EN 1303 Cylinders for locks
Classification for cylinder durability, key differing, corrosion, temperature and — importantly for retrofit — attack resistance.
What it actually decides
- Attack resistance class, which is what a TS007 or Sold Secure rating sits on top of
- Key differing and key control
- Durability grade
Applies to these lock types
Euro profile cylinder in a mortise case (DIN) · UK oval cylinder (uPVC and composite doors) · Multipoint locking system (uPVC / composite)
Why a retrofit designer cares
An integrated-cylinder smart lock must state its EN 1303 classification, otherwise the buyer cannot compare it with the cylinder it replaces.
