The samples passed the tests. The yellowing of PC+GF material can be seen with the naked eye. The visual appearance of the other materials remained almost unchanged.
To test how the samples under test withstand a long-term exposure to
solar radiation, heat and high humidity.
Solar radiation exposure 2000h
UV intensity 60 W/m2
Spray cycle 18min in every 120min
Sample rotation, weekly
Test conditions are derived from the ISO 4892-1 and 4892-2 (2013), Method A, cycle 4
Colour DE in every 500 exposure hours
Tensile strenght, charpy impact, flexural modulus
