1)Humid conditions are defined in terms of service class 2 of ENV 1995-1-1 which is characterized by a moisture content inthe material corresponding to a temperature of 20 °C and the relative humidity of the surrounding air only exceeding 85 %for a few weeks per year. Boards of this type are suitable for use in biological hazard classes 1 and 2 of EN 335-3.SIST EN 312:2004
