Introduction
Analysis of the core content of the standard
Scope of application
This standard applies to compressed gas springs that use nitrogen or other inert gases as energy storage media, and specifies the full life cycle management specifications such as term definitions, marking methods, and technical requirements.
Key technical requirements
| Performance indicators | Technical requirements | Test methods |
|---|---|---|
| Force characteristics | Nominal force deviation±5%, dynamic friction≤15N | Dynamic/static test (400mm/min) |
| Cycle life | Force attenuation≤13% after 25,000 times at room temperature | Continuous test of 4-6 times/min |
| Corrosion resistance | No corrosion defects in 96h salt spray test | GB/T 10125 standard method |
Typical application case
The automobile tailgate support system adopts YQ 10/22-200-500 F650 gas spring. After environmental cycle life test:
- Force attenuation ≤5% after 1,000 cycles at -40℃/80℃
- Total attenuation ≤13% after subsequent 18,000 cycles at room temperature
- Oil carryover <0.5g
Implementation suggestions
Design stage
Preferably use the piston rod diameter (GB/T 2348) and stroke series (GB/T 2349), D/d≥1.1 to ensure structural stability.
Production Control
Key Points:
- Coating thickness ≥10μm (QC/T 625)
- Extension speed controlled at 50-350mm/s
- Liquid damping section length determined by negotiation
