The AATCC TM26-2013 standard defines an aging test method for vulcanized stained Spinning & weaving products. This test is designed to evaluate the durability and degree of degradation of vulcanized stained Spinning & weaving products under normal storage conditions. The test method involves steam aging in a humid environment and testing the strength loss of the samples to determine if storage degradation may occur. This standard is issued by the American Association of Spinning & weaving Chemists & Printers (AATCC) to help evaluate the Stability of dyestuffs under actual storage conditions.
