Introduction
1. Background and significance of the standard
GB24754-2009 "Prometryn Technical Material" national standard is one of the important standards in my country's pesticide field, which mainly stipulates the quality requirements, test methods, and labeling and packaging of Prometryn technical materials. This standard was implemented in 2010, replacing the previous HG2201-1991 industry standard, reflecting the important progress in my country's pesticide standardization process.
2. Comparison of standard frameworks
| Dimensions | Old standard (HG2201-1991) | New standard (GB24754-2009) |
|---|---|---|
| Scope of application | Applicable only to promethazine technical | Extended to include impurities generated during production |
| Quality requirements | Limits of some impurities are not specified | New indicators such as loss on drying and sodium chloride are added |
| Test methods | Potentiometric titration is not included | Multiple quantitative analysis methods are added |
| Marking and packaging | No specific requirements | Explicitly implement GB3796 |
3. Interpretation of the core content of the standard
3.1 Improvement of quality requirements
The new version of the standard has higher requirements for the mass fraction of promethazine technical, stipulating that the mass fraction should be ≥96.0%, and has added the limit indicators of impurities such as loss on drying and sodium chloride (≤1.0%). These changes reflect the high attention paid to product purity and stability.
3.2 Optimization of test methods
The standard adopts advanced analytical techniques such as gas chromatography and potentiometric titration to ensure the accuracy and reliability of the test results. In particular, the newly added infrared spectroscopy identification method provides multi-dimensional technical support for product quality control.
3.3 Safety and storage and transportation requirements
The standard emphasizes the safe use specifications of the product, including protective measures such as avoiding human contact and respiratory inhalation, and puts forward clear requirements for storage and transportation conditions, such as moisture-proof, sun-proof and preventing mixing with food.
4. Implementation suggestions
- Enterprise level: Strengthen the construction of quality control system, equip with advanced testing equipment, and ensure that products meet the requirements of the new version of the standard.
- Regulatory authorities: Increase the intensity of standard publicity and implementation, carry out law enforcement inspections, and crack down on illegal activities that do not meet the standards.
- Scientific research institutions: Focus on technical difficulties in the standards and promote the improvement of the industry's technical level.
