Guide for Testing Point of Sale (POS) Devices (Non-Automatic Weighing Instruments) - 446Kb 

May 2007, issue 3ENDEFRRS


The European Standard on non-automatic weighing instruments EN45501 contains the requirements for non-automatic weighing instruments subject to legal metrological control in order to provide presumption of conformity to the essential requirements of EC Directive 90/384/EEC. The requirements of that standard apply to all devices performing the relevant functions, even if manufactured as separate units (EN45501 Point 2.4). Therefore, a Point of Sale (POS) device is subject to the relevant requirements of EN45501. This guide, WELMEC 2.2, which follows the principles established in the WELMEC 2.5 "Guide for modular approach", specifies the requirements for a POS device connected to a non-automatic weighing instrument intended to be used for direct sales to the public.
