BS EN 15227 specifies crashworthiness requirements applicable to new designs of:
BS EN 15227 identifies common methods of providing passive safety that can be adapted to suit individual vehicle requirements.
BS EN 15227 specifies the characteristics of reference obstacle models for use with the design collision scenarios.
BS EN 15227 also specifies the requirements and methods for demonstrating that the passive safety objectives have been achieved by comparison with existing proven designs, numerical simulation, component or full-size tests, or a combination of all these methods.
BS EN 15227 on crashworthiness requirements for the railway is useful for:
Crashworthiness is the ability to mitigate the consequences of a collision in a controlled manner and reduce the risk of injury to the occupants. BS EN 15227 provides the crashworthiness design of rail vehicle structures and the assessment process of collision scenarios with different categories.
BS EN 15227 provides active safety measures to prevent a collision from occurring and passive safety measures to reduce the consequences of an accident.
Overall, BS EN 15227 provides crashworthiness requirements to provide a level of protection consistent with the most common collisions and associated risks through the application of the design collision scenarios.
