本标准规定了涤纶短纤维（含中空纤维）和涤纶长丝阻燃性能试验方法 氧指数法。
本标准适用于涤纶短纤维（含中空纤维）和涤纶长丝阻燃性能 氧指数的测定。
本标准仅用于测定在实验室条件下材料的燃烧性能，控制产品质量，而不能作为评定实际使用条件下着火危险性的依据，或只能作分析某特殊用途材料发生火灾时所有因素之一。本标准不适用于评定受热后呈高收缩率的材料。

Scope

This standard specifies the oxygen index method for testing the flame retardant properties of polyester short fibers (including hollow fibers) and polyester filaments. This standard is applicable to the determination of oxygen index of polyester short fibers (including hollow fibers) and polyester filaments. This standard is only used to measure the combustion performance of materials under laboratory conditions and to control product quality. It cannot be used as a basis for assessing the fire risk under actual use conditions, or can only be used to analyze one of all factors when a fire occurs in a special-purpose material. . This standard is not applicable to the evaluation of materials that exhibit a high shrinkage rate after being heated.
