Introduction
1. Background and significance of standard formulation
GB/T 32159-2015 "Coking pure pyridine" is an important industry standard formulated on the basis of sufficient research and experiments. This standard stipulates the technical requirements, test methods, inspection rules and other contents of coking pure pyridine, providing a scientific basis for the evaluation and control of product quality.
2. Comparison of standard frameworks
| Dimensions | GB/T 32159-2015 | Reference standards | Comparative analysis |
|---|---|---|---|
| Technical requirements | Pyridine content not less than 99.0%, density range 0.980~0.984 g/cm³ | No specific provisions | The standard clarifies product quality indicators for the first time, making it more operational. |
| Test methods | Gas chromatography, density meter, Karl Fischer method, etc. | Experience judgment method | Introducing modern analytical technology to improve detection accuracy. |
| Inspection rules | If the whole batch fails, double sampling will be conducted for re-inspection | No unified standard | Establish a strict quality control process. |
3. Implementation suggestions
Case analysis:A coking enterprise adopted this standard to control product quality. By establishing a complete testing system and optimizing the production process, the one-time qualified rate of product quality reached more than 98%. Practice has proved that strict implementation of this standard can significantly enhance the market competitiveness of products.
