For this purpose, LNE Laboratory is eager to guide you in determining the services you'll need to satisfy such requirements. The application of safety standards makes it possible to evaluate the effectiveness of the device's means of protection. In the context of CE marking, the conformity of products with harmonised standards makes it possible to obtain a presumption of conformity with the requirements of the directives and regulations relating to these standards. To assess compliance with these standards, LNE offers testing and documentary analysis services.

Radio frequency tests are essential to ensure the conformity of equipment using radio frequencies. In particular, its transmission power, spectral occupancy, presence of parasitic emissions,, and reception sensitivity must be checked. However, for the vast majority of products, radio functionality is provided by integrating a module that has already been assessed under the RED directive. In this case, the EMC and electrical safety sections of the final product must be assessed in their entirety.

Typically, an evaluation plan is drawn up, including identification of the various influencing factors, evaluation criteria definition, and test scenarios. Using task-appropriate metrics, the overall product performance is assessed, and underperforming scenarios can be identified. It is also necessary to have various data from the product, which must be qualified and annotated in order to evaluate the product as accurately as possible. This facility is based on MATICS software and high-performance computing resources.

This modular platform covers several fields of robotics. In particular, it features a climate chamber to validate the robot's operation at different temperatures and tracking cameras to measure its movements. The modules designed for movement tests (rough terrain, mazes, etc.) and manipulation tests (handles, valves, 6D positioning) are based on NIST (National Institute of Standards and Technology) standards.

Evaluation on this bench consists of placing a device at the heart of a simulation projected onto a 300° screen while a motion capture system and an instrumented conveyor belt measure its movements, if any. These data are integrated into the simulator in real time so that the device's digital twin follows the same movements and the projected environment is updated accordingly. The simulator also incorporates a physics engine and advanced sensor models, enabling a virtual sensor output to be substituted for the robot's sensors in real time.

The bench offers a realistic representation of a physical environment. This includes high-quality graphics with adjustable precision details for textures, lighting, and shadows, as well as advanced physical models to simulate realistic interactions between objects (collision, thermography). The various environments cover a wide range of scenarios to test AI systems in varied and unpredictable situations. The platform also enables new scenarios to be created to meet specific customer requirements.

This is a setup for testing the transverse spray uniformity of liquid using nozzles mounted on a spray boom. It serves to verify the correct operation of the nozzles and examines the degree of proper liquid spraying on the surface. The degree of uniformity of spraying and quality of the nozzles are determined by the coefficient of spray irregularity.​ Parameters: Table width: 3000 mm; collection groove width: 50 mm​.

The stand is used for verification of the correct operation of algorithms controlling the spectrum of sprayed working liquid in agricultural and orchard sprayers as a function of pressure and temperature. It is used for measuring the size of particles sprayed in the air​. - recording rapid process changes in real time​.

A test stand with dimensions of 30000x8000 mm, with a centrally mounted, hydraulically lifted platform. The stand is used both in accredited tests based on standardised methods or in-house procedures and in non-accredited activities, including research and development work related to the design and testing of autonomous machinery. The stand is used, among other things, for measuring technical parameters, weights, pressure forces, and stability of machinery and equipment.
