Scope

This Standard specifies a procedure for exposing paint coatings to artificial
weathering in xenon-arc lamp apparatus, including the action of liquid water
and water vapor. The effects of this weathering are evaluated separately by
comparative determination of selected parameters before, during and after
weathering.

Summary	This standard specifies the paints and varnishes exposed to xenon lamp fixtures and water vapor under artificial weathering test procedures. By comparing the results of aging coating before aging, the aging process, and after aging selected parameters assessed individually. This standard describes the most important parameters of the exposure apparatus described in detail the conditions of use.
