The European Commission’s DG Environment is consulting on the list of substances which are restricted under the recast of the Restriction of Hazardous Substances (RoHS) Directive (RoHS2), used in Electrical and Electronic Equipment (EEE).
The use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) in EEE has been banned/restricted since 2006, although some exemptions are allowed for specific applications where there is no alternative.
The Commission have identified the flame retardants Tetrabromobisphenol A (TBBP-A) and Hexabromocyclododecane (HBCDD) and the phthalates Bis (2-ehtylhexyl) phthalate (DEHP), Butyl benzyl phthalate (BBP), Dibutyl phthalate (DBP) as high priority substances and should be reviewed (with the exception of TBBP-A) in the first tranche of reviews.
The intention is to publish the updated list of restricted substances in 2014.
Measurement of the substances in EEE is not a trivial matter; methods of analysis for Chromium (VI) and brominated flame retardants are still under development to a certain extent and the number of certified reference materials (CRMs) for these is still worringly low. Good quality analytical measurements are an essential part of enforcement of RoHS2.
