Scope
This standard covers on-board devices/systems@ with crashworthy memory@ that record data to support accident/ incident analysis for rail transit vehicles. The requirements of this standard are limited to event recorder functions and interfaces@ exclude the data transmission method(s)@ and are independent of the hardware and/ or software employed for other vehicle systems. Functions@ parameters@ signals@ systems@ and subsystems that shall be captured are identified. Diagnostic features or self-test options are described.
