RoHS, short for Restriction of Hazardous Substances Directive, was first introduced to the legislation of the European Union in 2003 as Directive 2002/95/EC (RoHS 1) and took effect in 2006.
All member states of the EU are obliged to create an individual approach to enforce the compliance of electrical and electronic equipment with the regulation that restricts the use of hazardous substances, for example, lead and mercury.
The substances DEHP, BBP, DBP, and DIBP were added as part of DIRECTIVE (EU) 2015/863 which was published on 31 March 2015.
