19、) 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 latest by November

20、2013, and conflicting national standards shall be withdrawn at the latest by November 2013.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 patent ri

21、ghts. This document includes Amendment 1, approved by CEN on 2013-03-28. This document supersedes !EN 1650:2008“. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. This European Standard was revised to include the results of a collaborative trial (A

22、NDISTAND), to correct obvious errors and ambiguities, to harmonize the structure and wording with other quantitative suspension tests of CEN/TC 216 (existing or in preparation), and to improve the readability of the standard and thereby make it more understandable. According to the CEN/CENELEC Inter

23、nal Regulations, the national 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, Ir

24、eland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 1650:2008+A1:2013 EN 1650:2008+A1:2013 (E)3 Introduction This European Standard specifies a suspension test for est

25、ablishing whether a chemical disinfectant or antiseptic has or does not have a fungicidal or yeasticidal activity in the 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 i

26、nterfering substance, 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 found by this t

27、est corresponds to defined experimental conditions. However, for some applications the recommendations of use of a product may differ and therefore additional test conditions should be used. BS EN 1650:2008+A1:2013 EN 1650:2008+A1:2013 (E)4 1 Scope This document specifies a test method and the minim

28、um requirements for fungicidal or yeasticidal 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. Products can only be tested at a concentration of 80 % o

29、r less as some dilution is always produced by adding the test organisms and interfering substance. This document applies to products that are used in food, industrial, domestic and institutional areas excluding areas and situations where disinfection is medically indicated and excluding products use

30、d on living tissues except those for hand hygiene in the above considered areas. The following areas are at least included: a) processing, distribution and retailing of: 1) food of animal origin: 2) food of vegetable origin: milk and milk products; beverages; meat and meat products; fruits, vegetabl

31、es and derivatives (including sugar, distillery .); fish, seafood, and related products; flour, milling and baking; eggs and egg products; animal feeds; animal feeds; etc. etc. b) institutional and domestic areas: catering establishments; public areas; public transports; schools; nurseries; shops; s

32、ports rooms; waste containers (bins .); hotels; dwellings; clinically non-sensitive areas of hospitals; offices; etc. BS EN 1650:2008+A1:2013 EN 1650:2008+A1:2013 (E)5 c) other industrial areas: packaging material; biotechnology (yeast, proteins, enzymes, .); pharmaceutical; cosmetics and toiletries

33、; textiles; space industry, computer industry; etc. EN 14885 specifies 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 i

34、n which they are used. NOTE 2 This method corresponds to a phase 2 step 1 test. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the re

35、ferenced document (including any amendments) applies.

37、onstrate a reduction of at least a 4 decimal log (lg) when diluted with hard water (5.2.2.7) or - in the case of ready-to-use products - with water (5.2.2.2) and tested in accordance with Clause 5 under simulated clean conditions (0,3 g/l bovine albumin solution - 5.2.2.8.2) or simulated dirty condi

38、tions (3 g/l bovine albumin solution - 5.2.2.8.3) according to its practical applications and under the other obligatory test conditions (one or two selected test organisms, 20 C, 15 min). The fungicidal activity shall be evaluated using the following two test organisms: Candida albicans (vegetative

39、 cells); BS EN 1650:2008+A1:2013 EN 1650:2008+A1:2013 (E)6 Aspergillus niger (spores). The yeasticidal activity shall be evaluated using the following test organism: Candida albicans (vegetative cells); Where indicated, additional specific fungicidal or yeasticidal activity shall be determined apply

40、ing other contact times, temperatures, interfering substances and test organisms (in accordance with 5.2.1, 5.2.2.8 and 5.5.1.1) in order to take into account intended specific use conditions. NOTE For these additional conditions, the concentration defined as a result can be lower than the one obtai

41、ned under the obligatory test conditions. 5 Test method 5.1 Principle 5.1.1 A sample of the product as delivered and/or diluted with hard water (or water for ready to use products) is added to a test suspension of fungi (yeast cells or mould spores) in a solution of an interfering substance. The mix

42、ture is maintained at (20 1) C for 15 min 10 s (obligatory test conditions). At the end of this contact time, an aliquot is taken, and the fungicidal and/or the fungistatic activity in this portion is immediately neutralized or suppressed by a validated method. The method of choice is dilution-neutr

43、alization. If a suitable neutralizer cannot be found, membrane filtration is used. The numbers of surviving fungi in each sample are determined and the reduction is calculated. 5.1.2 The test is performed using the vegetative cells of Candida albicans and the spores of Aspergillus niger (fungicidal

44、activity) or only the vegetative cells of Candida albicans (yeasticidal activity) as test organisms (obligatory test conditions). 5.1.3 Additional and optional contact times and temperatures are specified. Additional test organisms can be used. 5.2 Materials and reagents 5.2.1 Test organisms The fun

45、gicidal activity shall be evaluated using the following strains as test organisms:1) Candida albicans ATCC 10231 Aspergillus niger ATCC 16404 The yeasticidal activity shall be evaluated using only Candida albicans. NOTE See annex A for strain references in some other culture collections. The require

46、d incubation temperature for these test organisms is (30 1) C (5.3.2.3). If required for specific applications, additional strains may be chosen from, e.g. for breweries: 1)The ATCC numbers are the collection numbers of strains supplied by the American Type Culture Collection (ATCC).
