ISO 17608:2015规定了一种通过测试断裂力保持力来确定裸弹性纤维纱线对氯化水环境（如游泳池）的阻力的方法。 规定了不同的替代试验条件。考虑了三种不同的浓度和两个不同的暴露时间。 ISO 17608:2015仅适用于裸弹性纤维纱线。纱线的结果不能用来预测织物的性能。

ISO 17608:2015 specifies a method to determine the resistance of bare elastane yarns to chlorinated aqueous environments, such as swimming pools, through testing of the breaking force retention. Different alternative test conditions are specified. Three different concentrations and two different exposure hours are considered. ISO 17608:2015 is applicable to bare elastane yarns only. Result achieved from yarns cannot be used to predict the fabric performance.
