Question & Answer
The article presents a question by a reader and its answer by an expert, on the issue of high voltage diodes being exempted from the Restriction of Hazardous Substances directive in Great Britain. The reader wants to know whether lead (Pb) in electric ceramic parts in microwave ovens is exempt from the directive. Pb is likely to be exempt if the diode is chemically combined with other elements to make a ceramic material. Every other use of Pb in a diode is not exempted.
