DIN EN 45501:2016-03

This document (EN 45501:2015) has been prepared by Technical Committee CEN/CENELEC/TC "Non-automatic Weighing Instruments", the secretariat of which is held by BSI. This document is a revision of OIML Recommendation 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. This document specifies the metrological and technical requirements for non-automatic weighing instruments. It is intended to provide standardized requirements and testing procedures to evaluate the metrological and technical characteristics in a uniform and traceable way. In preparing this document, EN 45501:1992 which formed the basis of this standard, was considered, but with additions and amendments to take into account the developments in technology which have occurred in the intervening years. Significant changes include, extensions to the EMC immunity requirements to reflect the greater use of wireless technology for many purposes, enhanced specifications for the integrity and security of software and testing regimes to confirm compliance, requirements for portable and mobile instruments, and recognition of the use of modular elements in families of instruments with enhanced testing requirements for both analog and digital modules and systems for confirming the compatibility of modules when combined into a single instrument or system. Working Committee NA 152-05-01 AA of Technical Section "Wägetechnik" ("Weighing technology") at DIN Standards Committee Technical Fundamentals (NATG) is responsible for this document.
