4 Introduction This European Standard specifies minimum 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 may also be used during the commercial production of medical devices. LTSF processes are specified by physical parameters and verified using physical, chemical and microbiological means. The sterilizers operate automatically using pre-set cycles. The test methods and test equipment given may also be applicable to validation and 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 15424. At 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 Encephalophaty and Creutzfeld-Jakob Disease. Specific recommendations have been produced in particular countries for the processing of materials potentially contaminated with these agents. (See also EN 15424:2007 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-cycle. Environmental aspects are addressed in annex F of this standard. NOTE Risk analysis methods, e. g. in EN ISO 14971, pay attention to environmental aspects. Specifications on operator safety are addressed in EN 61010–1, #EN 61010–2–040$ and are not repeated in this standard. EN 60204–1 may also give valuable guidelines. 1 Scope This European Standard 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 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 sterilization processes. 2 Normative references !The following referenced documents are indispensable for the application of this document.
