Simulation of mechanical, climatic and EMC environment stresses

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.

More information

Main standards used

For mechanical and climatic tests:
GAM EG 13, MIL 810, STANAG 2895 and 4370, EUROCAE ED-14 C / RTCA DO-160D, ISTA, IEC series 60068-2
For EMC tests:
GAM EG 13, MIL 461, RTCA DO-160, NF EN 60601-1-2, IEC series 61000-4-X, 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.
