ISO 17280:2015提供了一种测定由环氧乙烷合成的表面活性剂（如烷基醚硫酸盐和醇乙氧基化物）中1,4-二恶烷残留量的方法。 该方法适用于1,4-二恶烷含量超过5 mg/kg的样品。对于含有超过100 mg/kg的1,4-二恶烷的样品，应将样品溶液稀释至适当浓度。

ISO 17280:2015 provides a method for the determination of 1,4-dioxane residues in surfactants which are synthesized from epoxyethane, such as alkyl ether sulfates and alcohol ethoxylates. The method is applicable for samples containing 1,4-dioxane more than 5 mg/kg. For samples containing 1,4-dioxane more than 100 mg/kg, the sample solutions should be diluted to appropriate concentration.
