10、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 represented on that committee. Inte
11、rnational 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 th
12、e rules given in the ISO/IEC Directives, Part 3. 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 b
13、y at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 10651 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10651-4 was prepared by the Europea
14、n Committee for Standardization (CEN) 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 Agreement).

ASTM International v Approved as an American National Standard with deviations by ASTM International Approved as an American National Standard with deviations by ASTM International ANSI/ISO 10651-4 1 Scope This Europea
24、n Standard specifies requirements for operator-powered resuscitators intended for use with all age groups and which are portable and intended to provide lung ventilation to individuals whose breathing is inadequate. Operator-powered resuscitators for infants and children are designated according to
25、body mass range and approximate age equivalent. Electrically-and gas-powered resuscitators are not covered by this European Standard. NOTE Annex B contains rationale statements for this Part of this European Standard. The clauses and subclauses which have corresponding rationale statements are marke
