There are a series of ENs, 50121, relating to EMC requirements for "railway equipment". That's all I know - I just noted in my records back in 1997 that they were starting to appear.
I also note in EN 61000-4-8 Power frequency magnetic field immunity, that 1 A/m corresponds to a free space induction of 1.26 uT, and test levels of 1, 3, 10, 30, and 100 A/m are given for continuous field.

We have a customer that is concerned about how our product, laboratory equipment, will respond to electromagnetic disturbances from a high speed train that runs close to their lab. The customer states that the disturbance will be around 0.7-1.2 m Teslar. Can someone please explain what the unit Teslar is and how that unit relates, or if it relates, to the immunity tests of EN 61000-4-3 Radiated immunity, or any other immunity test. Has anyone ever had a similar concern from a customer dealing with this type of disturbance? Your responses are appreciated.
