标准范围

本国际标准描述了两种测定聚合物中游离甲醛（HCHO）的方法分散。使用丙烯酸、丙烯腈-丁二烯、羧基苯乙烯-丁二烯对程序进行了评估醋酸乙烯聚合物分散体。这两种试验方法也适用于聚合物分散体其他组成部分。方法A是游离甲醛含量高于的聚合物分散体的首选方法。如果必须测定较低的甲醛含量或必须进行仲裁分析，建议使用方法B开展。这两种方法都能最大限度地减少因物理或化学性质变化而引起的游离甲醛浓度变化聚合物分散体的化学性质。以所述方式使用时，这些方法没有已知的限制。

This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymerdispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadieneand vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersionsof other compositions.Method A is the preferred method for polymer dispersions with a free-formaldehyde content higher than.Method B is recommended if lower formaldehyde contents have to be determined or arbitration analyses have to becarried out.Both methods minimize changes in free-formaldehyde concentration that can result from changes in the physical orchemical properties of polymer dispersions.There are no known limitations to these methods when used in the manner described.
