WG 2 - Applied metrology for NAWI
This standard provides definitions of quantities of metrological specifications of electronic non-automatic weighing instruments (eNAWIs) used by manufacturers and provides measurement and calculation procedures to obtain values for these quantities. It gives user guidance to define and apply tolerance limits for specifications that are relevant to ensure fitness for the intended use of eNAWIs. Further guidance is given on appropriate risk-based qualification activities (calibration, routine tests, adjustment,…) and on proper use of eNAWIs in order to continuously maintain fitness for the intended use over the complete lifetime of an instrument.

The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Technical Committee (TC) in CEN is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
