space needs to be available for the cap assembly to provide space for the ground fitting. BS ISO 17775:20062 4 Material 4.1 Specific mate

21、rials are not defined in this International Standard, but all units shall be compatible with the water and chemicals used in the 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

22、intended application. Tests shall be carried out to ensure compatibility of the materials used for the connector with the types 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

23、 and fillets shall have a radius of 1,5 mm (0,059 in), unless otherwise specified.
