Introduction
Core changes in the standard revision
| Comparison dimensions | 2012 edition | 2020 edition |
|---|---|---|
| Scope of application | Two-way supervision of import and export | Imported products only (HS842410) |
| Inspection mode | Single inspection method | Dual-track system (conformity verification + sampling inspection) |
| Technical basis | Citing 3 items including GB4351.1-2005 | New requirements of the Environmental Protection Law |
Key points for implementing the inspection mode
The conformity verification mode is applicable to enterprises with good credit, and focuses on checking:
- Consistency between product nameplate and declared materials
- Pressure indicatorGreen area range
- Spray hose length ≥400mm (filling volume＞3kg/L)
Sampling inspection mode requires 11 tests, and the key items include:
- Sealing performance test (Article 6.7)
- Fire extinguishing test (Article 6.6)
- Safety protection device test (Article 7.9)
Corporate compliance implementation suggestions
- Prepare technical documents in advance: including product manuals, type test reports, and original factory test data
- Key self-inspection items:
- Permanent mark integrity (including water pressure test pressure value stamp)
- CO2 fire extinguisher overpressure protection device
- Sampling response strategy: Maintain a 5% spare parts rate to meet re-inspection needs
Technology evolution analysis
This standard reflects three major trends: ① From export orientation to import supervision focus ② Differentiated hierarchical management of inspection models ③ Increase environmental compliance requirements. Compared with international standards such as NFPA10-2018, it is more stringent in the water pressure test indicators of fire extinguisher bottles.
