Introduction
GB/T 2946-2018 Standard Overview
GB/T 2946-2018 "Ammonium Chloride and Oxide" national standard specifies the product classification, requirements, test methods, inspection rules and labeling, packaging, transportation and storage of ammonium chloride for industrial and agricultural use. This standard replaces the previous GB/T 2946-2008. The main technical changes include the addition of heavy metal limit requirements and adjustments to some indicators.
Product Classification and Technical Requirements
| Category | Main Indicators | Comparison of Old and New Standards |
|---|---|---|
| Industrial Ammonium Chloride | Content, moisture, ignition residue, etc. | Added heavy metal limit requirements (arsenic, cadmium, lead, chromium, mercury) |
| Agricultural Ammonium Chloride | Nitrogen content, particle size, crushing resistance, etc. | Adjusted some indicators and added heavy metal requirements |
Test Methods and Testing Standards
Nitrogen content determination: Use the formaldehyde method or the titration method after distillation. Calculated in terms of ammonium oxide, the result must meet the content range required by the standard.
Moisture determination: Use the Karl-Fischer method or the drying method. The moisture index is of great significance in production inspection and quality spot checks.
Implementation suggestions
Enterprises should strictly carry out production and quality inspections in accordance with the standard requirements, paying special attention to the newly added heavy metal limit indicators. Suggestions:
- Establish a complete quality management system
- Equipped with advanced testing equipment
- Regularly train employees to ensure compliance with the latest standards
