Children’s Clothing

children-clothingSafety testing of apparel and accessories for children focuses on small parts ingestion and strangulation hazards.

Primary laboratory testing includes:

  • Button,snap, trim, and appliqué attachment resistance
  • Toxicity level testing for lead, cadmium, nickel, and heavy metal content in trim components
  • Safety and dimension evaluation of cords and drawstrings
  • Overall safety assessment of garments with attention to sharp points and sharp edges (zippers and hasps)
  • Flammability resistance of children sleepwear
