PRLog - April 4, 2014 - Knowing the process through which substances are being selected for inclusion on “The List” can prove important when trying to choose the right type of product chemistry in the product development phase.
EU defines Methodology Manual to identify and add RoHS hazardous substances.
Furthermore, it can also help manufacturers to better communicate to customers the efforts they undertake to ensure the safety and sustainability of their Electrical & Electronic Equipment (EEE). Here’s a glimpse at how the substance selection process works.
Recital 10 (or preliminary statement 10) of the EU Directive 2011/65/EU (RoHS 2) identifies the use of several substances as a priority for a first substance review process. It also requires the completion of the review by 22 July 2014.
Furthermore, the substances in question need to be reviewed periodically thereafter by the European Commission, either of its own initiative or following the request of a Member State. These substances are:
- Hexabromocyclododecane (HBCDD) a brominated flame retardant
- Bis (2-ethylhexyl)
- Butyl benzyl phthalate (BPP) a commonly used plasticizer
- Dibutyl phthalate (DBP) a commonly used plasticizer
Methodology Manual for Substances Identification and Assessment
A Methodology Manual (http://www.umweltbundesamt.at/
The Methodology Manual underlines the relationship between RoHS and REACH and quotes Recital 16 of RoHS that indicates that information generated by REACH should be used when implementing regulations that cover Electrical & Electronic products. For more details on the RoHS – REACH relation read the SGS Safeguards bulletin No 009/14(http://newsletter.sgs.com/
The Methodology Manual is divided in three major sections:
Part I – Identification of Substances
Covers the identification of substances used in EEE, which may have negative impacts on human health, the environment or the efficient management of WEEE (Waste Electrical and Electronic Equipment).
Part II – Pres-Assessment of Substances
Covering the prioritization of substances used in EEE, which may most likely have negative impacts on human health, the environment or the efficient management of WEEE.
Part III – Detailed Assessment of Substances
Covers the in-depth analysis of high priority substances that may lead to their restriction under RoHS 2.
Methodology Manual for Identification of Priority Substances
The application of the Methodology Manual has already resulted in the identification of various substances and their relevant level of priority. In addition to the four first priority substances mentioned above, additional substances have been identified and could be added to the list of restricted substances in the future. The complete 2nd Interim Report (http://www.umweltbundesamt.at/
Priority I Substances
Eleven substances have been identified as fulfilling all 3 waste criteria and the hazard properties (human health & environment)
- Bis (2-ethylhexyl)
- Butyl benzyl phthalate (BBP)
- Dibutyl phthalate (DBP)
- Diisobutylphtalate (DIBP)
- SCCP (short chained chlorinated paraffins), C10-13
Other halogenated compounds:
- Hexachlorobenzene (already listed in the Stockholm Convention
Priority II Substances
There are four substances that currently fulfill all 3 waste criteria and the hazard properties (human health & environment)
- 1Diethyl phthalate (DEP)
- MCCP (medium chained chlorinated paraffins), C14 – C17 Antimontrioxid
- Tetrabromobisphenol A”
Priority III Substances
Only one substance has been included in this priority category. That substance is: Polyvinylchloride.
Priority IV Substances
Five substances have been identified as belonging to the overall priority category IV:
- Nickel sulfate
- Nickel bis(sulfamidate);
- Beryllium metal
- Beryllium oxide (BeO)
- Indium phosphide
First Set of Public Consultations for Substances Evaluation
A first set of public consultations (http://www.umweltbundesamt.at/
The results will be published in a final report on the methodology developed for identification and assessment of substances.
The final conclusion of the identification and assessment process, and the draft recommendations for inclusion of substances in the RoHS2 list of restricted substances will be presented soon.
Knowledge of Restricted Substances under RoHS2 Is Key
Being on top of the list of substances currently restricted under RoHS 2 or those that are being evaluated for restriction is essential. It is also equally important to understand the process used to identify and prioritize substances for RoHS. This allows manufacturers and suppliers to proactively move towards an alternative substance assessment for their EEE and components.
