Statutory quality system approval

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 repair measuring instruments.

How to apply for approval of your quality system

Read our [guidelines] on the approval procedure (pdf - 415 kB) and then complete and send us the [application form] (pdf - 85 kB) and the [application file] (pdf - 73 kB)


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.
