Can of worms can of worms!
There is the simple way, then there is the correct way.
Just of interest the relevant specifications are:-

CISPIR 25 1995-11
ISO/TR 10605 1994(e)
Japanese blue book
ISO 11452 1995(e)
MIL STD 461D
ISO 7637 (Gives the impulse tests)
SAE J1112-13 1995
SAE J1113-42 1994

OK!
So for protection you can use a normal resistive divider and then pass this
into a ESD device like a California micro P002 etc.

Your main problems are susceptibility, we now are testing with values of up
to (Get this one people if you think your world is noisy! 200V/meter at
frequencies up to 0.5MHz and 40V/meter amplitude modulated by 80% up to
10MHz) Failure rates are dependant on the module requirements etc.
