INTRODUCTION The widespread use of electrotechnical products has drawn increased attention to their impact on the environment. In many countries all over the world this has resulted in the adaptation of regulations affecting wastes, substances and energy use of electrotechnical products. The use of certain substance like lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI) and their compounds, and two types of brominated flame retardants (polybrominated biphenyls, PBB, polybrominated diphenyl ethers, PBDE, (except decabrominated diphenyl ether, DecaBDE) in electrotechnical products is regulated in current and proposed regional legislation. Industry is convinced of the importance of defining testing protocols for regulated substances of electrotechnical products that enter or are made available on markets, where legislation regulating the substance content of electrotechnical product is enacted. Testing may be performed for a variety of reasons including: • As a supplement to supply chain material declarations, companies may choose to test products directly to determine compliance • Companies may require their suppliers to perform testing as a supplement to the supplier’s material declaration • Companies may perform “spot checks” of their suppliers to confirm compliance • Government officials may test as basis to assess compliance
