This document sets out a framework to replace and/or complement physical tests with virtual tests by introducing simulation credibility for a given railway application. This covers simulation development, use, and management. Users of this document can be: - simulation engineers or organizations and their subcontractors, - standardization working groups to introduce simulations in their standards or - technical assessors and conformity assessment bodies. This document provides guidance, particularly when simulations are not yet defined. Where applicable, this document can be used in conjunction with existing standards pertaining to the use of simulations. If simulation is already recognized in existing domain-specific standards, this document does not modify the requirements of those standards. However, it may assist in future improvements and harmonization. It does not provide domain-specific guidance on applying simulations. For the use of technologies including, but not limited to, artificial intelligence, model-scale testing, and distributed computing, relevant potential technology based risks can arise.

This document is principally applicable to small craft propelled by human or mechanical power. In relation to habitable multihulls, this document includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation. This document excludes: — inflatable and rigid-inflatable craft covered by the ISO 6185 series, except for references made in the ISO 6185 series to specific clauses of the 12217 series; — personal watercraft covered by ISO 13590; — aquatic toys; — canoes and kayaks solely propelled by human power; — gondolas and pedalos; — sailing surfboards; — non-powered surfboards; — hydrofoils and hovercraft when not operating in the displacement mode; and — submersibles. NOTE Displacement mode means that the craft is only supported by hydrostatic forces. It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations or dynamic stability of high speed craft, which need to be separately considered if appropriate.
