This standard applies to replanning and general refurbishment of playgrounds and open spaces to play. It shall apply mutatis mutandis for extensions and conversions as well as modernizations. This standard contains requirements and instructions for accessible planning, construction and operation. It also applies to games rooms that are partly or temporarily suitable for playing in addition to other uses. These include e. g. areas in the residential environment, in daycare facilities, sports facilities, outdoor pools, green areas and on school grounds. Construction projects for specific user groups may require additional or different requirements. This standard does not apply to pedagogically supervised playgrounds. But it can be applied accordingly.
