EN 1634-1 Fire resistance and smoke control tests for door and shutter assemblies
How a complete doorset — leaf, frame, hardware, seals — is fire tested. The lock is tested as part of the assembly, not alone.
What it actually decides
- Whether a given lock is allowed on a fire-rated doorset
- The fire rating of the assembly (30, 60, 90, 120 minutes)
- That changing hardware changes the tested configuration
Applies to these lock types
Euro profile cylinder in a mortise case (DIN) · Multipoint locking system (uPVC / composite) · Singapore HDB main-door mortise set and metal gate lock
Why a retrofit designer cares
The number one way a well-intentioned smart lock retrofit becomes a liability: it fits perfectly and invalidates the door's certificate.
