WEEE stands for waste electrical and electronic equipment and EEE is electrical and electronic equipment (EEE).
EEE is defined in the regulations as ‘equipment which is dependent on electric currents or electromagnetic fields in order to work properly and equipment for the generation, transfer and measurement of such currents and fields falling under the categories set out in Schedule 1 [to the Regulations] and designed for use with a voltage rating not exceeding 1,000 volts for alternating current and 1,500 volts for direct current’.
In other words, if it needs electricity to work, whether it be plugged-in or battery-operated, and is below the voltage limitations, it is EEE.
There are, however, a range of exemptions and anyone in any doubt about whether a product is in Scope should refer to the Agency Guidance document.
