Measuring systems for liquids other than water, gas meters and gas volume conversion devices are now covered by the Measuring Instruments Directive.
> More information
If your measuring instrument is in the process of being developed or you wish to assess/review the conformity of one of your instrument's functions, LNE can perform a pre-diagnosis of conformity covering all or part of the statutory requirements.

Type examination covers validation of the design of a measuring instrument on the basis of information supplied in an application file and - if required - examinations and tests performed on one or more specimens of the instrument type. Following type examination, LNE will issue a certificate stating that the instrument meets the requirements for its category. If applicable, the certificate will specify particular conditions for verification or use of the instrument.
To apply for type examination, you need to send LNE:

CE marking on a new or repaired instrument indicates that it meets the requirements covering its category. Directives 90/384/EEC (NAWI) and 2004/22/EC (MID) specify that CE marking may be affixed by a manufacturer whose quality system has been approved by a Notified Body. LNE is notified to perform quality system approval (for all modules requiring quality assurance).
French regulations (Décret of 3 May 2001) make similar provisions for companies that manufacture, repair or install measuring instruments.
LNE ISO 9001 certification
Companies applying for quality system approval may also apply for ISO 9001 certification of their quality management system. This certification is extremely useful both for SMEs and for large companies whose certification needs concern different parties (buyers, local authorities, subcontractors, etc.). LNE provides a one-stop service optimizing both the time and the cost of the certification process.
