Kemična razkužila in antiseptiki - Kvantitativni suspenzijski preskus za vrednotenje fungicidnega delovanja ali delovanja kemičnih razkužil in antiseptikov na kvasovke v živilski in drugih industrijah, gospodinjstvu in javnih ustanovah - Preskusna metoda in zahteve (faza 2, stopnja 1)

Ta dokument določa preskusno metodo in minimalne zahteve za fungicidno delovanje ali delovanje kemičnih razkužil in antiseptikov na kvasovke, ki tvorijo homogen, fizikalno stabilen pripravek, če so razredčeni s trdo vodo oziroma, pri izdelkih, ki so pripravljeni za uporabo, z vodo. Izdelke je mogoče preskušati samo pri 80-odstotni ali nižji koncentraciji, ker dodajanje preskusnih organizmov in moteče snovi vedno povzroči razredčenje.
Ta dokument se uporablja za izdelke, ki se uporabljajo v živilski in drugih industrijah, gospodinjstvu in javnih ustanovah, izključeni pa so področja in primeri, ko obstajajo zdravstvene indikacije za dezinfekcijo ter izdelki, ki se uporabljajo na živih tkivih, razen tistih, ki se uporabljajo za higieno rok v zgoraj navedenih področjih.

– ribe, morski sadeži in podobno;   – moka, mletje in peka;
– jajca in jajčni izdelki;      – živalska krma;
– živalska krma;                      – itn.

Introduction
This European Standard describes a suspension test for establishing 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 interfering 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 test
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.
1 Scope
This document 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
