    • Lead (Pb)
    • Mercury (Hg)
    • Cadmium (Cd)
    • Hexavalent Chromium (Cr(VI))
    • PBB (Polybrominated Biphenyls)
    • PBDE (Polybrominated Diphenyl Ethers)
  • Halogen free testing
  • Migration metals according to EN71-3 for toy safety
  • EU banned phthalates
  • REACH SVHC 16 banned substances
  • 16 Banned PAHs



As electronic components get smaller, the need for cleaner parts becomes ever more critical. Our cleanliness and micro-contaminant testing service can help to improve your components’ reliability.
