AATCC TM186-2023e, Weather Resistance: UV Light and Moisture Exposure

Developed in 1999 by AATCC Committee RA64 (editorially revised and reaffirmed 2013; Revised 2015, 2022, 2023; editorially revised 2024.

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 a laboratory artificial weathering exposure apparatus employing fluorescent UV lamps as a light source and using condensing humidity and/or water spray for wetting.

2. Principle

2.1 Specimens are exposed to a fluorescent UV light source and to periodic wetting under controlled conditions. Resistance to degradation is rated in terms of a comparison standard and the exposure criteria, percent loss in strength, or percent residual strength (breaking or bursting as appropriate) and/or color change of the material when evaluated under standard textile conditions.
