BS EN 1303 is the European standard on cylinders for locks used for security and protection to keep our belonging and dwelling places safe. 

BS EN 1303 applies to cylinders and their keys for such locks as are normally used in buildings and are designed to be used with cylinders, where the locks have an operational torque of a maximum of 1,2 Nm. 

BS EN 1303 establishes one category of use, three grades of durability, three grades for fire and four grades corrosion resistance all based on performance tests as well as six grades of key-related security based on design requirements and five grades on performance tests that simulate an attack. 

BS EN 1303 includes tests of satisfactory operation at a range of temperatures and specifies test methods to be used on cylinders and their protective measures linked with these cylinders and recommended by the manufacturer. 

The suitability of cylinders for use on fire or smoke-door assemblies is determined by fire performance tests conducted in addition to the performance testing required by BS EN 1303.
