Washer-disinfectors - Part 4: Requirements and tests for washer-disinfectors employing chemical disinfection for thermolabile endoscopes (ISO 15883-4:2008); German version EN ISO 15883-4:2008
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 performance 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 performance qualification on first installation), routine control and monitoring and re-validation,
periodically and after essential repairs, are also specified.
NOTE I In addition, Annex A gives guidance on an appropriate division of responsibility for the range of activities
covered by this part 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 ISO 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 the inactivation or removal
of the causative agent(s) (priori 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 react 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, disinfecting products, and also
by users.
