Restriction of Hazardous Substances (RoHS)
The Restriction of Hazardous Substances (RoHS) Directive comes from the European Union. Its goal is to keep the following six substances out of new electrical and electronic equipment sold in EU countries. Here are some details about the allowable amounts of the substances and why they have been used:
- Lead (Pb), less than 1000 parts per million: Used mostly in circuit board soldering
- Mercury (Hg), less than 1000 parts per million: Used in electronic switches (older technology not used by Rodgers for many years)
- Cadmium (Cd), less than 100 parts per million: Used in electronic components/assemblies
- Hexavalent chromium (chromium xxx or Cr6+), less than 1000 parts per million: A material used in toe pistons
- Polybrominated biphenyls (PBB), less than 1000 parts per million: Fire retardants in various electronic components/assemblies
- Polybrominated diphenyl ether (PBDE), les than 1000 parts per million: Fire retardants in various electronic componets/assemblies.
To comply with RoHS requirements, we have received compliance statements from each of our parts suppliers. Rodgers, however, does not solely rely on their claims. For compliance verification, Rodgers purchased X-ray fluorescence equipment - a capital investment of $50,000 - that we use to sample test incoming parts for the presence of restricted substances.
