28、t (EN 14204:2012) has been prepared by Technical Committee CEN/TC 216 “Chemical disinfectants and antiseptics”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the lat

29、est by May 2013, and conflicting national standards shall be withdrawn at the latest by May 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such pat

30、ent rights. This document supersedes EN 14204:2004. Data obtained using the former version of EN 14204 may still be used. This document was revised to correct obvious errors and ambiguities, to harmonize the structure and wording with other quantitative suspension tests of CEN/TC 216 (existing or in

31、 preparation), and to improve the readability of the standard and thereby make it more understandable. The following technical changes have been made: Membrane filtration (5.5.3) method and associated media and equipment have been added. According to the CEN/CENELEC Internal Regulations, the nationa

32、l standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithua

33、nia, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 14204:2013-02 EN 14204:2012 (E) 4 Introduction This European Standard specifies a suspension test for establishing whether a chemical disinfec

34、tant or antiseptic has mycobactericidal activity in the area and fields described in the scope. This 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 influen

35、ce its action in practical situations. The conditions are intended to cover general purposes and to allow reference between laboratories and product types. Each utilization concentration of the chemical disinfectant or antiseptic, found by this test corresponds to the chosen experimental conditions.

36、 However, for some applications the instructions of use of a product may differ and therefore additional test conditions need to be used. DIN EN 14204:2013-02 EN 14204:2012 (E) 5 1 Scope This European Standard specifies a test method and the minimum requirements for mycobactericidal activity of chem

37、ical disinfectant and antiseptic products that 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, as some dilution is always produced by adding the test org

38、anisms and interfering substance. This European Standard applies to products that are used in the veterinary area i.e. in the breeding, husbandry, production, transport and disposal of all animals except when in the food chain following death and entry to the processing industry. EN 14885 specifies

39、in detail the relationship of the various tests to one another and to “use recommendations”. NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used. NOTE 2 This method corresponds to a phase 2 step

40、 1 test. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including

41、any amendments) applies.

42、sinfectants and antiseptics 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 14885 apply. 4 Requirements The product shall demonstrate at least a 4 decimal log (lg) reduction when tested in accordance with Table 1 and Clause 5 under simulated low level

43、 (3,0 g/l bovine albumin) or high level soiling (10 g/l yeast extract and 10 g/l bovine albumin). DIN EN 14204:2013-02 EN 14204:2012 (E) 6 Table 1 - Obligatory and additional test conditions Test conditions Mycobactericidal activity Test organism a) obligatory Mycobacterium avium b) additional any r

44、elevant test organism Test temperature a) obligatory 10C 1C b) additional 4C 1C; 20C 1C; 40C 1C Contact time a) obligatory 60 min 10 sab) additional 1 min 5 s; 5 min 10 s; 10 min 10 s, 15 min 10 s, 30 min 10 s, 120 min 10 s Interfering substance a) obligatory low level soiling high level soiling 3,0

45、 g/l bovine albumin 10 g/l yeast extract plus 10 g/l bovine albumin b) additional any relevant substance NOTE For the additional conditions, the concentration defined as a result can be lower than the one obtained under the obligatory test conditions.a The obligatory contact time for disinfectants s

46、tated in Table 1 was chosen to enable comparison of standard conditions. The referenced test conditions are by no means intended as requirements for the use of a product. The recommended contact time for the use of the product is within the responsibility of the manufacturer. Any additional specific

47、 mycobactericidal activity shall be determined in accordance with 5.2.1 and 5.5.1.1 in order to take into account intended specific use conditions. 5 Test method 5.1 Principle A sample of the product as delivered and/or diluted in hard water (or water for ready to use products) is added to a test su

48、spension of mycobacteria in a solution of an interfering substance. The mixture is maintained at (10 1) C for 60 min 10 s. At the end of this contact time, an aliquot is taken and the mycobactericidal action in this portion is immediately neutralized or suppressed by a validated method. The number o

49、f surviving mycobacteria in each sample is determined and the reduction in viable counts calculated. DIN EN 14204:2013-02 EN 14204:2012 (E) 7 The test is performed using Mycobacterium avium as the test organism (Clause 4, Table 1). Additional and optional contact times and temperatures are specified (Clause 4, Table 1). Additional
