The Conformitè Europëenne (CE) Mark is a standardised marking on products to demonstrate that they comply with European standards related to safety, health and environmental requirements.

Products that conform with European standards can display the CE marking.

The CE Mark is a stylised CE letter which is shown below: 

The mark should be visible on the product - such as a window or door - to demonstrate that the appropriate standards have been met by the manufacturer.  The minimum size of the mark on any product is 5mm.

The standards are rigourously enforced, and any products which do not meet the relevant standards for safety cannot display the CE Mark.
