This European Standard is concerned with the special technical safety requirements for liquid pumps and pump units operating with agrifoodstuffs. It augments EN 809 and contains a list of the additional significant hazards which can arise from the pump and pump units used with substances intended for human and domestic animal consumption. In drafting this standard it was assumed that the pumps falling within its scope will conform to all relevant requirement of EN 809. It also establishes requirements and/or measures which lead to a reduction of the risks. This standard is not intended to be used for pumps and pump units at any stage in the public water supply, nor for pumps handling pharmaceutical products, nor for any other application for which more appropriate standards can exist.
