20、eword This European Standard (EN 1040:2005) 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

21、by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard supersedes EN 1040:1997. It was revised to correct obvious errors and ambiguities, to harmonize the structure and wording with other quantitative suspe

22、nsion tests of CEN TC 216 existing or in preparation and to improve the readability and with that the understandability of the standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: A

24、Wed Apr 12 09:12:03 BST 2006, Uncontrolled Copy, (c) BSIEN 1040:2005 (E) 4 Introduction This European Standard specifies a suspension test for establishing whether a chemical disinfectant or antiseptic does or does not have a basic bactericidal activity in the fields described in the scope. The acce

25、ptability of a product for a defined purpose cannot be determined from this test method. Therefore products are subjected to further testing by relevant tests specified in European Standards in order to evaluate their activity under conditions appropriate to their intended use. These European Standa

26、rds have been or will be developed by CEN/TC 216. Licensed Copy: Wang Bin, na, Wed Apr 12 09:12:03 BST 2006, Uncontrolled Copy, (c) BSIEN 1040:2005 (E) 5 1 Scope This European Standard specifies a test method and the minimum requirements for basic bactericidal activity of chemical disinfectant and a

27、ntiseptic products that form a homogeneous, physically stable preparation when diluted with water. Products can only be tested at a concentration of 80 % or less as some dilution is always produced by adding the test organisms and water. This European Standard applies to active substances (antibacte

28、rial biocides) and to formulations under development that are planned to be used in food, industrial, domestic and institutional, medical and veterinary areas. It applies also to the evaluation of bactericidal activity of chemical antiseptics and disinfectants when appropriate standards are not avai

29、lable. NOTE 1 This European Standard does not evaluate the activity of a product for an intended use. NOTE 2 This method corresponds to a phase 1 test (Annex F). 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated refer

30、ences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12353, Chemical disinfectants and antiseptics Preservation of microbial strains used for the determination of bactericidal and fungicidal activity 3 Ter

31、ms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 product chemical agent or formulation used as chemical disinfectant or antiseptic 3.2 bactericide product that kills vegetative bacteria under defined conditions NOTE The adjective derived f

32、rom “bactericide” is “bactericidal”. 3.3 bactericidal activity capability of a product to produce a reduction in the number of viable bacterial cells of relevant test organisms under defined conditions 3.4 bacteriostatic activity capability of a product to inhibit the growth of bacteria under define

33、d conditions Licensed Copy: Wang Bin, na, Wed Apr 12 09:12:03 BST 2006, Uncontrolled Copy, (c) BSIEN 1040:2005 (E) 6 4 Requirements The product shall demonstrate at least a 5 decimal log (lg) reduction when tested in accordance with Clause 5. The bactericidal activity shall be evaluated using at lea

34、st the following obligatory experimental test conditions: two test organisms (Pseudomonas aeruginosa and Staphylococcus aureus), 20 C, 5 min. Where indicated, bactericidal activity could be determined applying additional contact times, temperatures and test organisms in accordance with 5.2.1 and 5.5

35、.1.1. NOTE 1 For these additional conditions, the concentration defined as a result can be lower than the one obtained under the obligatory test conditions. NOTE 2 At the concentration defined as a result, it is not necessary to demonstrate a 5 lg reduction with the obligatory test conditions. 5 Tes

36、t method 5.1 Principle 5.1.1 A sample of the product as delivered (highest test concentration = 80 %) and/or diluted with water is added to a test suspension of bacteria. The mixture is maintained at (20 1) C for 5 min 10 s (obligatory test conditions). At the end of this contact time, an aliquot is

37、 taken; the bactericidal and/or the bacteriostatic activity in this portion is immediately neutralized or suppressed by a validated method. The method of choice is dilution-neutralization. If a suitable neutralizer cannot be found, membrane filtration is used. The numbers of surviving bacteria in ea

38、ch sample are determined and the reduction is calculated. 5.1.2 The test is performed using Pseudomonas aeruginosa and Staphylococcus aureus as test organisms (obligatory test conditions). 5.1.3 Additional and optional contact times and temperatures are specified. Additional test organisms can be us

39、ed. 5.2 Materials and reagents 5.2.1 Test organisms The bactericidal activity shall be evaluated using the following strains as test organisms:1) Pseudomonas aeruginosa ATCC 15442; Staphylococcus aureus ATCC 6538. NOTE See Annex A for strain references in some other culture collections. 1)The ATCC n

40、umbers are the collection numbers of strains supplied by the American Type Culture Collection (ATCC). This information is given for the convenience of users of this European Standard and does not constitute an endorsement by CEN of the product named. Licensed Copy: Wang Bin, na, Wed Apr 12 09:12:03

41、BST 2006, Uncontrolled Copy, (c) BSIEN 1040:2005 (E) 7 The required incubation temperature for these test organisms is (36 1) C or (37 1) C (5.3.2.3). The same temperature (either 36 C or 37 C) shall be used for all incubations performed during a test and its control and validation. If additional te

42、st organisms are used, they shall be incubated under optimum growth conditions (temperature, time, atmosphere, media) noted in the test report. If the additional test organisms selected do not correspond to the specified strains, their suitability for supplying the required inocula shall be verified

43、. If these additional test organisms are not classified at a reference centre, their identification characteristics shall be stated. In addition, they shall be held by the testing laboratory or national culture collection under a reference for five years. 5.2.2 Culture media and reagents 5.2.2.1 Gen

44、eral All weights of chemical substances given in this European Standard refer to the anhydrous salts. Hydrated forms may be used as an alternative, but the weights required shall be adjusted to allow for consequent molecular weight differences. The reagents shall be of analytical grade and/or approp

45、riate for microbiological purposes. They shall be free from substances that are toxic or inhibitory to the test organisms. NOTE 1 To improve reproducibility, it is recommended that commercially available dehydrated material is used for the preparation of culture media. The manufacturers instructions

46、 relating to the preparation of these products should be rigorously followed. NOTE 2 For each culture medium and reagent, a limitation for use should be fixed. 5.2.2.2 Water The water shall be freshly glass-distilled water and not demineralized water. Sterilize in the autoclave 5.3.2.1a). NOTE 1 Ste

47、rilization is not necessary if the water is used e.g. for preparation of culture media and subsequently sterilized. NOTE 2 If distilled water of adequate quality is not available, water for injections (see bibliographic reference 1) can be used. 5.2.2.3 Tryptone Soya Agar (TSA) Tryptone soya agar, c

After sterilization the pH of the medium shall be equivalent to (7,2 0,2) when measured

49、 at (20 1) C. NOTE In case of encountering problems with neutralization (5.5.1.2 and 5.5.1.3) it may be necessary to add neutralizer to the TSA. Annex B gives guidance on the neutralizers that may be used.
