Overview

Legal metrology

Legal metrology covers all the regulations applied by the national or European authorities to guarantee the quality of measuring instruments used in:

  • commercial transactions (eg. weight-price scales for retail stores, petrol pumps, water meters, etc.)
  • operations concerning public health or safety (eg. gas analysers, tachographs, radar speed detectors, Breathalysers, etc.).

These instruments are inspected and validated at several stages:

  • design (EC type examination, national type examination, design approval, verification of installation)
  • manufacture (initial verification)
  • use (control of instruments in service).

LNE's activities

  • conformity assessment of non-automatic weighing instruments (NAWI), in accordance with Directive 2009/23/EC modified (EC type examination, unit EC verification, approval of manufacturers' quality management systems).

 

National level:
In accordance with French law (Décret of 3 May 2001), LNE is designated by the French Ministry of Industry to:
