Hi Borada,
If you look at Zurich LSZH ILS 16 minima:
Jeppesen shows Cat 1 DA 1590 ft Note 1 = " 5% Missed Apch climb gradient min".
or CAT 1 C: 1825 ft. 2.5%.
So if you want to operate down to 1590 ft DA, you have to prove that you can make 5% engine out with the actual prevailing conditions. You should have a way to do the calculation - else you'll be restricted to 1825 ft DA.
There are lots of them around e.g.
Salzburg Special ILS DME Rwy 16 (5.9%)
Naples ILS Z Rwy 06 (5.2%)
