It defines the immunity and emission test requirements for apparatus defined in the scope in relation to the electromagnetic disturbances likely to be experienced in the railway. In particular, the test requirements represent the essential el

Test requirements are specified for each port considered. Safety considerations are not covered by this standard. In special situations, where the leve
