In the world, average values and methods to test outdoor<br />
fabrics are developed based on characteristics of 2<br />
regions: Arizona and Florida.<br />
Florida is characterized with high density sunlight, allyear-round<br />
high temperatures, and high levels of annual<br />
precipitation as well as humidity.<br />
Once all these factors combined, they create the harsh<br />
climate which make Florida an ideal place to conduct<br />
weathering test.<br />
WEATHERING BS-EN ISO 105-B04<br />
We can define climate conditions of Florida as “the<br />
worst conditions”.<br />
Arizona:<br />
Arizona has a hot, arid climate with high UV radiation,<br />
which is particularly suitable for the products which are<br />
sensitive to these harsh conditions. As the Arizona test<br />
In addition, maximum air temperatures in Arizona is<br />
15°F higher than those of Florida and temperature to<br />
which Black Panels are exposed is 20°F higher than the<br />
latter.<br />
Arizona also has extreme temperature fluctuations due<br />
to which materials may be subject to size variations due<br />
to the expansion and shrinkage. Unique climate of Arizona<br />
justifies it as being the most ideal region for testing<br />
the color and luster, color constancy, thermal aging and<br />
physical properties, light-fastness and tensile strength<br />
of textile products, in particular. As UV lights generally<br />
travel along shorter wavelengths, they cause products<br />
to degrade relevantly faster.<br />
During tests, sample positioning method and exposure<br />
angle have an important effect on critical test parameters.<br />
In the tests conducted:<br />
• Amount of Solar Energy<br />
• Sample Temperatures<br />
• Humidity and Moistness Duration<br />
are taken into consideration.<br />
Exposure Angle Test samples are normally positioned<br />
so that they will face towards Ecuador to maximize the<br />
Solar light dose. Any object exposed to outdoor will<br />
receive more solar energy than if light hits it from a
