27、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
28、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
29、re drafted in accordance with the 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 Internatio
30、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 part of ISO 23328 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 233
31、28-2 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 3, Lung ventilators and related equipment. ISO 23328 consists of the following parts, under the general title Breathing system filters for anaesthetic and respiratory use: Part 1: Salt test me
32、thod to assess filtration performance Part 2: Non-filtration aspects BS EN ISO 23328-2:2009ISO 23328-2:2002(E) ISO 2002 All rights reserved vIntroduction This part of ISO 23328 gives requirements for non-filtration aspects of breathing system filters (BSF). BSF are used to reduce particulates, inclu
33、ding microorganisms, in gases delivered to and exhaled from patients. BSF are exposed to various levels of humidity during clinical use. Exposure of the BSF to humidified air to simulate clinical use forms part of the test method, as it is possible that such exposure can influence the filtration per
34、formance of the BSF. A test method to assess filtration performance is found in ISO 23328-1.

35、s 1 Scope This part of ISO 23328 specifies requirements for non-filtration aspects of breathing system filters (BSF) intended for anaesthetic and respiratory use, and addresses connection ports, leakage, resistance to flow, packaging, marking and information supplied. The test method is intended for
36、 BSF used with a clinical breathing system. It is not applicable to other types of filter, e.g. those designed to protect vacuum sources or gas sample lines, to filter compressed gases, or to protect test equipment for physiological respiratory measurements. NOTE A method for assessing filtration pe
37、rformance of BSF is given in ISO 23328-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 23328. For dated references, subsequent amendments to, or revisions of, any of these publications do
