DIN Standards Committee Health Technologies

Overview

This European Standard specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectant products which are intended to be used for treatment in aqueous systems against Legionella pneumophila that form a homogeneous, physically stable preparation when diluted with buffered ferrous hard water or hard water. Whenever Legionella pneumophila poses a risk to human health, this method is suitable for water used in cooling towers and water for general purposes, like spas, pools, showers and other uses. The method is not suitable for electro-chemical disinfection. This European Standard applies to products used to treat water in order to kill Legionella pneumophila. The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used. This method corresponds to a phase 2, step 1 test. This method does not take into account the fact that Legionella pneumophila is often found in cells of amoebae and/or biofilms and that thereby a product's activity against the bacteria may be reduced. At DIN the Committee responsible for this standard is NA 063-04-07 AA "Chemische Desinfektionsmittel und Antiseptika in der Humanmedizin" ("Chemical disinfectants and antiseptics in human medicine").
