This European Standard shall be given the status of a national standard,

23、 either by publication of an identical text or by endorsement, at the latest by March 2014, and conflicting national standards shall be withdrawn at the latest by March 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and

24、/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13624:2003. The document was revised to adapt it to the latest state of science, to correct errors and ambiguities, to harmonise the structure and wording with other tests of CEN/TC 2

25、16 existing or in preparation and to improve the readability of the standard and thereby make it more understandable. The following is a list of significant technical changes since the last edition: The Scope was expanded for the following fields of application within the medical area, i.e. products

26、 for surgical and/or hygienic handrub and/or handwash and disinfectants for other surfaces than instrument surfaces. “Obligatory test conditions” were replaced by “minimum test conditions” (test temperatures and contact times can be chosen within limits) that have to be performed to pass the test. A

27、n additional modified method is described to test ready-to-use products in a higher concentration than 80 %, i.e. 97 %. The quality of the cultured conidiospores of Aspergillus brasiliensis is described in greater detail (media, limits and the control methods) resulting from work done in WG 3 of CEN

28、/TC 216. The neutralization time was shortened to 10 s for products with contact times of 10 min or less. The Annex ZA was reformulated to more accurately describe the relationship with the Medical Device Directive. Data obtained using the former version of EN 13624 may still be used, if the quality

29、 of the conidiospores of Aspergillus brasiliensis had been controlled and had met the requirements in this standard (5.4.1.4.2). 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

30、Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgiu

31、m, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerl

32、and, Turkey and the United Kingdom. DIN EN 13624:2013-12 EN 13624:2013 (E) 4 Introduction This European Standard specifies a suspension test for establishing whether a chemical disinfectant or an antiseptic has a fungicidal or yeasticidal activity in the area and fields described in the scope. This

33、laboratory test takes into account practical conditions of application of the product including contact time, temperature, test organisms and interfering substances, i.e. conditions which may influence its action in practical situations. Each utilisation concentration of the chemical disinfectant or

34、 antiseptic found by this test corresponds to the chosen experimental conditions. DIN EN 13624:2013-12 EN 13624:2013 (E) 5 1 Scope This European Standard specifies a test method and the minimum requirements for fungicidal or yeasticidal activity of chemical disinfectant and antiseptic products that

35、form a homogeneous, physically stable preparation when diluted with hard water, or - in the case of ready-to-use products - with water. Products can only be tested at a concentration of 80 % or less (97 % with a modified method for special cases) as some dilution is always produced by adding the tes

36、t organisms and interfering substance. This European Standard applies to products that are used in the medical area in the fields of hygienic handrub, hygienic handwash, surgical handrub, surgical handwash, instrument disinfection by immersion, and surface disinfection by wiping, spraying, flooding

37、or other means. This European Standard applies to areas and situations where disinfection or antisepsis is medically indicated. Such indications occur in patient care, for example: in hospitals, in community medical facilities and in dental institutions; in clinics of schools, of kindergartens and o

38、f nursing homes; and may occur in the workplace and in the home. It may also include services such as laundries and kitchens supplying products directly for the patients. NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the condi

39、tions in which they are used. NOTE 2 This method corresponds to a phase 2 step 1 test. EN 14885 specifies in detail the relationship of the various tests to one another and to “use recommendations”. 2 Normative references The following documents, in whole or in part, are normatively referenced in th

40、is document and are indispensable for its application. For dated references, only the edition cited applies.
