20、006+A2:2009) has been prepared by Technical Committee CEN/TC 102 “Sterilizers for medical purposes”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Novemb
21、er 2009 and conflicting national standards shall be withdrawn at the latest by March 2010. This document includes Amendment 1, approved by CEN on 2008-02-04 and Amendment 2, approved by CEN on 2009-04-05. This document supersedes #EN 285:2006+A1:2008$. The start and finish of text introduced or alte
22、red by amendment is indicated in the text by tags ! “ and # $. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informati
23、ve Annex ZA, which is an integral part of this document. This document does not specify requirements for the validation and routine control of sterilization by moist heat. A European Standard specifying requirements for the validation and routine control of sterilization by moist heat was prepared b
24、y CEN/TC 204 “Sterilization of medical devices“, see EN 554 (currently under revision, see prEN ISO 17665). The performance requirements specified in this document are not intended for the process to be effective in inactivating the causative agents of spongiform encephalopathies such as scrapie, bo
25、vine spongiform encephalopathy and Creutzfeld-Jakob disease. However, some national regulations require the use of modified steam processes as part of a general prion decontamination programme. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following c
26、ountries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

28、specifies requirements and the relevant tests for large steam sterilizers primarily used in health care for the sterilization of medical devices and their accessories contained in one or more sterilization modules. The test loads described in this European Standard are selected to represent the majo
29、rity of loads (i.e. wrapped goods consisting of metal, rubber and porous materials) for the evaluation of general purpose steam sterilizer for medical devices. However, specific loads (e.g. heavy metal objects or long and/or narrow lumen) will require the use of other test loads. Large steam sterili
30、zers can also be used during the commercial production of medical devices. 1.2 This European Standard is not applicable to steam sterilizers designed to process a size of load less than one sterilization module or having a chamber volume less than 60 l. 1.3 This European Standard does not describe a
31、 quality assurance system for the control of all stages of the manufacture of the sterilizer. NOTE Attention is drawn to the standards for quality management systems e.g. EN ISO 13485. 1.4 Planning and design of products applying to this European Standard should consider the environmental impact fro
32、m the product during its life cycle. Environmental aspects are addressed in Annex A. NOTE Additional aspects of environmental impact are addressed in EN ISO 14971. 2 Normative references The following referenced documents are indispensable for the application of this document.
