Sorry I can't give you an ICAO answer, but a practical one may help. I have flown arcs at 210 kts in small turboprops but the turn on to the Final Approach Track / Localiser really is a knife edge well over max AoB to make the turn in time, and is far too gung-ho.
The same arcs I have flown in jets and would never recommend flying clean at 210. Initial approach flap for yor type and a speed of no more than 180kts. 160kts I have seen published in the standard profiles for two of the types I've flown, both jets.
And yes, I go with a mile either side of the arc and a sensible heading for being "established".
As a previous poster said, you can fly this too much on definitive theory rather than natural experience based skill. I would say however, that you won't go wrong flying the profile printed in your ops manual.
