Weather testing of polymers is the controlled polymer degradation and polymer coating degradation under lab or natural conditions.
Just like erosion of rocks, natural phenomena can cause degradation in polymer systems. The elements of most concern to polymers are Ultraviolet radiation, moisture and humidity, high temperatures and temperature fluctuations. Polymers are used in every day life, so it is important for scientists and polymer producers to understand durability and expected lifespan of polymer products. Paint, a common polymer coating, is used to change the colour, change the reflectance (gloss), as well as forming a protective coating. The structure of paint consists of pigments in a matrix of resin. A typical example is painted steel roofing and walling products, which are constantly exposed to harmful weathering conditions.

Famous quotes containing the words weather and/or testing:
“Is it possible
That any may find
Within one heart so diverse mind,
To change or turn as weather and wind?
Is it possible?”
—Sir Thomas Wyatt (1503?–1542)
