This European Standard specifies requirements covering the design, construction, installation and operation of aerosol separators to be used in ventilation systems, including technical safety, ergonomic and hygienic features. This European Standard is applicable to ventilation systems in commercial kitchens, associated areas and other installations processing foodstuffs intended for commercial use. Kitchens and associated areas are special rooms in which meals are prepared, where tableware and equipment is washed, cleaned and where food is stored. This European Standard is not applicable to ventilation systems that are to be used in domestic kitchens. A method of verification of each requirement is also specified. Unless otherwise specified, the requirements of this standard shall be checked by way of inspection and/or measurement. NOTE Please note the possible existence of additional or alternative national regulations on installation, appliance requirements and inspection, maintenance and operation.
