This Standard sets out requirements and guidance for the design, construction, operation and maintenance of roller coasters.NOTE: This Standard refers to roller coasters whose main characteristic is that the motion of the vehicle is produced mainly by an exchange between potential and kinetic energy, and where an initial store of potential energy is provided by an elevating, launch or self-driven system. Coasters falling into this category may employ trains of interconnected vehicles, an individual vehicle or a number of individual vehicles, and may incorporate features in their track design which cause inversions (loops) and high accelerations. They may travel in both forward and reverse directions.
