Introduction
Interpretation of GB/T 22379-2017, the National Standard of the People's Republic of China
Standard name:Sodium metal for industrial use
Release date:This standard was released in 2017 and replaced GB/T22379-2008.
Background of standard formulation and analysis of technological evolution
With the wide application of industrial sodium metal in the fields of nuclear industry, chemical industry, medicine, etc., the requirements for its quality and safety are increasing. The revision of GB/T22379-2017 mainly targets:
- Added product classification: Class I is for nuclear industry and other industries; Class II is for general industrial use.
- Added Class I index requirements, adjusted the original index to be applicable to Class II, and optimized it.
- Inductively coupled plasma optical emission spectrometry (ICP-OES) was introduced for the determination of iron and potassium contents.
Comparative analysis of standard frameworks
| Items | Old version of the standard (GB/T22379-2008) | New version of the standard (GB/T22379-2017) | ||
|---|---|---|---|---|
| Main indicators | Modified content | New content | Other adjustments | |
| Product classification | Unclear classification | Added Class I and Class II classifications | New test method chapter | |
| Sodium metal content (Na) | No specific requirements | Class I: ≥99.80%, Class II: ≥99.50% | Introduction of arbitration method and inductively coupled plasma optical emission spectrometry (ICP-OES) | |
Implementation suggestions
To ensure the quality and safety of industrial sodium metal, it is recommended that:
- Quality control:Manufacturers should strictly follow the standard requirements for sampling and inspection, especially in the determination of sodium metal content, potassium, calcium, chloride and iron.
- Storage and transportation:Products should be double-packed to ensure moisture and water resistance. Avoid high temperature and vibration during transportation, and keep away from fire and oxidants.
- Safety Measures: Operators should receive special training, wear protective equipment, and strictly abide by safe operating procedures, especially when it comes to the storage and handling of metallic sodium.
