1. What is RoHS?
The RoHS term is being used as an indication of the EU regulation 2002/95/EG (see chapter ‘Laws and regulations”). RoHS stands for ‘Restriction of use of certain Hazardous Substances in electrical and electronic devices’, that is restriction of the use of specific hazardous material in electric and electronic devices.Since 1 July 2006, all electr(on)ic devices that are being introduced to the European market have to conform to this regulation. The RoHS regulation is not apllicable to products that were already on the market before this specific date (and are currently in the stock chain). These specific products can be sold. This regulation has been transformed to Dutch legislation: the Decree management electric and electronic devices (see ‘Laws and regulation’).
2. Which materials are liable to prohibition?
Electric and electronic devices may not consist of higher than the regulated concentrations of the following substances:
- Lead (Pb)
- Mercury (Hg)
- Cadmium (Cd)
- Six hydric chromium(Cr(VI))
- Polybrominated biphenyl (PBB) en polybrominated diphenyl ether (PBDE) (used as flame retardant in specific synthetics)
3. What is the regulated maximum concentration?
Maximum concentrations rise to 0.1 weight percent of the homogeneous material, except for cadmium which has a maximum of 0.01 weight percent.
4. What is homogeneous material?
The definition of a homogeneous material is a singular substance that can be (theoretically) separated from other substances (for example a tin layer on lead in a component, casing on a cable, et cetera). The limiting values mentioned in question 3 do not apply to the weight of the finished article, the assembly part or even a component.
5. Does this prohibition apply to all electric and electronic devices?
Please see the answer to question 4 in range document (see ‘Publications’).
6. Where can hazardous materials be found?
| Substance | Possible application |
| Lead (Pb) | Solder Finishing layers Paint (pigment or prepared drier) PVC (stabilizer) |
| Cadmium (Cd) | Pigment Pvc contacts |
| Mercury (Hg) | Fluorescent lamps Sensors Relays |
| Six hydric chromium (CrVI) | Corrosion resistant layers Corrosion resistant paint |
| Polybrominated biphenyl (PBB) polybrominated diphenyl ether (PBDE) | Flame retardant used in specific synthetics |
