DIN EN 1303:2015-08

This European Standard 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 maximum 1,2 Nm. This European Standard specifies performance and other requirements for the strength, security, durability, performance and corrosion resistance of cylinders and their original keys. It 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 attack. This European Standard includes tests of satisfactory operation at a range of temperatures. It specifies test methods to be used on cylinders and their protective measures linked with these cylinders and recommended by the manufacturer. The committee responsible for this standard is NA 005-09-44 AA "Schließzylinder" (SpA zu CEN/TC 33/WG 4/TG 4)" ("Cylinders for locks" (mirror committee of CEN/TC 33/WG 4/TG 4)") at DIN.
