RoHS Testing

RoHS specifies maximum levels for the following six restricted materials:

  • Cadmium (Cd): 100 ppm
  • Mercury (Hg): 100 ppm
  • Lead (Pb): 1000 ppm
  • Polybrominated Biphenyls (PBB): 1000 ppm
  • Polybrominated Diphenyl Ethers (PBDE): 1000 ppm
  • Hexavalent Chromium (CrVI): 1000 ppm

RoHS compliance testing can be carried out using portable RoHS analyzers known as x-ray fluorescence or XRF metal analyzers, such from Niton and Innov-X Systems.

Non Destructive RoHS screening (RFA Method)

The screening provides indications as to whether and where hazardous substances may exist in the product according to RoHS. It is especially suited, for instance, to gaining a quick overview in goods receipt check or preliminaryinspections.

Using our custom tailored portable XRF spectrometer, inspection personnel from our company can simultaneously screen for all five restricted RoHS elements and chlorine (Cl) in a matter of few seconds. Using a Portable XRF, is a non-destructive, in-situ point-and-shoot screening method for PVC, PE, alloys, metals, solders, ceramics and packaging materials.

Chemical Analysis by ICP (Verification Method)

RoHS testing is carried out using an initial screening test by XRF, then if high levels of restricted substances are found, further tests may be carried out using ICP, and wet chemistry. The Chemical Analysis department, provides all clients with accurate, precise results that report the total levels of RoHS elements and compounds and their product fully meet RoHS requirements.
