32、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
33、 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 g
34、iven 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 leas
35、t 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 18779 was prepared by the European Committee for Stan
36、dardization (CEN) Technical Committee CEN/TC 215, Respiratory and anaesthetic equipment, in collaboration with Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 3, Lung ventilators and related equipment, in accordance with the Agreement on technical cooperation b
37、etween ISO and CEN (Vienna Agreement). ENISO18779:2005IS:97781 O5002(E) vi I SO 5002 All irthgs ersedevrIntroduction This International Standard specifies requirements for oxygen and oxygen mixture saving devices (called here conserving devices) that are used to supply respiratory gases during thera
38、py. These devices are for domiciliary use only. Annex AA contains a rationale for some of the requirements. It is included to provide additional insight into the committees reasoning that led to a requirement and to identify the hazards that the requirement addresses. Clauses and subclauses marked w
39、ith an asterisk (*) after their number have a corresponding rationale contained in Annex AA. This International Standard is a Particular Standard based on IEC 60601-1:1988, including Amendments 1 (1991) and 2 (1995), hereafter referred to as the General Standard. The General Standard is the basic st
40、andard for the safety of all medical electrical equipment used by or under the supervision of qualified personnel in the general medical and patient environment; it also contains certain requirements for reliable operation to ensure safety. The General Standard has associated Collateral Standards an
41、d Particular Standards. The Collateral Standards include requirements for specific technologies and/or hazards and apply to all applicable equipment, such as medical electrical systems, EMC, radiation protection in diagnostic X-ray equipment, software, etc. The Particular Standards apply to specific
42、 equipment types, such as medical electron accelerators, high frequency surgical equipment, hospital beds, etc. NOTE Definitions of Collateral Standard and Particular Standard can be found in IEC 60601-1:1988, 1.5 and A.2, respectively. To facilitate the use of this International Standard, the follo
43、wing drafting conventions have been applied. This International Standard uses the same main clause titles and numbering as the General Standard, for ease of cross-referencing of the requirements. The changes to the text of the General Standard, as supplemented by the Collateral Standards, are specif
44、ied by the use of the following words. “Replacement” means that the indicated clause or subclause of the General Standard is replaced completely by the text of this International Standard. “Addition” means that the relevant text of this Particular Standard is a new element (e.g. subclause, list item
45、, note, table, figure) additional to the General Standard. “Amendment” means that an existing element of the General Standard is partially modified by deletion and/or addition as indicated by the text of this Particular Standard. To avoid confusion with any amendments to the General Standard itself,
46、 a particular numbering has been employed for elements added by this International Standard: subclauses, tables and figures are numbered starting from 101; additional list items are lettered aa), bb), etc. and additional annexes are lettered AA, BB, etc. In this International Standard, the following
47、 print types are used: requirements, compliance with which can be verified, and definitions: roman type; notes and examples: smaller roman type; ENISO18779:2005IS:97781 O5002(E) I SO 5002 All irthgs ersedevr vii description of type of document change and test methods: italic type; terms defined in t
