34、:2009-09 EN ISO 15883-4:2009 (E) Introduction It is recommended that this introduction be read in conjunction with the introduction to ISO 15883-1. The washer-disinfectors specified in this part of ISO 15883 are intended to process devices which can be immersed in water or aqueous solutions. For som

35、e devices this will require that, prior to processing, relevant parts of the device are protected from immersion in accordance with the device manufacturers operating instructions. Fields of application within the scope of the ISO 15883 series include laboratory, veterinary, dental and pharmaceutica

36、l applications and other specific applications, such as washer-disinfectors for bedsteads and transport carts and the disinfection of crockery and cutlery intended for use with immunologically compromised patients. Requirements for washer-disinfectors for other applications are specified in other pa

37、rts of ISO 15883. Safety requirements for washer-disinfectors are given in IEC 61010-2-040. With respect to the potential adverse effects on the quality of water intended for human consumption caused by the washer-disinfectors: a) note that, until verifiable European criteria are adopted, existing n

38、ational regulations concerning the use and/or the characteristics of the washer-disinfectors remain in force; b) this part of ISO 15883 provides no information as to whether the washer-disinfectors may be used without restriction in any of the member states of the EU or EFTA. 5 DIN EN ISO 15883-4:20

39、09-09 EN ISO 15883-4:2009 (E) 1 Scope This part of ISO 15883 specifies the particular requirements, including performance, for washer-disinfectors (WDs) that are intended to be used for cleaning and chemical disinfection of thermolabile endoscopes. This part of ISO 15883 also specifies the performan

40、ce requirements for the cleaning and disinfection of the washer-disinfector and its components and accessories which may be required to achieve the necessary performance. The methods, instrumentation and instructions required for type testing, works testing, validation (installation, operational and

41、 performance qualification on first installation), routine control and monitoring and re-validation, periodically and after essential repairs, are also specified. NOTE 1 In addition, Annex A gives guidance on an appropriate division of responsibility for the range of activities covered by this part

42、of ISO 15883. NOTE 2 WDs complying with this part of ISO 15883 can also be used for cleaning and chemical disinfection of other thermolabile re-usable medical devices for which the device manufacturer has recommended this method of disinfection. WDs complying with the requirements of this part of IS

43、O 15883 are not intended for cleaning and disinfection of medical devices, including endoscopic accessories, which are heat stable and can be disinfected or sterilized by thermal methods (see ISO 15883-1:2006, 4.1.5). The specified performance requirements of this part of ISO 15883 may not ensure th

44、e inactivation or removal of the causative agent(s) (prion protein) of transmissible spongiform encephalopathies. NOTE 3 If it is considered that prion protein might be present, particular care is needed in the choice of disinfectants and cleaning agents to ensure that the chemicals used do not reac

45、t with the prion protein in a manner that may inhibit its removal or inactivation from the load or washer-disinfector. This part of ISO 15883 can be used by prospective purchasers and manufacturers as the basis of agreement on the specification of WD manufacturers of endoscopes, cleaning products, d

46、isinfecting products, and also by users. 6 DIN EN ISO 15883-4:2009-09 EN ISO 15883-4:2009 (E) 2 Normative references The following referenced documents are indispensable for the application of this document.
