EN 50121-4 and IEC 62236-4, Track Side Approval
To fully comply with EN50121-4 and IEC 62236-4 a product must be designed
to meet a series a demanding standards covering EMC, vibration and power.
Track side installations needs to be more resistant to ESD, EFT, Surge, Radio
frequency magnetic field as well as Puls and Power magnetic ield.
The following comparison shows the difference between the test levels.
| Generic Industry | Track Side | |
|---|---|---|
| ESD | 4kV | 6kV |
| Radio frequency magnetic field | 10V/m | 20V/m |
| EFT (fast transient) | 1 kV class B * | 2 kV class A * |
| Surge Signal L-E | 1 kV | 2 kV |
| Signal L-L | N/A | 2Kv |
| AC Pow.L-E | 2 kV | 2kV |
| AC Pow.L-L | 1kV | 2kV |
| DC Pow.L-E | 0.5 kV | 2 kV |
| DC Pow.L-L | 0.5 kV | 2kV |
| Power magnetic field | 30 A/m | 300 A/m |
| Puls magnetic field | N/A | 300 A/m |
*Class A do not accept restart of the unit or loss of package or restart, class B do not accept
restart of the product but accept loss of data.
