22、SO 23500:2014 (E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies).

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC
24、) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be no

29、hts reservedBS EN ISO 23500:2015 ISO 23500:2014 (E)IntroductionThis International Standard was developed by ISO/TC 150/SC 2. The objective was to provide users with guidance for handling water and concentrates and for the production and monitoring of dialysis fluid used for haemodialysis. The need f
30、or such guidance is based on the critical role of dialysis fluid quality in providing safe and effective haemodialysis, and the recognition that day-to-day dialysis fluid quality is under the control of the healthcare professionals who deliver dialysis therapy.Quality requirements for the water and
31、concentrates used to prepare dialysis fluid, and for that dialysis fluid, are provided in ISO 13959, ISO 13958, and ISO 11663, respectively. This International Standard does not address clinical issues that might be associated with inappropriate usage of the water, dialysis water, concentrates, or d
32、ialysis fluid. Healthcare professionals involved in the provision of treatment for kidney failure should make the final decision regarding the applications with which these fluids are used, for example, haemodialysis, haemodiafiltration, high-flux haemodialysis, and the reprocessing of dialysers, an
33、d need to be aware of the issues that the use of inappropriate fluid quality raises in each of the therapies.The equipment used in the various stages of dialysis fluid preparation is generally obtained from specialized vendors. Dialysis practitioners are generally responsible for maintaining that eq
34、uipment following its installation. Therefore, this International Standard provides guidance on monitoring and maintenance of the equipment to ensure that dialysis fluid quality is acceptable at all times. At various places throughout this International Standard, the user is advised to follow the ma
35、nufacturers instructions regarding the operation and maintenance of equipment. In those instances in which the equipment is not obtained from a specialized vendor, it is the responsibility of the user to validate the performance of the equipment in the haemodialysis setting and to ensure that approp
36、riate operating and maintenance manuals are available. Annex B provides a general description of the system components that are used for water treatment, concentrate, and dialysis fluid preparation at a dialysis facility. These descriptions are intended to provide the user with a basis for understan
37、ding why certain equipment might be required and how it should be configured; they are not intended as detailed design standards. Requirements for water treatment equipment are provided in ISO 26722.The verbal forms used in this International Standard conform to usage described in Annex H of the ISO
38、/IEC Directives, Part 2:2004. For the purposes of this International standard, the auxiliary verb: “shall” means that compliance with a requirement or a test is mandatory for compliance with this International Standard; “should” means that compliance with a requirement or a test is recommended but i
39、s not mandatory for compliance with this International Standard; “may” is used to describe a permissible way to achieve compliance with a requirement or test.This International Standard reflects the conscientious efforts of healthcare professionals, patients, and medical device manufacturers to deve
40、lop recommendations for handling water and concentrates and for the production and monitoring of dialysis fluid for haemodialysis. This International Standard is directed towards the healthcare professionals involved in the management or routine care of haemodialysis patients and responsible for the
41、 quality of dialysis fluid. The recommendations contained in this International Standard might not be applicable in all circumstances and they are not intended for regulatory application.The guidance provided by this International Standard should help protect haemodialysis patients from adverse effe
42、cts arising from known chemical and microbial contaminants that might be found in improperly prepared dialysis fluid. However, the physician in charge of dialysis has the ultimate responsibility for ensuring that the dialysis fluid is correctly formulated and meets the requirements of all applicable
43、 quality standards.The concepts incorporated in this International Standard should not be considered inflexible or static. The recommendations presented here should be reviewed periodically in order to assimilate increased understanding of the role of dialysis fluid purity in patient outcomes and te
44、chnological developments.

45、ractitioners with guidance on the preparation of dialysis fluid for haemodialysis and related therapies and substitution fluid for use in online therapies, such as haemodiafiltration and haemofiltration. As such, this International Standard functions as a recommended practice.1.2 InclusionsThis Inte
46、rnational Standard addresses the users responsibility for the dialysis fluid once the equipment used in its preparation has been delivered and installed. For the purposes of this International Standard, the dialysis fluid includes dialysis water (see 3.18 for definition) used for the preparation of
47、dialysis fluid and substitution fluid, dialysis water used for the preparation of concentrates at the users facility, as well as concentrates and the final dialysis fluid and substitution fluid.The scope of this International Standard includesa) the quality management of equipment used to treat and
48、distribute water used for the preparationof dialysis fluid and substitution fluid, from the point at which municipal water enters the dialysisfacility to the point at which the final dialysis fluid enters the dialyser or the point at whichsubstitution fluid is infused,b) equipment used to prepare co
49、ncentrate from powder or other highly concentrated media at adialysis facility, andc) preparation of the final dialysis fluid or substitution fluid from dialysis water and concentrates.NOTE Because water used to prepare dialysis fluid is commonly prepared and distributed using the same equipment as the water used to reprocess dialysers, water used to reprocess dialysers is also covered by this International Standard.1.3 ExclusionsThis International Standard does not apply to sorbent-based dialysis fluid regeneration systems that regenerate and recirculate
