ISO 17775:2006规定了安装在飞机上的公接头接口的详细尺寸，用于维修目前常用的饮用水系统、厕所冲洗水系统和厕所排水系统。ISO 17775:2006适用于所有配备水和厕所系统的商用飞机，建议用于使用水和厕所系统的军用和私人飞机。 ISO 17775:2006不包括对半接地（内螺纹）联轴器或保护盖的要求，但提供了设计此类项目的足够接口细节。虽然提出了一般性建议，但它不包括任何防护帽或地半联轴器在机身连接器周围所需间隙的任何规定尺寸。

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.
