DIN EN 14180:2014-09 EN 14180:2014 (E) 4 Introduction This European Standard specifies minim

30、um requirements and test methods for sterilizers working below ambient atmospheric pressure performing a low temperature steam and formaldehyde (LTSF) process. LTSF sterilizers are primarily used for the sterilization of medical devices in health care facilities, but can also be used during the comm

31、ercial production of medical devices. LTSF processes are specified by physical parameters and verified using physical, chemical and microbiological means 8. The sterilizers operate automatically using pre-set cycles. The test methods and test equipment given could also be applicable to validation an

32、d routine control. Validation and routine control of sterilization processes are essential to ensure their efficacy. This standard does not cover validation and routine control of a LTSF process. Criteria for validation and routine control of LTSF sterilization processes are given in EN ISO 25424. A

33、t the present state of knowledge, LTSF sterilizers should not be assumed to deliver processes effectively inactivating the causative agents of spongiform encephalopathies such as scrapie, Bovine Spongiform Encephalopathy and Creutzfeld-Jakob Disease. Specific recommendations have been produced in pa

34、rticular countries for the processing of materials potentially contaminated with these agents. See also EN ISO 25424:2011, 1.2.1. Planning and design of products applying to this standard should consider not only technical issues but also the environmental impact from the product during its life-cyc

35、le. Environmental aspects are addressed in Annex F of this standard. NOTE Specifications on operator safety are addressed in EN 610101, EN 610102040 and are not repeated in this standard. EN 602041 can also give valuable guidelines. DIN EN 14180:2014-09 EN 14180:2014 (E) 5 1 Scope This European Stan

36、dard specifies requirements and tests for LTSF sterilizers, which use a mixture of low temperature steam and formaldehyde as sterilizing agent, and which are working below ambient pressure only. These sterilizers are primarily used for the sterilization of heat labile medical devices in health care

37、facilities. This European Standard specifies minimum requirements: for the performance and design of sterilizers to ensure that the process is capable of sterilizing medical devices; for the equipment and controls of these sterilizers necessary for the validation and routine control of the steriliza

38、tion processes. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
