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.

Copper sulfate
(Smelting by-products)
1 Scope
This standard specifies the requirements for copper sulfate, testing methods, inspection rules, packaging, labeling, transportation, storage and quality certificate.
This standard applies to the use of copper electrolysis process crystalline copper sulfate solution containing copper and other raw materials to produce copper. Mainly used for electroplating copper,
Brass plating, copper plating, animal feed additives, and other fields.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
