Objectives
Note
These tests may be supplemented by acoustics tests and electrical safety tests
- Climatic tests
- are performed to assess the resistance, long-term behaviour and ageing effects of a product in a range of simulated conditions, including high or low temperature, humidity, salt spray, low pressure and permeability. IP protection index P (in french - pdf - 199 kB)
- Mechanical tests
- are performed to assess the behaviour of a product in real conditions of use by applying mechanical stresses (impact, vibration, acceleration, etc.).
- Electromagnetic compatibility (EMC) tests
- are performed to verify the capacity of a device or system to operate satisfactorily in its electromagnetic environment without causing electromagnetic interference.
Regulations and standards
Note
LNE performs conformity tests according to the European Directives on Electromagnetic Compatibility (2004/108/EC), Low Voltage (2006/95/EC), etc.

LNE resources
LNE has an extensive range of sophisticated test resources at its centres in Trappes and Nîmes.
For climatic tests:
- climatic chambers
- thermal chambers
- salt spray tanks
- heat-cold-vacuum chamber
- IP permeability test equipment
For mechanical tests:
- hydraulic vibration tables
- shakers (including one which combines vibration with climatic conditions)
- vertical impact tables
- accelerated vertical impact machines
- horizontal impact machines
- release machines
- traction-compression machines
For EMC tests:
- EMC chamber
- immunity benches
LNE can also adapt these resources to specific test conditions.
