A weighing instrument is a measuring device that determines the mass of a body by using gravity, and can at the same time determine other masses, parameters or mass-related features. A weighing instrument is considered non-automatic if an operator is required to perform weighing operations.
The legislation applicable to measuring instruments is covered by two new-approach directives: the NAWI Directive for non-automatic weighing instruments, and the MID Directive, concerning measuring instruments (counters, conversion devices, taximeters, etc.).
The 2014/31/EU (NAWI) Directive, in force since 6 April 2016, is leading to major changes in the ways of working, in documents and markings of non-automatic weighing instruments. In particular, it defines precise obligations for each position in the distribution chain for the four categories of economic operators involved: manufacturers, importers, authorised representatives and distributors.
To be admitted into operation, these instruments must be manufactured in accordance with the requirements of the NAWI Directive, and labelled with the CE marking and the supplementary metrology marking downstream of the declaration of conformity by a Notified Body.
Conformity assessments under the NAWI Directive include:
RINA is a Notified Body authorised to carry out conformity assessments under the NAWI Directive for to the D/D1 and F/F1 forms. As a Body recognised throughout the European Union, we contribute to promoting the integration of the economic system promoted by the Directive.
The notification is published and available on the NANDO portal (New Approach Notified and Designated Organisations.
