As closers for fire/smoke doors have a critical safety function, application of the CE mark requires independent verification by a notified certification body involving initial type-testing of the product to BS EN 1154 and/or BS EN 1155, inspection of the manufacturer’s factory production control and continuing surveillance and approval of the factory production control system.
Recommended for interior or exterior doors including:
• Offices

CE marking is a key indicator of compliance with European Union legislation. All products which fall within the scope of the EU’s New Approach Directives and comply with all essential requirements must carry the CE mark.
