RoHS
Review Identifies Candidate Substances
RoHS Review: Candidate Substances
Directive 2002/95/EC - RoHS
Regulation EC 1907/2006 - REACH
Article 4(3) and
Article 6 of
the RoHS directive require the periodic review of new scientific
evidence to consider whether other hazardous
substances should be added to the list of prohibited substances.
The required review was prepared by the Oko-Institut e.V., which issued
its final report "Study on Hazardous Substances in Electrical and
Electronic Equipment, Not Regulated by the RoHS Directive" in October
2008.
|
Four criteria were used to identify "high priority
hazardous substances" |
|
|
Substances meeting the criteria for classification as DANGEROUS per
Directive 67/548/EEC |
|
|
Substances meeting the criteria for classification as substances of
very high concern (SVHC) in accordance with REACH |
|
|
Substances which
have been found as CONTAMINANTS in humans and biota |
|
|
Substances which can form hazardous substances
during the collection and TREATMENT of electrical & electronic
equipment |
|
Fourteen substances
were identified as high priority hazardous substances |

1327-53-3 |

|
Five substances
were selected as candidate substances
for inclusion in RoHS |
| |
TBBP-A |
Tetrabromo
bisphenol A |
| |
HBCDD |
Hexabromo-cyclododecane |
| |
DEHP |
Bis (2-ethylhexyl)
phthalate |
| |
BBP |
Butylbenzyl-phthalate |
| |
DBP |
Dibutylphthalate |
| |
Exemptions for
specific applications may be requested except for HBCDD (no
exemptions allowed) |
| |
Recommended
transition period is 24 months except for TBBP-A used as
reactive flame retardant (36 months) |
| |
Caveat: cannot make
"robust recommendation" because documented environmental, economic
and social data for substitute substances are not complete (no
comprehensive risk assessments) |
|
Rationale for not including other
substances as RoHS candidate substances |
| |
MCCPs, SCCPs and
nonylphenol/nonylphenol ethoxylates are used only in small
quantities or by a very limited number of manufacturers. Although
they should be phased out, their inclusion is RoHS is considered to
be a disproportionate response. |
| |
Beryllium and beryllium oxide are
rarely used in consumer electrical and electronic equipment.
Recycling is desirable because beryllium is expensive. To support
recycling, parts should be labeled and easily removable during
dismantling (excludes alloys up to 2% by weight). |
| |
PVC does not meet the criteria for
classification as dangerous in accordance with Directive 67/548/EEC.
The group of organobromine and organochlorine substances needs to be
investigated on a case by case basis. |
