Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics used in the veterinary area - Test method and requirements (phase 2, step 1); German version EN 1657:2016
Chemische Desinfektionsmittel und Antiseptika - Quantitativer Suspensionsversuch zur Bestimmung der fungiziden oder levuroziden Wirkung chemischer Desinfektionsmittel und Antiseptika für den Veterinärbereich - Prüfverfahren und Anforderungen (Phase 2, Stufe 1); Deutsche Fassung EN 1657:2016
Overview
DIN EN 1657 specifies a test method and the minimum 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 % or less, as some dilution is always produced by adding the test organisms and interfering substance. This laboratory test takes into account practical conditions of application of the product, including contact time, temperature, test organisms and interfering substances, in other words 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 test corresponds to defined experimental conditions. However, for some applications the recommendations of use of a product may differ and therefore additional test conditions need to be used. This European Standard applies to products that are used in the veterinary area, that is 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 tests to one another and to "use recommendations". The European Standard has been prepared by CEN/TC 216 "Chemical disinfectants and antiseptics", the secretariat of which is held by AFNOR (France). DIN Standards Committee NA 057-02-03 AA "Desinfektionsmittel Tierhaltung/Lebensmittelbereich (Spiegelgremium für CEN/TC 216/WG 2)" ("Disinfectants for veterinary use and food area (national mirror committee of CEN/TC 216/WG 2)") is responsible for this standard.
