Your challenges

You need to take appropriate measurements in order to:

• match the specificity of your product or process,
• ensure the traceability of your measurements,
• meet the requirements inherent in your quality and accreditation approaches.

Whatever your problem:

• Innovate by remaining competitive: Companies need to innovate at the lowest cost and on the fastest timeline possible. To accompany these goals, LNE evaluates their measurement methods and uncertainties, from the R&D stage through to the production chain.
• Master new technologies: New technologies are complex and require controls and measurements at all stages of the process: for example, additive manufacturing and the necessity of replicating such manufacturing processes, nanotechnologies, information processing techniques, smart grids,
• Pursue development in respecting the environment: In order to meet the challenges related to climate disruption and resource scarcity, companies and public authorities are rolling out ambitious and innovative action plans: high-performance cost-saving lighting, energy-efficient buildings, mapping of energy loss sources, etc. LNE offers an effective means of support in the search for energy savings. The role of metrology is critical in the area of environmental protection: monitoring of drinking water and indoor or outdoor air quality, verification of machine quality, assistance in designing products with predetermined life cycles.
• Protect human health: Our platforms dedicated to nanomaterial measurements, especially in food supply, and nanoparticulates present in air serve as valuable allies during risk identification steps. Metrology plays an increasingly important role in prevention efforts thanks to work conducted on the traceability of analytical results delivered by analysis laboratories, as well as on the early detection of certain diseases (Alzheimer's, cardiovascular diseases).

Our assets

The LNE organization is:

• assigned to develop and maintain the set of national standards,
• tasked with ensuring the traceability of SI measurements,
• endowed with competences recognized by COFRAC, as evidenced by its multiple accreditations.

Laboratory and on-site calibration

As an essential complement to companies' quality approach, calibration steps enable them to ensure their products meet customers' expectations, guaranteeing output qualit while controlling manufacturing processes and y. Benefiting from a wide range of competences, LNE is renowned as a reference player in this field.

Our calibration laboratories, located in Paris, Nîmes and Poitiers, are accredited by COFRAC and offer the most extensive set of services in addressing mechanical, thermal, optical, chemical and electrical magnitudes.

We are regularly called upon to participate in inter-laboratory comparisons at the international level (i.e. Key Comparisons organized by CIPM), as well as at the European level organized by Euramet and EA, which helps gain international recognition for our calibration certificates.
