- Introduction
Background of Standard Revision and Core Changes
GB/T20096-2021 replaces the 2006 version of the standard. The main technical upgrades are reflected in:
Revision dimensions Requirements of the 2006 version Changes in the 2021 version Technical significance Classification system Weight classification is not clear New A/B classification (20-100kg/20-60kg) Mechanical performance requirements for people of different weights Safety indicators Ground clearance requirements without brakes Single-row 7-17mm/Double-row ≥10mm Optimize braking effectiveness while preventing scratches Harmful substances No limit value for polycyclic aromatic hydrocarbons is specified 16 new PAHs are regulated (Class I ≤10mg/kg) Prevent carcinogenic risks of plastic components
Analysis of key technical requirements
1. Structural safety
Increased energy of vertical impact test: Class A for single-row reaches 135J (unclassified in the 2006 version), corresponding to an impact speed of 4.5m/s, to verify the deformation resistance of the wheel frame.
2. Environmental friendliness of materials
- Formaldehyde content: Direct contact materials ≤75mg/kg (water extraction method)
- Azo dyes: Textiles ≤20mg/kg, leather ≤30mg/kg
- Newly added separate limit for benzo[a]pyrene (≤1mg/kg)
3. Performance test method
The wheel wear rate test uses P80 sandpaper with an inclination angle of 9°. The wear rate of Class A under a load of 40kg in 5 minutes is ≤8%, which is a more relaxed requirement than Class B (≤5%).
Implementation suggestions
Production enterprise response measures
- Update design specifications: Recalibrate product load parameters according to Class A/B
- Supply chain control: Establish a traceability system for hazardous substances (PAHs/formaldehyde)
- Testing equipment configuration: Shaw A-type hardness tester, friction testing machine, etc. are required
Key points of quality verification
Type inspection should focus on:
① Deformation of wheel frame after impact ② Impact resistance of brake ③ Color fastness of lining (≥Grade 3)
