What is the miminum slope required for floor drain pipes diameter of 16,12 and 10mm to be self cleasing?

Hi Nimot...
Floor drains are not run in pipes that small (16 mm = 0.63 inches). Heck, most water pipes aren't even run that small... ;)
Most plumbing codes that I know of require a minimum pipe size of 2" (50.8mm) for a floor drain with a slope of 1/4" (6.35mm) per foot of piping and a vent within 5 feet of the floor drain for the floor drain to be considered part of a "self-cleansing" drain system.
A 3" (76.2mm) floor drain would have the same pitch as above.
a 4" (101.6mm) floor drain would only require 1/8" (3.175mm) per foot of piping.
Anything larger only requires the 1/8" pitch per foot.
Why exactly are you asking about such small pipe sizes? Let me know, OK?
