Validation plays an important role throughout the safety system development and commissioning process. ISO/EN 13849-2:2003 sets the requirements for validation. It calls for a validation plan and discusses validation by testing and analysis techniques such as Fault Tree Analysis and Failure Modes, Effects and Criticality Analysis. Most of these requirements will apply to the manufacturer of the subsystem rather than the subsystem user.
