RoHS Compliance Testing

Meeting the Directive’s Requirements

RoHS Compliance Testing has become standard procedure for most manufacturers, sellers, distributors and recyclers of electrical and electronic components or equipment sold or used in the European Union. The need for RoHS testing is a result of the Restriction of Hazardous Substances Directive or RoHS Directive, which became effective on July 1, 2006. The Directive was drawn up in the European Union to protect human health and the environment from hazardous substances by restricting the use of six hazardous chemicals in electrical and electronic products.

Testing Per RoHS Requirements

The Chemistry Lab at Laboratory Testing Inc. near Philadelphia, PA (USA) can determine the level of the first four listed substances restricted by RoHS in component materials. Although we do not test specifically for the last two, we can determine if total Bromine is less than the highest limit for the most Bromine rich compound, thereby determining that the material meets RoHS requirements.

  • Lead (Pb)
  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent Chromium (Cr(VI))
  • Polybrominated Biphenyls (PBB)
  • Polybrominated Diphenyl Ethers (PBDE)

RoHS has set maximum concentration values for each of these restricted substances. All values are set at 0.1%, except for cadmium with a limit of 0.01%. Laboratory Testing helps customers ensure RoHS compliance by performing quick, reliable RoHS testing and analysis of component materials to verify levels of the restricted substances. LTI has the capabilities to RoHS test for lead, mercury, cadmium and hexavalent chromium, and can analyze total bromine.

RoHS compliance testing is performed in our lab using spectroscopy and wet chemistry methods to determine the concentrations of these RoHS substances in test samples. All RoHS testing results are fully documented in Certified Test Reports for our customers’ records.

RoHS Directive Update

RoHS and the recast directive RoHS2 that went into effect in July 2011 do exempt a number of materials and products from the requirements set forth in the Directive and include additional restrictions that went into effect on December 31, 2011. The new RoHS2 Directive is officially titled Directive 2011/65/EU of the European Parliament and of the Council of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment. More information is available at the National Measurement Office website.

Our Customers Say:

“I wanted to write and applaud LTI for assisting us in calibrating some new equipment, while re-calibrating equipment that was moved. We did not have enough advance notice to schedule LTI to come in and complete the calibration / re-calibration of some of our equipment. As a result, LTI did what they could to get us out of a jam and reduce the one to two week turnaround down to two days. I wanted to let LTI know that this was very much appreciated and we value the service your organization gives us.“
