标准摘要
[中文适用范围]： 本文件规定了两种测定聚合物分散液中游离甲醛（\(\mathrm{HCHO}\)）的方法。本文件适用于丙烯酸、丙烯腈丁二烯、羧基苯乙烯-丁二烯和乙酸乙烯酯聚合物分散液。其他成分的聚合物分散液也适用。方法A（UV/Vis分光光度计法）适用于游离甲醛含量高于 \(10 \mathrm{mg} / \mathrm{kg}\) 的聚合物分散液。方法B（HPLC法）用于测定较低甲醛含量或进行仲裁分析。 [外文原描述]： This document specifies two methods for the determination of free formaldehyde (HCHO) in polymer dispersions. This document is applicable to acrylic, acrylonitrile butadiene, carboxylated styrene-butadiene and vinyl acetate polymer dispersions. It is also applicable to polymer dispersions of other compositions. Method A (UV/Vis spectrometer method) is applicable to polymer dispersions with a free-formaldehyde content higher than 10 mg/kg. Method B (HPLC method) is applicable for determining lower formaldehyde contents or carrying out arbitration analyses.
