三种测定方法;通过模拟材料的摄入来测定重金属和其他元素的含量,通过气相色谱法(使用“顶空”法)来测定乙烯基氯,以及通过改进的WKI法来测定甲醛释放量。交叉引用:EN 71-3:1995EN 717-3ISO 6401EN 235EN ISO 3696ISO 3696ISO 187
Three methods to determine; the content of heavy metals and other elements by simulating the ingestion of the materials, vinyl chlorine by GC using the 'head-space' method and formaldehyde release using a modified WKI method.Cross References:EN 71-3:1995EN 717-3ISO 6401EN 235EN ISO 3696ISO 3696ISO 187
