CSA Preface This is the first edition of CSA Z23500-3, Preparation and quality management of fluids for haemodialysis and related therapies — Part 3: Water for haemodialysis and related therapies , which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 23500-3 (first edition, 2019-02). It replaces CAN/CSA-ISO 13959:15 (adopted ISO 13959:2014), Water for haemodialysis and related therapies. For brevity, this Standard will be referred to as “CSA Z23500-3” throughout. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Quality Management for Kidney Dialysis, under the jurisdiction of the CSA Technical Committee on Kidney Dialysis and the CSA Strategic Steering Committee on Health and Well-being, 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 document specifies minimum requirements for water to be used in haemodialysis and related therapies. This document includes water to be used in the preparation of concentrates, dialysis fluids for haemodialysis, haemodiafiltration and haemofiltration, and for the reprocessing of haemodialysers. This document excludes the operation of water treatment equipment and the final mixing of treated water with concentrates to produce dialysis fluid. Those operations are the sole responsibility of dialysis professionals. This document does not apply to dialysis fluid regenerating systems.
