EN 13727:2012+A2:2015 (E) 5 Introduction This European Standard specifies a suspension test for establishing whether a chemical disinfectant or an antiseptic has a bactericidal activity in the area and fields described in the scope. This labora
41、tory 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 utilization concentration of the chemical disinfectant or antis
42、eptic found by this test corresponds to the chosen experimental conditions. BS EN 13727:2012+A2:2015EN 13727:2012+A2:2015 (E) 6 1 Scope This European Standard specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectant and antiseptic products that form a h
43、omogeneous, 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 test organi
44、sms 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 or other
45、 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 of nursin
46、g 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 conditions in
47、 which they are used. NOTE 2 This method corresponds to a phase 2 step 1 test. NOTE 3 This method cannot be used to evaluate the activity of products against Legionella in watersystems against mycobacteria and against bacterial spores. EN 14885 specifies in detail the relationship of the various tes
48、ts to one another and to “use recommendations”. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
