AATCC 169-2020规定了使用受控试验条件在人工风化仪中暴露各种纺织材料的程序，包括涂层织物及其制品。本试验方法包括控制湿润和不湿润试样的程序。当在标准纺织品测试条件下进行评估时，耐降解性可通过材料的强度损失百分比或残余强度百分比（断裂、撕裂或爆裂）和/或色牢度来测量。

AATCC 169-2020 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.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.
