Production of CHARPY V certified reference specimens (MRC)

The Charpy test offers a mechanical means for determining the resistance of a specimen to shocks or the notching effect. The resilience test consists of breaking notched bars on an impact strength tester and then measuring the resulting breaking energy. To ensure the precision of their equipment, industry owners must verify their raw materials with certified impact bending machines using Charpy reference specimens designed by LNE.

Characterization of 3D printer accuracy

Calibrating your measurement instruments enables connecting them to the international system of units, while ensuring the traceability of your measurement results. This approach serves to satisfy the requirements of your quality assurance protocol. We propose providing you with a determination of the metrological performance of your 3D printer based on a designed part model.

Technical assistance in evaluating measurement uncertainty

Performing the right measurement leads to making the right decision! Measurement uncertainty serves to indicate the quality of a measurement result. In order to fully utilize the results of tests, calibration or the corresponding data, it is necessary to understand and master all relevant associated uncertainties.

Metrology-based training

Our training curricula and modules have been designed with the aim of providing you the skills and tools necessary to effectively carry out your daily operations and practices.

Regulatory verification of evidential breath analysers (EBA)

As manufacturers of evidential breath analysers (EBA) or as users of this type of equipment for alcohol measurements in the breath, you must ensure that they are reliable and comply with the regulations in force. To meet these requirements, LNE carries out initial and periodic verifications and tests under COFRAC accreditation.

Ethanol/Water solution

In order to be placed on the market, evidential breath analyzers and breath alcohol test devices must comply with normative and regulatory requirements. Reference materials enable you to calibrate and check your bench, and to control and validate your production. LNE offers two ranges of reference materials of Ethanol/Water solutions, a certified range and a standard range.

Service of controlling dimensional readings and geometric tolerances

Calibrating your measurement instruments provides visibility with respect to the International System of units and moreover ensures the traceability of all your measurements. This approach satisfies the requirements of your quality system. Our three-dimensional and optical measurement instruments make it possible to control and calibrate all kinds of parts, be they standard or custom.

Electrical calibration in the presence of High Voltage

For equipment suppliers, energy producers, industries or laboratories regularly working with voltages capable of reaching values of 300 kV, the LNE Laboratory offers a wide range of services aimed at characterizing your facilities and/or installations.
