American European bending tester
Test Purpose:
To determine if metal wires in children's products bend or break under stress, creating sharp edges or points that pose choking or injury hazards.
Compliance Standards:
- 16 CFR CPS USA: Child Product Safety Certification
- ASTM F963: Standard Consumer Safety Specification for Toy Products
- EN 71: European Toy Safety Directive
Test Methodology:
| Test Parameter | Specification |
|---|---|
| Deformation Test | Apply 3N axial force for 5 minutes |
| Bend Test | Flex the wire at 90° angle with 5mm radius mandrel |
| Edge Evaluation | Check for sharp edges using ISO 4671-1:2017 gauge |
Product advantages:
Ensures Child Safety: Directly tests for potential hazards from metal wires, significantly reducing the risk of cuts, punctures, or ingestion of broken pieces.
Dual Market Compliance: Designed to perform tests required by both US (ASTM, 16 CFR) and European (EN 71) standards, simplifying testing for manufacturers targeting both markets.
Objective and Quantifiable Results: Provides measurable outcomes (deformation percentage, breakage force) and a pass/fail assessment for sharp edges based on standardized methods.
Supports Design and Quality Control: Valuable for validating material choices, evaluating product design, and performing quality checks during manufacturing.
Reduces Risk of Recalls: Helps prevent costly and damaging product recalls by ensuring compliance with safety regulations before products are shipped.
Acceptance Criteria:
- No permanent deformation exceeding 15% of original length
- No sharp edges exceeding 0.5mm radius
- Maximum allowable breakage force ≥ 2N
