Probably the single most frequently occurring and most misunderstood issue in electronic product safety is electrically-caused fire. I thought I would review fire processes in plastics materials (the most common flammable construction material in electronic products).

Richard Nute examines how transformers behave when subjected to transient overvoltage, both magnetically and capacitively.

The leakage current measuring circuits in IEC 950 and those in North America are exactly the same.

Almost every safety standard has requirements addressing the accessibility of certain parts.

For the purposes of safety, what is “working voltage,” and what is its relevance to the safety of the equipment?

During the 1930s, 1940s, and 1950s, Underwriters Laboratories did basic research in the field...
