The work of preparing International Standards is normally ca
21、rried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. I
22、SO collaborates closely with the InternationalElectrotechnical 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 Internationa
23、l Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational 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
24、 of this document may be the subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 5364 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,Subcommittee SC 2, Tracheal tubes and other equipment.This fourth editi

30、l Standard is not applicable to metal oropharyngeal airways, nor to requirements concerningflammability of oropharyngeal airways.Flammability of oropharyngeal airways, for example if flammable anaesthetics, electrosurgical units or lasersare used, is a well-recognized hazard. It is addressed by appr
