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.
