20、his document supersedes EN 13697:2001. The changes between this edition and EN 13697:2001 are the following: interfering substance has been changed from 0,03 % bovine albumin to 0,85 % skimmed milk (see Clause 4, Table 1) for Pseudomonas aeruginosa under clean conditions only; A. brasiliensis (ex A.

21、 niger) spore preparation has been updated in order to harmonize this step with the QST fungicidal test method amendment issued in 2012 (see 5.4.1.3 b); Calculations of the weighed means and of the results have been modified in order to be harmonized with new CEN TC 216 standards (see 5.4.1.5, 5.5.2

22、, 5.5.3 and 5.6); Other paragraphs have been harmonized to new CEN TC 216 standards (e.g. preparation of hard water, 5.2.2.7). Results obtained from the previous standard for Aspergillus niger need to be repeated to take into account the new spore morphology requirement and the change in interfering

23、 substance. According to the CEN-CENELEC Internal Regulations, the national standards organizations 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,

BS EN 13697:2015EN 13697:2015 (E) 4 Introduction This European Standard des

25、cribes a surface test method for establishing whether a product proposed as a disinfectant in the fields described in Clause 1 has or does not have bactericidal and/or fungicidal or yeasticidal activity on non-porous surfaces. This European Standard has been revised in order to modify the interferin

26、g substance under “clean conditions” adopted for P. aeruginosa; in order to modify the calculation of N, NC, NT, Nc, Na and consequently the final results and to harmonize the standard with the other recent CEN TC 216 standards. The laboratory test closely simulates practical conditions of applicati

27、on. Chosen conditions (contact time, temperature, organisms on surfaces .) reflect parameters which are found in practical situations including conditions which may influence the action of disinfectants. Each use concentration found from this test corresponds to defined experimental conditions. The

28、conditions are intended to cover general purposes and to allow reference between laboratories and product types. However, for some applications the recommendations of use of a product can differ and therefore additional test conditions need to be used. BS EN 13697:2015EN 13697:2015 (E) 5 1 Scope Thi

29、s European Standard specifies a test method (phase 2/step 2) and the minimum requirements for bactericidal and/or fungicidal or yeasticidal activity of chemical disinfectants that form a homogeneous physically stable preparation in hard water or in the case of ready-to-use products with water in foo

30、d, industrial, domestic and institutional areas, excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues. The scope of this European Standard applies at least to the following: a) Processing, distribution and retailing of: 1) Food of ani

31、mal origin: i) milk and milk products; ii) meat and meat products; iii) fish, seafood and products; iv) eggs and egg products; v) animal feeds; vi) etc. 2) Food of vegetable origin: i) beverages; ii) fruits, vegetables and derivatives (including sugar distillery); iii) flour, milling and backing; iv

32、) animal feeds; v) etc. b) Institutional and domestic areas: 1) catering establishments; 2) public areas; 3) public transports; 4) schools; 5) nurseries; 6) shops; 7) sports rooms; 8) waste container (bins); BS EN 13697:2015EN 13697:2015 (E) 6 9) hotels; 10) dwellings; 11) clinically non sensitive a

33、reas of hospitals; 12) offices; 13) etc. c) Other industrial areas: 1) packaging material; 2) biotechnology (yeast, proteins, enzymes.); 3) pharmaceutical; 4) cosmetics and toiletries; 5) textiles; 6) space industry, computer industry; 7) etc. Using this European Standard, it is possible to determin

34、e the bactericidal or fungicidal or yeasticidal activity of the undiluted product. As three concentrations are tested, in the active to non active range, dilution of the product is required and, therefore, the product forms a homogeneous stable preparation in hard water. EN 14885 specifies in detail

35、 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 on bacteria and/or fungi in the conditions in which they are used. NOTE 2 This method cannot be used to

36、evaluate 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.

The surface is transferred to a previously validated neutralization medium so that the action of the disinfectant is immediately neutralized. The number of surviving organisms which
