1 Scope

This document specifies the color of plastic after exposure to solar radiation, natural climate or laboratory radiation sources that simulate solar radiation after glass filtration

And other appearance performance, mechanics or other performance changes measurement methods. The method of analyzing the data depends on the performance evaluation test of the exposed material

Whether the test is destructive or non-destructive. The exposure test is carried out under the specified conditions of specific exposure standards.
