If you wish to market your measuring instruments in France, Europe, and worldwide ? LNE enables you to certify their design in compliance with regulatory requirements. As a manufacturer, repairer, or installer of regulated measuring instruments, you can gain greater flexibility by having your quality management system certified.
Before being placed on the market, measuring instruments subject to legal metrology requirements must undergo a certification procedure to demonstrate their compliance with regulatory requirements, in particular through design validation (type examination). Then, during manufacturing, two options are available : involve a third-party body to assess the conformity of the instruments, or rely on a quality management system previously certified by a notified body such as LNE, thereby enabling the manufacturer to carry out certain control stages themselves.
Certification of a Regulated Measuring Instrument
EU Type Examination Certificate
Type examination consists of validating the design of a measuring instrument based on technical documentation and, where applicable, examinations and tests carried out on one or more specimens of the instrument type.
Type examination results in the issuance of a certificate confirming that the instrument type meets the requirements applicable to its category and, where applicable, defining the specific conditions for verification or use of the instrument.
EU Design Examination Certificate
EU design examination is provided for under Module H1 of Directive 2014/32/EU (MID).
OIML Certificate
OIML certification is a voluntary certification system based on the requirements of OIML Recommendations. Its purpose is to facilitate administrative procedures and reduce the costs associated with international trade in measuring instruments subject to regulatory requirements.
When the type examination of your instrument is carried out in accordance with an OIML Recommendation, obtaining an OIML-CS certificate can facilitate your approval procedures in countries that recognize this type of certificate.
The list of OIML International Recommendations for which LNE can issue OIML certificates is available on the OIML website.

Certification of your Quality Management System for Legal Metrology
CE marking or initial verification of instruments is the control operation confirming that new or repaired instruments comply with the requirements applicable to their category.
Directives 2014/31/EU (NAWI) and 2014/32/EU (MID) provide for CE marking to be affixed directly by the manufacturer when its quality system has received prior approval from LNE. In this case, LNE acts as a notified body for the approval of quality management systems under the various modules involving quality assurance.
French national regulations (Decree No. 2001-387) provide for similar arrangements for manufacturers of regulated measuring instruments not covered by European legislation, as well as for repairers and installers.
New: Evolution of the MID Directive
Published in April 2026, this development aims to strengthen the contribution of measuring instruments to more efficient and transparent use of energy and resources.
More specifically, the amendments to the Directive :
- extend its scope to certain equipment related to the energy transition, such as electric vehicle charging devices,
- modify the requirements applicable to several categories of instruments (electricity, gas, and thermal energy meters) to ensure that they meet current challenges relating to measurement, transparency, and energy consumption management.
LNE supports certified companies in analysing these changes and their impact on their current or future certifications. >> Contact us
