RoHS Testing ReportLPD Lab Services offer an extended RoHS screening testing service. The RoHS compliance European Regulations limit the amount of certain chemicals in the constituents of products, appliances and subcomponents, the limits apply to the following:

  • Lead (Pb)
  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent Chromium (Cr 6+)
  • Polybrominated Biphenyls (PBBs)
  • Polybrominated Diphenyl Ethers (PBDEs)

In order to declare a product RoHS compliant the lab tests for the presence of certain elements and the levels of some of the above chemical species in the homogenous components of a product. Importantly the lab can perform a RoHS initial screen test in order to check if there are likely to be any significant levels of the named substances if required.

A combination of XRF, FTIR, SEM/EDX and occasionally AAS are used in order to ascertain if the product is RoHS compliant.

PBBs and PBDEs are used as fire retardants in a many product types from polymers and films through to circuit boards and papers. The lab uses XRF calibrated for organic matrices to generally test for the level of bromine in a sample of material: If the level is high then further tests are conducted to ascertain if the bromine is in the PBB or PBDE form using FTIR or other techniques.

Chromium Six Cr(VI) is used in certain products, it is a potent carcinogen and hence is restricted by RoHS regulations. It can occur in paints, inks, coatings, plating, dyes, wood preservers, leather tanning solutions conversion coatings and steels.

SEM/EDX is used to check that lead free solders have been used in various soldered joints in PCBs.

Once LPD Lab Services have analysed your product a test report is issued which meets the requirements of the RoHS standard to ensure you have proof your products are compliant.
