Heat, cold, humidity, rapid temperature variation,... accelerate the climatic ageing of your products and check their resistance and good functioning.
From 32 litres for the smallest enclosure to 93 m3 for the largest, from -90 °C to +600 °C, with speeds of up to 20 °C/mn, the Group's various laboratories have more than 70 climatic enclosures to carry out climate ageing tests and/or test their endurance and good performance.
These means are complemented by our salt spray, thermal shock, UV resistance and IP code (water and dust protection code).
Climatic enclosures are associated with mechanical and hydraulic means allowing to carry out combined tests of vibrations, temperatures, mechanical stresses, endurance, circulation of fluids, pressure variation...
Within the framework of qualification, the climatic part of the test program allows to discover several failure modes related to extreme temperatures and/or their variation: mechanical deformation of parts, modification of the characteristics of electronic components, modification of properties of liquids (e. g. lubricants) and solids (material cracking, hardening,...). In the case of wet heat testing, the moisture stresses in addition to those in temperature allow to verify the impact of oxidation or corrosion phenomena, the swelling of certain materials, the delamination of composite materials, or even changes in thermal and electrical insulation characteristics...
This test allows equipment to be subjected to icing conditions resulting from rapid temperature variations, relative humidity and altitude. Here again, it is a question of discovering failure modes linked to extreme conditions.
Our climatic chambers (dry heat, humid heat, warmth, cold, humidity, icing, freezing, rain, rapid temperature variation,...)
- Number: 70
- Useful volume up to 93 m3
- Temperature: - 90 °C to + 650 °C
- Rapid temperature change: 20 °C/min
- Relative humidity: from 10 to 100% Hr
Note: We provide you with a hot (+135 °C), cold (-60 °C) and humidity climatic chamber, equipped with exhaust gas extraction for tests on large dimensions, or even a complete vehicle.
The importance of monitoring and available servitudes
For the duration of the tests, from a few minutes to several months, the equipment under test can be continuously monitored: thermocouple, voltage, current, rotation speed, micro-power cuts,...
Our multiple servitudes (electric, hydraulic, pneumatic) and our skills in the vibratory, climatic and hydraulic fields allow us to carry out tests in the configurations of representative environments in normal or severe use.
