scope:

Specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S&T) apparatus which may interfere with other apparatus in the railway environment, or increase the total emissions for the railway environment beyond the limits defined in the appropriate standard, and so risk causing Electro-magnetic interference (EMI) to apparatus outside the railway system. Apparatus which complies with the emission levels of EN 50081-2 will meet the emission requirements of this standard. The immunity levels of EN 50082-2 will also be adequate except for the special case of apparatus installed close to the rails. This standard provides the immunity requirements for such apparatus.
