Foreword

Instead of the standard YS/T 94-1996 "copper sulfate (smelting by-products)." Compared with YS/T 94-1996, major changes in this standard as follows. --- Three grades of copper sulfate remains the same chemical composition made appropriate adjustments, the lower limit of the content of copper sulfate was adjusted to 96% water Upper solution was adjusted to 0.1%, adjusted to the lower limit of 0.005%, an increase of As, Pb, Fe, Ni, Co, Zn, Cd, Sb, Bi, oil and chlorinated Regulations and other impurities elements. --- Acidity from the free acid content is adjusted to a pH value represents; --- Modify the contents of the test rule; --- Modify the packaging, labeling, transportation, and other content; --- Increasing the normative references, quality certificate. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard by the Jinchuan Group Ltd. is responsible for drafting.
