  • Lead or lead compounds
Pb <1000 ppm <0.1%
  • PolyBrominated DiphenylEthers
PBDEs <1000 ppm <0.1%
  • PolyBrominated Biphenyls
PBBs <1000 ppm <0.1%
  • Bis(2-ethylhexyl) phthalate
DEHPO <1000 ppm <0.1%
  • Benzyl butyl phthalate
BBP <1000 ppm <0.1%
  • Dibutyl phthalate
DBP <1000 ppm <0.1%
  • Diisobutyl phthalate
DIBP <1000 ppm <0.1%


These thresholds apply to any homogenous materials or component that cannot be mechanically disjointed such as wires, plastics, solders, or alloys.
