Sunlight tests
Validate the resistance of your equipment and materials to solar radiation
Why carry out sunlight tests?
Sunlight tests are used to assess the resistance of materials and equipment exposed to prolonged solar radiation. These tests are essential for :
- Assess the thermal effects of solar radiation on materials (whitening, chalking, cracking, loss of gloss, deformation).
- Simulate heating due to prolonged exposure and its impact on equipment performance.
- Comply with international standards such as MIL-STD-810, STANAG 4370, AECTP 300 and NF EN 60068-2-5.
Sunlight tests
Tests designed to simulate solar radiation are carried out to simulate the deterioration of equipment exposed to prolonged sunlight.
As part of a qualification process, these tests can be carried out under specific climatic conditions (temperature, rain, humidity, frost, etc.) according to cycles (day/night, wet/dry phases, etc.).
Test programmes are based on the equipment's life profile. Tests can simulate the ageing of products located behind glass (shop windows, car interiors) or outdoors (radiation + weather conditions).
What sectors are involved in these trials?
