Other tests for water absorbency, repellency and resistance are standards developed by A-A-T-C-C. AATCC’s focus for standard test method development is on fabric attributes related to fabric wet-processing and finishing. AATCC does not develop performance specifications for categories of textile end products. ASTM does develop test methods and performance specifications for textile and apparel products. One such test is ASTM D47-72, a water flow test that measures the absorbency of terry fabrics used in towels.
