This European Standard specifies requirements for performance and testing of mechatronic padlocks (MPs) and their keys and/or electronic keys. It establishes categories of use based on performance tests and grades of security based on design requirements and on performance tests that simulate attack. If the design incorporates mechanical security means in addition to the mechatronic means, these are also tested. This European Standard does not cover any other element of a security system, other than those directly involved in the control of a padlock. This European Standard does not cover the physical testing of multi-function devices such as Smartphones that may be used as part of the control system.
