NOTE 1 In addition, Annex A gives guidance on an appropriate division of responsibility for the range of activities
covered in this Standard.
NOTE 2 WDs complying with this Part of ISO 15883 can also be used for cleaning and chemical disinfection of other
thermo-labile 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/FDIS 15883-1:2005, 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) (prion protein) of Transmissible Spongiform Encephalopathies.
NOTE 3 If it is considered that prion protein may 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.
