RoHS (EU Restriction list)

This article has been translated with machine translation.

In October 2022, the RoHS restriction list was launched to iChemistry.

Electrical and electronic equipment may contain hazardous substances that pose risks to health and the environment. The so-called RoHS directive aims to replace and limit hazardous substances in electronics. 

RoHS stands for Restriction of Hazardous Substances in Electrical and Electronic Equipment. Intersolia's RoHS list contains substances that are prohibited or subject to restrictions according to the directive. The list can be helpful for users of chemicals who manufacture electronic equipment or are suppliers of chemical products or components that later in the supply chain are used/end up in electronic equipment. 

The limit values for what is allowed for each of the restricted substances is 0.1% by weight in homogeneous material, except for cadmium which has a lower limit value; 0.01% by weight in homogeneous material. The restriction list in iChemistry is indicative, which means that it does not take into account concentration values and you can choose to manually exclude products from the list if the substance is lower than the approved limit value.

The substances that are regulated are listed in Annex II of the RoHS Directive:

Restricted substances referred to in Article 4(1) and maximum concentration values tolerated by weight in homogeneous materials 

  • Lead (0,1 %) 
  • Mercury (0,1 %) 
  • Cadmium (0,01 %) 
  • Hexavalent chromium (0,1 %) 
  • Polybrominated biphenyls (PBB) (0,1 %) 
  • Polybrominated diphenyl ethers (PBDE) (0,1 %) 
  • Bis(2-ethylhexyl) phthalate (DEHP) (0,1 %) 
  • Butyl benzyl phthalate (BBP) (0,1 %) 
  • Dibutyl phthalate (DBP) (0,1 %) 
  • Diisobutyl phthalate (DIBP) (0,1 %)
