BS PD IEC/TR 62697-2:2018规定了总量定量测定的试验方法 未使用和使用过的绝缘液体和固体基质中的腐蚀性硫（TCS） 腐蚀性硫物种转化为金属（铜、银等）硫化物。硫化物 形成的有机物被定量地转化为硫酸盐；硫酸盐通过浊度测定 测量或使用离子色谱法。交叉引用:IEC 62697-1IEC 60422ISO 5725-1DIN 51353 IEC 60296EN 13601ASTM D130CIGRE技术报告378IEC 60475IEC 60050-212IEC 60567IEC 62535:2008ASTM D1275-15购买本文件时可提供的所有当前修改件均包含在购买本文件中。

BS PD IEC/TR 62697-2:2018 specifies a test method for the quantitative determination of total corrosive sulfur (TCS) in unused and used insulating liquids and solid matrices through the conversion of corrosive sulfur species to metal (copper, silver etc.) sulfides. The sulfides formed are quantitatively converted to sulfates; sulfates are determined through turbidity measurement or with ion chromatography.Cross References:IEC 62697-1IEC 60422ISO 5725-1DIN 51353IEC 60296EN 13601ASTM D130CIGRE Technical report 378IEC 60475IEC 60050-212IEC 60567IEC 62535:2008ASTM D1275 - 15All current amendments available at time of purchase are included with the purchase of this document.
