Introduction

1. Background and significance of standard formulation

With the frequent contact of infants and children with textiles, the safety of lead release has received increasing attention. The GB/T 43821-2024 standard aims to standardize the determination method of lead release in textiles and accessories to ensure that the products meet the national mandatory safety requirements.

2. Comparison of standard frameworks

Standard dimensions GB/T 43821—2024 International reference standards
Scope of application Textiles and accessories, including buttons, zippers, etc. EU EN 1240-1:2018 (Toy Safety)
Test methods ICP-OES, GFAAS, ICP-MS AAS, XRF
Limit requirements ≤0.020 μg/(cm²·h) ≤90 mg/kg (toy material)

3. Implementation suggestions and precautions

  • Instrument selection:Based on laboratory conditions, ICP-MS is preferred for higher sensitivity.
  • Sample treatment:Ensure that non-test surfaces are completely covered with wax or paint to avoid interference with results.
  • Data recording:Record the measured values of blank solution and sample solution in detail, and calculate the precision (≤20%).
