RoHS: What is it and Why is it Significant to Electrical Manufacturers

What is RoHS?

The abbreviation RoHS stands for Restriction of Hazardous Substances. In the beginning, RoHS was put in place, to restrict the use of certain materials in Europe. This was due to their hazardous nature. Therefore, the use of these restricted materials was regulated within electrical devices. Since July 1, 2006, every electrical device in the European Union must pass RoHS mandates.

What does RoHS Mandate?

There are specific materials that RoHS has banned due to them being hazardous.

The main hazardous materials include:

  • Lead (Pb)
  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent Chromium (CrVI)
  • Polybrominated Biphenyls (PBB)
  • Polybrominated Diphenyl Ethers (PBDE)
  • Finally some Phthalates
    • DEHP
    • BBP
    • DIBP

Due to the materials effect on the environment, they have been banned. This banishment is a result of their pollution to the landfills. Also, these materials can be harmful to any workers who work with electronic equipment that contains them.

Product Testing 

When RoHs tests a product for compliance, they use two analyzers. These two analyzers check and confirm that products comply with restrictions. These two analyzers are X-ray fluorescence along with XRF metal analyzers.

Who is Responsible for Compliance?

Originally compliance to the Restriction of Hazardous Substances was in Europe. However, as the United States exports electrical products to European countries, they started to adapt to the same restrictions. Therefore, responsibility for compliance falls on any business who not only sells electronics, it also falls to the companies who assemble electronic products. In addition to the fully assembled devices, components and early assembly of the electronic products are subject to restrictions.
