A table that is very informative is the following where for each of the 4 ABECs it is listed the max number of rpm's each is meant to safely work at:
===============================
ABEC 1 less than 25,000 rpm
ABEC 3 less than 32,500 rpm
ABEC 5 less than 37,000 rpm
ABEC 7 less than 43,000 rpm
===============================
The next point is to translate these limit rpm's in skater's speeds. To do that consider a skater with 80mm wheels. Simple algebra shows that:
ABEC1 is good for skaters going up to 190kmh (or ~110 mph);
ABEC3 is good for speeds up to 245 kmh (or ~152 mph)
and so on..
