In the climatic chambers, the most various environmental factors can be reproduced or simulated in order to verify how materials and products react after periods of prolonged exposure.
Temperature and relative humidity are the most common factors among the various types of climate tests but sometimes they are not enough. Some tests require the solar simulation test.
How Solar Simulation works
As is known, only a small part of light is visible to the human eye, called the visible spectrum.
To simulate solar radiation it is therefore necessary to reproduce the entire spectrum of radiation, which is composed of infrared, visible spectrum, and ultraviolet.
The laboratory climatic chambers are therefore equipped with particular lighting systems which can not only reproduce the whole spectrum of solar radiation, but also selectively certain types of wavelengths and frequencies, to better verify how the sample reacts to the exposure.
Controlling the temperature and relative humidity parameters is also essential to more faithfully simulate the real conditions to which the material or product will be exposed.
What is the Solar Simulation test for?
Prolonged exposure to sunlight has an effect on almost all materials.
But there are products for which the effects of solar radiation are more critical than in others and these are the sectors covered by the solar simulation test in the laboratory.
Particularly affected by the solar simulation test are all those production sectors that implement electronic components that could be damaged by prolonged exposure to solar radiation, i.e. the automotive, military and aerospace sectors. Finally, the photovoltaic panels themselves - whether they are ground-based or used on satellites in the aerospace sector - obviously have to pass the solar simulation test in the laboratory.
Most of these tests are performed on the machine already assembled and therefore require very large climatic chambers, called walk-ins.
The international standard that establishes the characteristics of the solar simulation test is IEC 60904-9:2020.
The automotive sector has a specific standard which lists the recommended procedures: DIN 75220.
Finally, the test on photovoltaic panels is regulated by ASTM E927-19.
The FDM Climatic Chamber for Solar Simulation Testing
FDM climatic chambers can be equipped with different types of lighting designed to reproduce the various types of solar radiation and perform the solar simulation test as outlined by international standards.
In addition, we can build custom chambers to meet each customer's needs and meet the requirements of those tests that require the walk-in chamber.
