15、n) 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 rep
16、resented 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 a
17、re 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 Internatio
18、nal 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.

20、technical cooperation between ISO and CEN (Vienna Agreement). This second edition cancels and replaces the first edition (ISO 7396-2:2000), which has been technically revised.

The anaesthetic gas scavenging system comprises three main parts: a tran
23、sfer system, a receiving system, and a disposal system. A schematic diagram of typical anaesthetic gas scavenging systems is shown in Figure 1. Requirements for receiving systems and transfer systems are specified in ISO 8835-3. Type-specific connections for terminal units are specified in ISO 9170-
24、2. In this part of ISO 7396, specifications and test procedures are given to ensure compatibility between the components of the system. This part of ISO 7396 specifies requirements for pipelines for anaesthetic gas scavenging systems for anaesthetic gases and vapours. It is intended for use by those
