IP rating



The L2EC has over 50 environmental chambers that generate low and high temperature stress.

It is not always easy to ensure that your materials are free of functional and mechanical defects related to the extreme environmental stresses.

To generate stresses with low and high temperatures, rapid temperature changes and moist heat, the L2EC has more than 50 environmental chambers that can produce the following range of conditions:

Usable volume

From 17dm³ to 12 m³


From -80°C to 450°C

Rapid temperature variation

Up to 15°C/minute

Relative humidity

From 10 to 98% RH

Thermal shock

From -80°C to 200°C

L’ensemble des moyens est supervisé, de plus, une possibilité d’assurer un monitoring des produits lors des essais afin de déceler et de positionner dans le temps d’éventuelles défaillances.

Salt spray

In addition to standard stresses, some equipment must be subjected to corrosive environments

Some equipment must be subjected to corrosive environments, which is often done using salt spray tests.

We can generate salt spray continuously or cyclically, with or without drying and moisture saturation phases, based on the required benchmarks in the certification phase.

Our laboratory has five test beds to meet your needs and requirements, with volumes ranging from 450 dm³ to 2 m³ for testing.
We directly meet manufacturers’ special requirements according to the main standards in the field.

Vibrations and mechanicals

To provide comprehensive services to industrial clients, the L2EC laboratory offers testing in mechanical environments.

Providing a comprehensive response to industrial clients is one of the L2EC Laboratory’s main missions.

During the validation or certification phases in environments, we offer testing in mechanical environments.

The L2EC Laboratory specialises in vibrations and carries out mechanical vibration testing in line with the main benchmark standards using two shaker units that can move vertically and horizontally.

There are three types of vibration testing:

  • Endurance testing: Random and Sine
  • Dynamic characterisation: Sine
  • Mechanical shocks: vibration pulses

Our vibration test methods cover frequencies of 2,000 Hz, with forces that can reach 50,000 N.

The L2EC laboratory can also perform the HAST method in accordance with the JEDEC 22 standards, ranging from 85°C to 130°C in moisture. The L2EC also offers component mechanical endurance testing as well as tensile tests to mechanically characterise products before and after endurance testing.

IP rating

The L2EC can perform many degrees of IP ratings according to EN standards and NF EN IK standards to classify the degree of protection of products.

The L2EC laboratory can perform many degrees of EN 60529, ISO 20653 and DIN 40-050 ingress (IP*) and NF EN 60068-2-75 and NF EN 62262 impact (IK*) standards. The degrees correspond to the classifications of products subjected to extreme stresses from solid and liquid agents and mechanical impact.

The laboratory has a 1-m3 dust chamber for testing in accordance with EN-60529 (talcum powder) and ISO 20653 (Arizona test dust) standards.

*IP: Degrees of protection provided by enclosures.

*IK: Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts.

What you need to know

We fully support all your classification requirements concerning liquid ingress.

Additional tests

The laboratory can suggest changes and adaptations to environmental test beds to create customised tests.

Since its creation, the L2EC laboratory has been guiding its clients in meeting their challenges.

It designs and develops test beds for customised tests to perform, among others, the following stresses:

  • Small motions (can be combined with temperature)
  • Tension/compression tests and mechanical cycling through manual and automated stresses (can be combined with temperature)
  • Clipping and unclipping
  • Click ratio
  • Insertion and extraction
  • Alternating bending and tension
  • Screwing and unscrewing
  • Locking and unlocking

    What you need to know

    The laboratory can also suggest changes and adaptations to environmental test beds to create customised tests.
