EUROLAB laboratory provides testing and compliance services within the scope of EN 50121-3-1 standard. This part of the EN 50121 standard specifies emission and immunity requirements for all wagon types. Includes traction stock, towed stock and trainsets, including urban vehicles for use on city streets. This European standard sets the emission limits of wagons to the outside world.
The scope of this part of the standard ends at the interface of the relevant energy inputs and outputs and wagons. Locomotives, train sets, trams, etc. in the case of it, it is the current collector (pantograph, shoe assembly).
In the stock pulled case, this is the AC or DC auxiliary power connector. However, since the current collector is part of the traction stock, it is not possible to completely exclude the effects of this interface with the power supply line. The slow motion test is designed to minimize these effects.
There may be additional compliance requirements within the railway system defined in the EMC plan (eg as specified in EN 50238). Basically, all apparatus to be integrated into a vehicle meet the requirements of EN 50121-3-2. In exceptional cases where the device meets another EMC Standard but full compliance with EN 50121-3-2 has not been demonstrated, EMC is ensured by adequate integration measures of the device into the vehicle system or by a suitable EMC analysis and testing.
It justifies the deviation from EN 50121-3-2. Electromagnetic interference for the railway system as a whole is covered in EN 50121-2. These special provisions will be used in conjunction with the general provisions in EN 50121-1. The frequency range considered is from 0 Hz (DC) to 400 GHz.
High-power electronic equipment is installed on trains in large numbers, along with low-power microcontrollers and other electronic devices. Electromagnetic compatibility therefore became a critical issue for the design of the train as a whole, as well as the train-related apparatus.
This product standard for rolling stock sets limits for electromagnetic emission and immunity to ensure a well-functioning system in its intended environment.
Immunity limits are not given for the complete vehicle. 3-2 of this standard. The part defines the requirements for the apparatus mounted on the rolling stock, as it is impractical to test the complete unit. An EMC plan will be established for equipment covered by this standard.
