Introduction
Analysis of core requirements of the standard
| Technical indicators | Test requirements | Safety threshold |
|---|---|---|
| Penetration resistance | The test blade does not contact the head mold surface | Except the ear holes |
| Shock absorption performance | 8 impact point test | ≤275gPeak acceleration |
| Wearing system | Extensibility test | 25mm maximum displacement |
Key technology evolution
This standard is equivalent to the ISO102562:2016 international standard, and the main technological breakthroughs are reflected in:
- New Helmet Wear Index (HPI) quantitative indicator
- Refine the test matrix of 6 specified impact points + 2 non-specified impact points
- Introduce modular elastomer (MEP) impact test method
Implementation suggestions
Precautions for manufacturers
- The shell material selection should meet the Shaw A60±5 hardness requirement
- The ear hole design must meet the 38mm maximum opening limit
- Permanent marking must include safety warnings
Key points for testing agency operations
- Environmental treatment must cover the temperature range of -20℃~50℃
- The impact test time interval is controlled at 60±30 seconds
- The free fall test device in Appendix A is preferred
Comparative analysis of standards
Compared with the old version of the standard, the main changes in GB/T40926.2-2021 are:
