Introduction
GB/T 23846—2017 Standard Overview
Cobalt sulfamate is an important electroplating reagent, widely used in the field of metal surface treatment. GB/T 23846—2017 standard specifies the quality requirements, test methods and safety specifications of Cobalt sulfamate in detail, replacing the old standard GB/T 23846—2009.
Comparative analysis of standard frameworks
| Project dimensions | Requirements of the 2009 version | Revisions of the 2017 version |
|---|---|---|
| Indicator system | Contains requirements for the content of elements such as cobalt and sodium, but does not specify specific indicators for sulfate and density. | Added specific values for sulfate and density, and deleted the nitrate indicator. |
| Test methods | Only the determination steps of some elements are specified. | Added a new test solution preparation process, and supplemented the content calculation formulas for multiple elements such as nickel and copper. |
| Inspection rules | Contains basic quality inspection requirements. | The inspection items are refined, a "safety" chapter is added, and the inspection process is optimized. |
Practical application of standard implementation
Case analysis:Taking the determination of sulfate content in cobalt aminosulfonate as an example, the laboratory needs to prepare grade 3 water according to GB/T 6682 and perform turbidity tests according to the method described in Section 4.13. This method generates barium sulfate precipitation and compares it with the standard solution to ensure that the product quality meets the requirements.
Implementation suggestions
- Sampling and preparation:Strictly follow GB/T6678-2003 for sample collection and prepare the test solution according to the method in the standard appendix.
- Quality Control: It is recommended to calibrate key indicators (such as pH and density) regularly to ensure the accuracy of the measuring equipment.
- Safety Precautions: Operators need to wear protective equipment, pay special attention to avoid direct contact with skin and eyes, and develop a spill response plan.
