EN 513 Plastics - Poly(vinyl chloride) (PVC) Based Profiles - Determination of Resistance to Artificial Weather Conditions

This standard specifies a method for exposing samples made of poly(vinyl chloride) (PVC)-based profiles to xenon arc radiation to evaluate changes in properties.

It can be applied to PVC-based profiles, including foil-coated, lacquered or coextruded ones.

Samples taken from the surface of a profile and practically exposed to weathering are exposed to xenon-arc radiation at the specified radiation, black and white standard temperatures, relative humidity, and sputtering cycle. Changes in the properties of the samples after exposure are determined.

The number of test samples will be as specified in the relevant standard. The test specimens shall be taken from the profile surface exposed to UV radiation so that the longitudinal directions of the test specimens and the profile are the same. Store unexposed reference test specimens in the dark.

Conditioning prior to exposure to laboratory radiation sources is not required unless otherwise noted.
