33、ISO 2002 All rights reservedForeword ISO (the International Organization for Standardization) 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 intereste
34、d in a subject for which a technical committee has been established has the right to be represented 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 Com
35、mission (IEC) on all matters of electrotechnical standardization. International Standards are 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 techni
36、cal committees are circulated to the member bodies for voting. Publication as an International 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 right
37、s. ISO shall not be held responsible for identifying any or all such patent rights. ISO 23328-2 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 gener
38、al title Breathing system filters for anaesthetic and respiratory use: Part 1: Salt test method to assess filtration performance Part 2: Non-filtration aspects ISO 23328-2:2002(E) ISO 2002 All rights reserved vIntroduction This part of ISO 23328 gives requirements for non-filtration aspects of breat
39、hing system filters (BSF). BSF are used to reduce particulates, including 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,
40、as it is possible that such exposure can influence the filtration performance of the BSF. A test method to assess filtration performance is found in ISO 23328-1.

41、 2: Non-filtration aspects 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 te
42、st method is intended for 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 fo
43、r assessing filtration performance 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
