标准摘要
[中文适用范围]： 本国际标准规定了一种通过气相色谱法测定基于不饱和聚酯（UP）树脂的增强塑料（聚合状态）中残留苯乙烯单体含量的方法。残留苯乙烯单体含量是评价 UP 树脂在聚合状态下固化程度的重要指标。该方法也可用于同时测定 UP 树脂中的其他挥发性芳香烃。该方法不适用于具有高耐化学性的 UP 树脂。 [外文原描述]： ISO 4901:2011 specifies a method for the determination, by gas chromatography, of the residual styrene monomer in reinforced plastics based on unsaturated polyester (UP) resins in the polymerized state. The residual styrene monomer content is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. The method can also be used for the simultaneous determination of other volatile aromatic hydrocarbons in UP resins. The method is not applicable to UP resins of high chemical resistance.
