Introduction
GB/T 33064-2016 Standard Overview
This standard specifies the sampling, method principle, test method, result presentation, etc. of the general test method for the determination of chloride (Cl-) in fluoroolefins for refrigerants by turbidity, and is applicable to the determination of chloride in fluoroolefins for refrigerants.
Background of Standard Formulation
With the development of environmental protection and green chemistry, the refrigerant industry has increasingly stringent quality requirements for fluoroolefins. The formulation of GB/T 33064-2016 aims to provide a unified technical specification for the determination of chloride in fluoroolefins to ensure that product quality meets national standards.
Technology Evolution Analysis
Based on the principle of classical chemical reactions and combined with modern experimental technology, this standard proposes a highly sensitive and easy-to-operate detection method. The silver chloride precipitation is observed by turbidity to achieve rapid judgment of chloride.
| Standard Dimensions | GB/T 33064-2016 | Comparison Standards |
|---|---|---|
| Detection Method | Turbidimetric Method | - |
| Equipment Requirements | Measuring Cylinder, Colorimetric Tube, Electronic Balance, etc. | General Laboratory Equipment |
