14、v ISO 2006 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intere
15、sted in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
16、Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the tec
17、hnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
18、 shall not be held responsible for identifying any or all such patent rights. ISO 15883-3 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 102, Sterilizers for medical purposes, in collaboration with Technical Committee ISO/TC 198, Sterilization of health c
19、are products, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This part of
23、ISO 15883 is the third of a series of standards specifying the performance of washer-disinfectors and specifies the general requirements for performance applicable to bedpan washer-disinfectors. The requirements given in this part apply to washer-disinfectors used for emptying, flushing, cleaning an
24、d thermally disinfecting human waste containers intended for re-use such as: portable sanitary pans; supports for single-use bed pans; hospital bowls; urine bottles; suction bottles; and products similar to the above and used for similar purposes. Fields of application within the scope of the ISO 15
25、883 series of standards include laboratory, veterinary, dental and pharmaceutical 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. Requi
26、rements for washer-disinfectors for other applications are specified in other parts the ISO 15883 series of standards. Bedpan washer disinfectors are loaded manually. In order to reduce the risk of spillage and the generation of aerosols most machines incorporate means to empty human waste container
27、s automatically e.g. by the action of closing the door. Where equipment does not provide automatic emptying facilities, extra care is needed by the user to avoid exposure to human waste and contamination of the work environment including the generation of aerosols. The reliability of a bedpan washer
28、-disinfector may be adversely affected if the machine is connected to a poorly designed or constructed drainage system. The purchaser is therefore recommended to ensure that the drainage system complies with the manufacturers recommendations in all respects. Safety requirements for washer-disinfecto
29、rs are given in IEC 61010-2-045. In respect of 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 national regulations concerning the use and/or the characterist
30、ics 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.

33、 for human waste containers 1 Scope This part of ISO 15883 specifies particular requirements for washer-disinfectors (WD) that are intended to be used for emptying, flushing, cleaning and thermal disinfection of containers used to hold human waste for disposal by one operating cycle. This part of IS
34、O 15883 is to be applied in conjunction with ISO 15883-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inc
35、luding any amendments) applies.
