CSA Preface This is the first edition of CSA ISO 23328-1, 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). The original designation of this Standard was CSA Z23328-1:04. The designation has been corrected to read "CSA ISO 23328-1:04" throughout. For brevity, this Standard will be referred to as "CSA ISO 23328-1" throughout. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Perioperative Safety, under the jurisdiction of the CSA Strategic Steering Committee on Health Care Technology, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 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. 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.
