Conformity and market access marks
Marks a manufacturer applies to declare that a product may lawfully be placed on a particular market. Their authority is legal rather than technical, and it is scoped by territory: CE covers the European Economic Area and UKCA covers Great Britain rather than the whole United Kingdom, because Northern Ireland continues to follow the EU regime. Both are routinely read as safety certifications awarded by an authority. Neither is: for most product categories the manufacturer applies the mark on its own assessment and no body grants it.
CE marking
The letters CE in a defined geometric form, declaring conformity in the EEA.
UKCA marking
The letters UKCA declaring conformity for the Great Britain market.
Class II double insulation symbol
A small square inside a larger square — IEC 60417-5172, marking equipment protected by double or reinforced insulation rather than an earth connection.
WEEE symbol
A crossed-out wheeled bin symbol required on electrical and electronic products under EU law, instructing separate collection rather than general disposal.
