标准摘要
[中文适用范围]： 本国际标准规定了通过测量具有不同孔径尺寸的筛子上保留的量来测定氯乙烯均聚物和共聚物树脂颗粒尺寸分布的方法。 结果可以用单个筛子上保留的量或整个测试样品的平均粒径来表示。 不建议将该方法用于筛孔尺寸小于 0.038 毫米的筛子。 [外文原描述]： ISO 22498:2005 specifies a method for the determination of the size distribution of particles of vinyl chloride homopolymer and copolymer resins by measuring the amounts retained on a selection of sieves having meshes of various aperture sizes. The results can be expressed either in terms of the amount retained on the individual sieves or as the mean particle size for the whole test sample.
