Introduction
Key points of the core upgrade of the standard
| New items | 2006 version | 2024 version | Technical significance |
|---|---|---|---|
| Head mold types | 2 types | 5 types | Adapt to different head circumference sizes |
| Test items | 11 items | 17 items | New extreme environment tests such as resistance to molten metal |
| Pretreatment conditions | 3 types | 5 types | Added extremely high temperature (150℃) pretreatment |
Analysis of key test methods
1. Impact absorption performance test
Using 1#/2# head mold, a 5kg weight is free-falling from a height of 1m, and the peak force is required to be ≤4.9kN. The test device includes:
- Concrete base (≥500kg)
- Dynamic force sensor (range 20kN)
- Hemispherical impact head (radius 48mm)
2. Puncture resistance test
Using a 3kg puncture cone (cone angle 60°), falling from a height of 1m. Critical control points:
Technology evolution analysis
The main changes in the standard are reflected in:
- Test dimension expansion: New practical performance indicators such as wearing stability and dynamic strength
- Environmental adaptability improvement: Add extreme conditions tests such as extremely high temperature (150℃) and molten metal (1400℃)
- Accuracy upgrade: Force measurement accuracy reaches ±3%, displacement resolution 1μm
Implementation suggestions
| Links | Operation points | Common problems |
|---|---|---|
| Sample pretreatment | Strict temperature control (±2℃), test within 30s after leaving the environment | UV aging box temperature exceeds 60℃ |
| Headform selection | Select 1# (≤85mm) or 2# headform according to wearing height | Impact test headform is not verified regularly |
| Data recording | Acceleration peak value retains 1 decimal place, action time is accurate to 0.01ms | Pretreatment environment parameters are not recorded |
