Its full title is "Building hardware - Electrically powered hold-open devices for swing doors - Requirements and test methods". This standard covers: Please read the qualifying note at the end of the summary of the directive. This European Standard specifies requirements for separate hold-open devices and also for hold-open mechanisms incorporated in a door closer. Electrically powered hold-open devices for swing doors manufactured according to this European Standard can hold a swing door at a fixed position or can allow the door to swing freely. In each case interruption of the electrical supply will cause the controlled door to close positively. Electrically powered hold-open devices manufactured in accordance with this European Standard are recommended for use wherever there is a requirement for reliable hold-open and release of self closing fire/smoke door assemblies.
