This European Standard has been adapted from the OIML Recommendation R 76-1, Edition 2006, Non-automatic weighing instruments Part 1 – Metrological and technical requirements – Tests by a Joint Working Group from CEN and CENELEC. It was elaborated following a standardization request from the Commission of the European Communities to CEN and CENELEC to establish a European Standards related to Council Directive 2009/23/EC on Non-automatic weighing instruments.
