    Overview of RoHS Testing

    The RoHS Directive (2011/65/EU, amended by 2015/863/EU) regulates the use of hazardous substances in Electrical and Electronic Equipment (EEE), including components and raw materials. RoHS testing verifies that 10 hazardous substances in homogeneous materials (materials that cannot be mechanically separated) are below specified limits, protecting human health and the environment. Compliance requires technical documentation, a Declaration of Conformity (DoC), and, where applicable, the CE mark for EU market entry.

    The ten substances tested under RoHS are:

    1. Lead (Pb)

    2. Cadmium (Cd)

    3. Mercury (Hg)

    4. Hexavalent Chromium (Cr VI)

    5. Polybrominated Biphenyls (PBBs)
