To place your products on market and ensure their reliability under real-world conditions, you must demonstrate their ability to withstand the climatic stresses to which they will be exposed throughout their life cycle. LNE carries out climatic tests simulating variations in temperature, humidity or pressure, in order to assess their robustness, performance and compliance with the applicable requirements.
Why carry out climatic testing?
Climatic testing aims to ensure that a product can withstand the environmental stresses to which it will be subjected during transport, storage or use. In particular, it enables the observation of phenomena such as corrosion, oxidation or the degradation of thermal insulation.
By replicating conditions such as extreme temperatures, humidity, thermal cycles or salt spray in the laboratory, these tests validate the robustness, safety, reliability, durability and compliance of products.
They play a key role in qualification programmes by revealing various failure modes, such as mechanical deformation of parts, deterioration of electronic components, or changes in physical properties (cracking, hardening, etc.).
Climatic testing enables manufacturers to:
- identify weaknesses in their products,
- optimise their design,
- anticipate behaviour under real-world or extreme operating conditions,
- demonstrate compliance with regulatory requirements,
- reduce the risk of failure,
- enhance customer satisfaction and confidence.
LNE’s simulation and qualification services for harsh environments
We offer a wide range of characterisation services, including:
- Testing under extreme conditions: cold, heat, humidity, vacuum, overpressure
- Rapid temperature variation tests
- Thermal shock tests
- Altitude tests: pressure and temperature/humidity control
- Sunlight exposure tests
- Salt spray tests
- Ice tests (on drones, aircraft doors, etc.)
These tests can be combined with vibration testing and may be instrumented and monitored continuously.
Functional performance checks can be carried out before and after the environmental tests.
