As a result, there are minor with parts made by others. This International Standard provides the necessary detail dimensions to ensure world. iv BS ISO 17775:2006 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 potable water systems, the toilet-flush water systems, and the toilet drain 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 details for such items to be designed. It does not include any specified Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
