Language in which you want to receive the document.


This document applies to cylinders for locks normally used in buildings, which are designed to be used with cylinders.
This document 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 categories of durability, two categories each for fire and corrosion resistance all based on performance tests as well as six grades of key related security based on design requirements and three grades on performance tests that simulate attack.
This document includes tests of satisfactory operation at temperatures between - 20 °C and + 80 °C. It specifies test methods to be used on cylinders and their protective measures linked with these cylinders and recommended by the manufacturer.
Corrosion resistance is specified by reference to the requirements of the European Standard EN 1670 on the protection of corrosion for locks and building hardware, see annex B.
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 this standard. Since suitability for use on fire doors is not essential in every situation, the manufacturer has the option to state if the cylinder conforms to these additional requirements or not. Unless otherwise specified cylinders shall conform to the requirements specified in the relevant European Standard EN 1634-1 or prEN 1634-2, see annex A.
Assessment of fire resistance of grade 1 doors is beyond the scope of this document.
On occasions there may be a need for additional functions within the design of the cylinder. Purchasers should satisfy themselves that the products are suitable for their intended use. Normative references
