Mercury (Hg) - max 0.1%

The RoHS 2 directive limits mercury in electrical and electronic equipment to a maximum of 0.1 percent by weight on a homogeneous material basis, meaning the substance cannot exceed that concentration in any individual component. This restriction is intended to reduce the environmental and health risks posed by mercury when products are manufactured, used, or discarded. Compliance requires manufacturers to verify that mercury levels stay below the specified limit.
