DIN EN 14349:2013-02 EN 14349:2012 (E) 4 Introduction This European Standa
32、rd specifies a surface test for establishing whether a chemical disinfectant or antiseptic has bactericidal 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 org
33、anisms and interfering substances, i.e. conditions which may influence 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, f
34、ound by this test corresponds to the chosen experimental conditions. However, for some applications, the instructions of use of a product may differ and therefore additional test conditions need to be used. DIN EN 14349:2013-02 EN 14349:2012 (E) 5 1 Scope This European Standard specifies a test meth
35、od and the minimum requirements for bactericidal activity of chemical 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. This European Standard applies to products that are used
36、in the veterinary area on non-porous surfaces without mechanical action 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 in detail the relationship of the various
37、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 2 test. This method cannot be used to eva
38、luate the activity of products against mycobacteria. 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 ed
39、ition of the referenced document (including any amendments) applies.

40、cation of European Standards for chemical disinfectants 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 from a water control, when tested
41、 in accordance with Table 1 and Clause 5 under simulated low level (3,0 g/l bovine albumin) or high level soiling (10 g/l yeast extract and 10 g/l bovine albumin) on a surface.

42、ctivity on non-porous surfaces without mechanical action in the veterinary area Test organism a) obligatory Enterococcus hirae Proteus vulgaris Pseudomonas aeruginosa Staphylococcus aureus b) additional any relevant test organism Test temperature a) obligatory 10 C + 1 C b) additional 4 C + 1 C; 20
43、C + 1 C; 40 C + 1 C Contact time a) obligatory 30 min + 10 s b) additional 1 min + 5 s; 5 min + 10 s; 60 min + 10 s Interfering substance a) obligatory low level soiling high level soiling 3,0 g/l bovine albumin 10 g/l yeast extract plus 10 g/l bovine albumin b) additional any relevant substance The
44、 obligatory contact time for surface disinfectants stated in Table 1 were chosen to enable comparison of standard conditions. The recommended contact time for the use of the product is within the responsibility of the manufacturer. NOTE For the additional conditions, the concentration defined as a r
45、esult can be lower than the one obtained under the obligatory test conditions. Any additional specific bactericidal 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. DIN EN 14349:2013-02 EN 14349:2012 (E) 7 5 Test method
46、 5.1 Principle A test suspension of bacteria mixed with interfering substance is inoculated onto the test surface and dried. After a drying time, 0,1 ml of the product is transferred to the surface, in a manner which covers the dried film. The surface is maintained at a specified temperature for a d
47、efined period of time specified in Clause 4 and 5.5.1.1. At the end of that contact time the surface is transferred to a neutralizer so that the action of the disinfectant is immediately neutralized. The numbers of surviving organisms which can be recovered from the surface is determined quantitativ
48、ely. The number of bacteria on a surface treated with water in place of the disinfectant is also determined and the reduction is calculated. The test is performed using Enterococcus hirae, Proteus vulgaris, Pseudomonas aeruginosa and Staphylococcus aureus as test organisms (Clause 4, Table 1). Addit
49、ional and optional contact times and temperatures are specified (Clause 4, Table 1). Additional interfering substances and test organisms may be used. 5.2 Materials and reagents 5.2.1 Test organisms The bactericidal activity shall be evaluated using the following strains1): Enterococcus hirae ATCC 10541; Proteus vulgaris ATCC 13315; Pseudomonas aeruginosa
