Many products require CE marking before they can be sold in the EU. CE marking indicates that a product has been assessed by the manufacturer and deemed to meet EU safety, health and environmental protection requirements. It is required for products manufactured anywhere in the world that are then marketed in the EU. CE marking is only obligatory for products for which EU specifications exist and require the affixing of CE marking.
The CE marking must be visible, legible and indelible.
The CE marking must consist of the initials "CE", both letters should have the same vertical dimension and be no smaller than 5mm (unless specified differently in the relevant product requirements).
If the CE marking cannot be affixed to the product itself, you can affix it to the packaging if there is any, or to any accompanying documents.
Some Allegion products have the CE marking. For example, certain Von Duprin exit devices conform with the requirements and have CE marking on the installation instructions.
