FCI 70-2-2003 1

[NGiLuzzu]

I'm going to examinate the Fluid Controls Institute standard FCI 70-2-2003 about Control Valve Seat Leakage (formerly known as "ASME 16.104&quot, with reference to its previous edition (1991).
Has anybody already faced this comparison?
I've already noticed the extension of Leakage Class V to air (instead of water only). Are there other important changes?

Many thanks, 'NGL

Please take also a look at Thread408-122060 about the standard in object.
