CSA Preface This is the first edition of CAN/CSA-Z23328-1, Breathing system filters for anaesthetic and respiratory use — Part 1: Salt test method to assess filtration performance, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 23328-1 (first edition, 2003-08-15). At the time of publication, ISO 23328-1:2003 is available from ISO in English only. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Respiratory Technology, under the jurisdiction of the Technical Committee on Anaesthetic Equipment, Respiratory Technology, and Critical Care Equipment and the Strategic Steering Committee on Health Care Technology, and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada. This part of ISO 23328 gives a short-term airborne sodium chloride particle challenge test method for assessing the filtration performance of breathing system filters (BSF) intended for the filtration of respired gases. Scope This part of ISO 23328 is applicable to 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 Non-filtration aspects of BSF are addressed in ISO 23328-2.
