Textile test methods — Weather resistance — Xenon arc radiation

This method provides a procedure for the exposure of textile materials of all kinds, including coated fabrics and products made thereof, in an artificial weathering apparatus using a xenon arc lamp and controlled conditions of test. This method includes procedures for both controlled wetting and no wetting of the specimen.

The resistance to weathering of any property of the fabric may be determined by testing the exposed fabric in accordance with the appropriate test method.

If the degree of change in a property due to weathering is required, fabric must be tested both before and after exposure in the weathering apparatus.

The method provides the option of four specific weathering cycles with combinations of light, dark and light, and spray.  Other cycles may be used if agreed upon by parties concerned.
