ROHS (Restriction of Hazardous Substances)
(RoHS) is a set of EU regulations that implements EU Directive 2002/95 that restricts the use of hazardous substances in electrical and electronic equipment. This directive bans placing on the EU market, any product having an electrical/electronic component containing more than thresholds set for lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominateddiphenyl ether (PBDE) flame retardants.
On 4 June 2015, the EU commission has published a new Directive (EU) 2015/863 to amend Annex II to EU RoHS 2 (Directive 2011/65/EU) to add the following 4 phthalates onto the list of restricted substances.
- Bis(2-Ethylhexyl) phthalate (DEHP): max 0.1%;
- Benzyl butyl phthalate (BBP): max 0.1%;
- Dibutyl phthalate (DBP): max 0.1%;
- Diisobutyl phthalate (DIBP): max 0.1%.
|Status||Substances and Limits|
It shall be noted that above maximum concentration values apply to each homogeneous material rather than a product or a part itself. A homogeneous material means material of uniform composition throughout that cannot be mechanically separated into different materials.
DEHP, BBP, DBP and DIBP are primarily used as plasticisers to soften plastics. They will be restricted from 22 July 2019 for all electrical and electronic equipment apart from Category 8 (medical devices) and Category 9 (monitoring and control equipment) that will have an additional two years to comply by 22 July 2021.
Some electrical and electronic products are out the scope of EU RoHS 2. Military equipment, large-scale stationary industrial tools, large-scale fixed installations, active implantable medical devices, and photovoltaic panels are excluded from RoHS 2. Batteries and package materials are also out the scope of RoHS since they are subject to different directives.
In addition to that,annexes III and IV of RoHS 2 contain certain applications that are exempt from RoHS restrictions (For example, Cadmium in helium-cadmium lasers). Some RoHS 2 exemptions are time limited.
QT Labs offers complete scope of testing for RoHS 2.0 (Effective 22nd July 2019). For more details, please contact us.
