34、er 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 organizations, government

35、al 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 given in the ISO/IEC Direct

36、ives, 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 least 75 % of the member bodie

37、s 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 18777 was prepared by the European Committee for Standardization (CEN) Technica

38、l 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 between ISO and CEN (Vienna

39、 Agreement). BS EN ISO 18777:2009 ISO 18777:2005(E) vi ISO 2005 All rights reservedIntroduction This International Standard specifies requirements for liquid oxygen systems which are used as a source of supply for oxygen therapy. Annex AA contains a rationale for some of the requirements. It is incl

40、uded to provide additional insight into the committees reasoning that led to a requirement and identifying the hazards that the requirement addresses. Clauses and subclauses marked with * after their number have corresponding rationale contained in Annex AA. This International Standard is a Particul

41、ar 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 standard for the safety of all medical electrical equipment used by or under the supervision of qualified personnel in the general medic

42、al and patient environment; it also contains certain requirements for reliable operation to ensure safety. The General Standard has associated Collateral Standards and Particular Standards. The Collateral Standards include requirements for specific technologies and/or hazards and apply to all applic

43、able equipment, such as medical electrical systems, EMC, radiation protection in diagnostic X-ray equipment, software, etc. The Particular Standards apply to specific equipment types, such as medical electron accelerators, high frequency surgical equipment, hospital beds, etc. NOTE Definitions of Co

44、llateral 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 following drafting conventions have been applied. This International Standard uses the same main clause titles and numbering as the General

45、 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 specified by the use of the following words. “Replacement” means that the indicated clause or subclause of the General Standard is replaced

46、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, note, table, figure) additional to the General Standard. “Amendment” means that an existing element of the General Standard is parti

47、ally 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, a particular numbering has been employed for elements added by this International Standard: subclauses, tables and figures are number

48、ed 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 print types are used: requirements, compliance with which can be verified, and definitions: roman type; notes and examples: smaller r

49、oman type; description of type of document change and test methods: italic type; BS EN ISO 18777:2009 ISO 18777:2005(E) ISO 2005 All rights reserved vii terms defined in the General Standard IEC 60601-1:1988, Clause 2, or in this Particular Standard: bold type. Throughout this International Standard, text for which a rationale is provided in Annex AA is indicated by an asterisk (*).
