Introduction
GB/T 35684-2017 Technical Standard Overview
GB/T 35684-2017 Technical Requirements for Explosion Suppression Materials for Fuel Containers with Explosive Atmospheres is an important technical standard formulated by China for explosive environments of fuel containers. It aims to prevent explosions through explosion suppression materials (explosion suppression material). The standard covers the grade classification, type classification, physical performance requirements and test methods of materials.
Standard Framework Comparison Table
| Chapter Number | Description | Key Requirements |
|---|---|---|
| 1 | Scope | Applicable to the production, inspection and acceptance of explosion suppression materials for explosive environments of fuel containers. |
| 3 | Terms and Definitions | Key terms such as explosion suppression material, mesh, and replacement rate are clarified. |
| 5 | Requirements | Includes specific indicators of material, structural dimensions, physical properties, and characteristic values (see Table 1). |
Technical Requirements and Test Methods
The grades of explosion suppression materials are divided into untreated (grade 1) and lattice conversion coating treatment (grade 2), and the types are divided into Type I, Type II, and Type III according to the geometric structure dimensions. The physical properties and characteristic values of the materials must meet the requirements of Table 1:
Table 1 Physical properties and characteristic values| Performance | Type I requirements | Type II requirements | Type III requirements |
|---|---|---|---|
| Density range (kg/m³) | 24~27 | 24~32 | 37~43 |
| Number of mesh holes (100cm²) | 190±22 | 150±19 | 140±10 |
Implementation suggestions
To ensure the effectiveness of barrier explosion suppression materials, it is recommended in actual applications:
- Select the appropriate material grade and type in strict accordance with standard requirements.
- Perform regular inspections to ensure that the physical properties of the materials meet the requirements.
- Perform adequate pretreatment and testing before installation to avoid environmental factors affecting material performance.
