CERTIFICATE OUTDOOR LIGHTFASTNESS
SQS 2
SQSUV INK
Result
Good – slight colour changes after 3 years
Testing Parameters
The lightfastness was tested according to ISO 16474-2 (paints and varnishes – methods of exposure to laboratory light sources – part 2: Xenon-arc lamps). The test was performed in a Xenotest 440 by Atlas Material Testing Solutions, using the following parameters:
Energy 60 W/m²Chamber temperature 38 °CBlack standard temperature 65 °CRelative humidity 50 %
The light irradiated by the Xenotest 440 equals 10 times the force of natural outdoor light of an average Central European day. The testing periods of 40, 80 and 120 days is equivalent to one, two and three years of outdoor irradiation.
