Aircraft -- Ground-service connections -- Potable water, toilet-flush water and toilet drain
ISO 17775:2006 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. ISO 17775:2006 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. ISO 17775:2006 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 itself for either any protective caps or ground half couplings, although general recommendations are made.

ISO (the International Organization 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 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.
International 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. Publication 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 rights.
ISO 17775 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, SubcommitteeSC 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 connections
⎯ ISO 450:1976, Aircraft — Connection for water of drinkable quality

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. 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 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 theworld.
