The application requires an accuracy class of 1/1000 mm.
The target is 9 ± 0,09 mm.
The problem is, to find a real CAPABLE solution, which can be used for SPC by everybody in...

It describes the dimensions and tolerances of the inverted flare (Bördel E) and the convex flare (Bördel F)
for the tubing of outer diameter:
4,75 mm / 6,00 mm / 8,00 mm / 10,00 mm.
The most usual dimension is 4,75 mm.
