Standard Specification for Helmets for Non-Motorized Wheeled Vehicles Used by Infants and Toddlers
1Key Takeaways
1.1 This specification covers performance requirements for helmets manufactured for use by infants and toddlers as passengers or operators of nonmotorized vehicles intended for their use. This specification recognizes the desirability of lightweight construction and ventilation; however, it is a performance standard an…
2Expert Interpretation
This expertly explains the ASTM F1898-22 standard for helmets for infants and toddlers in non-motorized wheeled vehicles, covering performance requirements, test methods, and compliance labeling. It analyzes key technical indicators such as head fit and impact testing, and provides advice on helmet selection and standard implementation.
Analysis of the core requirements of the standard
ASTM F1898-22 standard proposes the following key requirements for infant helmets (suitable for children aged 12-24 months):
| Test Items | Technical Parameters | Test Conditions |
|---|---|---|
| Impact Test | ≤300gPeak Acceleration | Flat Anvil 6.2m/s, Hemisphere/Kerbstone Anvil 4.8m/s |
| Fixation System | Elongation≤30mm | 4kg Drop Test from 0.6m |
| Field of view | ≥105° horizontal field of view | Refer to F1446 test method |
Key technology evolution
Main revisions of the 2022 edition:
- Head shape center of gravity tolerance adjusted from ±5mm to -6.5~40mm (X-axis)
- Explicitly prohibit partial declaration of conformity (Article 1.3)
- New Curb anvil test requirements (Article 9.1)
Test implementation points
Sample requirements
Four test samples are required for each model/size, and the following tests are conducted separately:
- Normal temperature test (ambient temperature 23±2℃)
- Low temperature test (-20±2℃)
- High temperature test (50±2℃)
- Humidity test (immersion in water for 4 hours)
Compliance implementation recommendations
Manufacturers need to pay special attention to:
- The permanent label must contain the warning "For infants and young children only"
- The head shape selection must match the three standard sizes of A/C/E
- The impact test point must be located above the test line (see Figure 1)
