AATCC 26-2020描述了一种程序，用于确定硫染色纺织材料在正常储存条件下是否会变质，并确定此类变质程度。试样在受控条件下在潮湿大气中进行蒸汽老化，然后进行强度损失测试，以确定是否可能发生贮存变质。

AATCC 26-2020 describes a procedure for determining whether sulfur-dyed textile materials will or will not deteriorate under normal storage conditions and to establish the degree of such deterioration.Specimens are steam-aged in a moist atmosphere under controlled conditions and then tested for loss in strength to determine if storage deterioration is likely.
