CSA Preface 

This is the first edition of CSA ISO 8637-2, Extracorporeal systems for blood purification - Part 2: Extracorporeal blood circuit for haemodialysers, haemodiafilters and haemofilters , which is an adoption without modification of the identically titled ISO (International Standards Organization) Standard 8637-2 (first edition, 2018-07). It replaces CAN/CSA-ISO 8638:12 (adopted ISO 8638:2010), Cardiovascular implants and extracorporeal systems - Extracorporeal blood circuit for haemodialysers, haemodiafilters and haemofilters. 

CSA Group acknowledges that the adoption of this Standard was made possible, in part, by the financial support of the governments of Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Québec, Saskatchewan, and Yukon, as administered by the Canadian Agency for Drugs and Technologies in Health (CADTH). 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 

WARNING - Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this document. This document specifies requirements for the blood circuit for devices used in extracorporeal blood filtration therapies such as, but not limited to, haemodialysis, haemodiafiltration, haemofiltration and transducer protectors (integral and non-integral) intended for use in such circuits. This document does not apply to: 

- haemodialysers, haemodiafilters or haemofilters; 

- plasmafilters; 

- haemoperfusion devices; 

- vascular access devices; 

- blood pumps; 

- pressure monitors for the extracorporeal blood circuit; 

- air detection devices; 

- systems to prepare, maintain or monitor dialysis fluid; 

- systems or equipment intended to perform haemodialysis, haemodiafiltration, haemofiltration or haemoconcentration. 

NOTE 1 Requirements for haemodialysers, haemodiafilters, haemofilters and haemoconcentrators are specified in ISO 8637-1, and requirements for plasmafilters are specified in ISO 8637-3. 

NOTE 2 Extracorporeal blood tubing sets can also be used for other extracorporeal therapies such as haemoperfusion, plasmafiltration and plasma adsorption.
