ISO 5356-1:2015规定了用于连接麻醉和呼吸设备（如呼吸系统、麻醉气体清除系统和汽化器）的锥和套筒的尺寸和计量要求。因此，锥体和套筒本身不被视为设备。 它给出了以下锥体和套筒的要求:用于新生儿和儿科呼吸系统的8.5mm和11.5mm尺寸；呼吸系统中一般使用的15 mm和22 mm尺寸；22 mm锁紧插座（包括性能要求）；尺寸为23 mm，用于蒸发器，但不用于呼吸系统； 尺寸为30 mm，用于将呼吸系统连接至麻醉气体清除系统。 它没有具体说明医疗设备和附件上提供这些锥和插座。 锥体和套筒的应用要求不包括在内，但在特定医疗器械和附件的相关国际标准中已经或将要给出。ISO 5356 2规定了螺纹承重连接器的要求。

ISO 5356-1:2015 specifies dimensional and gauging requirements for cones and sockets intended for connecting anaesthetic and respiratory equipment, e.g. in breathing systems, anaesthetic gas scavenging systems, and vaporizers. The cones and sockets are therefore not regarded as devices in their own right. It gives requirements for the following cones and sockets: 8,5 mm and 11,5 mm sizes intended for use in neonatal and paediatric breathing systems; 15 mm and 22 mm sizes intended for general use in breathing systems; 22 mm latching sockets (including performance requirements); 23 mm size intended for use with vaporizers, but not for use in breathing systems; 30 mm size intended for the connection of a breathing system to an anaesthetic gas scavenging system. It does not specify the medical devices and accessories on which these cones and sockets are to be provided. Requirements for the application of cones and sockets are not included, but are or will be given in the relevant International Standards for specific medical devices and accessories. Requirements for screw-threaded weight-bearing connectors are specified in ISO 5356 2.
