30、ISO 15883-3:2009 (E) Introduction It is recommended that this Introduction be read in conjunction with the introduction to ISO 15883-1. This part of ISO 15883 is the third of a series of standards specifying the performance of washer-disinfectors and specifies the general requirements for performanc

31、e applicable to bedpan washer-disinfectors. The requirements given in this part apply to washer-disinfectors used for emptying, flushing, cleaning and thermally disinfecting human waste containers intended for re-use such as: portable sanitary pans; supports for single-use bed pans; hospital bowls;

32、urine bottles; suction bottles; and products similar to the above and used for similar purposes. Fields of application within the scope of the ISO 15883 series of standards include laboratory, veterinary, dental and pharmaceutical applications and other specific applications, such as washer-disinfec

33、tors 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 parts the ISO 15883 series of standards. Bedpan washer disinfectors are l

34、oaded manually. In order to reduce the risk of spillage and the generation of aerosols most machines incorporate means to empty human waste containers automatically e.g. by the action of closing the door. Where equipment does not provide automatic emptying facilities, extra care is needed by the use

35、r to avoid exposure to human waste and contamination of the work environment including the generation of aerosols. The reliability of a bedpan washer-disinfector may be adversely affected if the machine is connected to a poorly designed or constructed drainage system. The purchaser is therefore reco

36、mmended to ensure that the drainage system complies with the manufacturers recommendations in all respects. Safety requirements for washer-disinfectors 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 washe

37、r-disinfectors: a) note that until verifiable European criteria are adopted, existing national 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 wit

38、hout restriction in any of the member states of the EU or EFTA. 4 DIN EN ISO 15883-3:2009-09 EN ISO 15883-3:2009 (E) 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

39、 containers used to hold human waste for disposal by one operating cycle. This part of ISO 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.

44、aximum range of temperatures permitted on the load items, see 4.1.4 of this part of ISO 15883); subclause 5.3.1.2 (which refers to the use of a machine purging and disinfection); subclause 5.7.4 (which refers to verification of the dose of process chemical admitted); subclause 5.7.5 (which specifies

45、 the accuracy and reproducibility of chemical dosing systems); subclause 5.8 (which refers to load temperature protection); subclause 5.9 (which refers to control of temperatures on the load and chamber walls, see 4.5.3 and 4.5.4 of this part of ISO 15883); subclause 6.8.5 (which refers to tests for

46、 load temperature protection); subclause 6.10.3.2 (which refers to protein residue tests, see also ISO 15883-1:2006, Table A.1 (load, 6.10.3) and Annex A of this part of ISO 15883). 4.1.2 The WD shall be designed to process either one type of human waste container or a variety of types of human wast

47、e container and the re-usable supports for single-use bedpans. NOTE This can require the use of two or more types of load carrier. 4.1.3 The WD shall be designed to process either one human waste container per cycle, or several human waste containers per cycle. 4.1.4 The temperature attained on the

48、surfaces of the load during the disinfection stage shall not be less than the disinfection temperature. 4.2 Chemical dosing systems 4.2.1 Provision shall be made for the installation of a chemical dosing system, when specified by the purchaser, to allow for the injection of a descalant, detergent an

49、d/or rinse aid. 4.2.2 The means to control the volume of additive(s) admitted shall be adjustable and shall deliver the set volume to an accuracy of 10 % or better. 4.2.3 The WD shall either be fitted with means to ensure that a fault is indicated when insufficient process chemical(s) has/have been admitted, or it shall be possible for the operator to visually verify that the required amount of process chemical(s) has/have been used. 6 DIN EN ISO 15883-3:2009-09 EN ISO 15883-3:2009 (E) 4.3 Empty
