AATCC Test Method 169-2009

Weather Resistance of Textiles:  Xenon Lamp Exposure

Developed in 1987 by AATCC Committee RA64

1.  Purpose and Scope

1.1  This test 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 controlled conditions of test.  This test method includes procedures for both controlled wetting and no wetting of the specimen.
1.2  Resistance to the degradation is measured either as percent strength loss or percent residual strength (breaking, tearing, or bursting) and/or colorfastness of the material when evaluated under standard textile testing conditions.

2.  Principle

2.1  Samples of the textile material to be tested and the agreed upon comparison standard are exposed simultaneously to a xenon lamp source under specified conditions.   Resistance of the test material to degradation is compared to that of a comparison standard.
