This document, AATCC Test Method 192-2009, details procedures for determining the weather resistance of various textile materials, including fibers, yarns, fabrics, and coated fabrics, whether natural, colored, finished, or unfinished. It outlines a method using sunshine-arc lamp exposure, offering two options: with wetting (Option A) and without wetting (Option B), to simulate environmental conditions. The test evaluates material degradation through metrics like color change, breaking strength, tearing strength, and bursting strength, comparing exposed specimens to unexposed originals and agreed-upon comparison standards. The standard emphasizes that it does not inherently imply an accelerated test for specific applications, requiring contractual parties to determine the correlation between test results and actual in-use exposure. It includes detailed sections on principles, terminology, safety, apparatus, specimen preparation, procedure, evaluation, and precision.
