Good stuff... Although, bear in mind some the disadvantages as well as limitations in using this type of surface preparation for certain applications... In any event, Enjoy the "Readings" in the links below! ;)

I'll take advantage that we're talking on Smooth Clean Surface to ask you Gentlemen a question, and I confess my ignorance.
I live in a country that follows exclusively American standards throughout all engineering applications. Well, almost all engineering applications, and one of the exceptions is surface finish. For surface finish we follow ISO standard.
I know that in the USA you refer to RMS or Root Mean Square. How exactly is surface finish measured according to RMS?
Thanks for the reply.

Good afternoon Giovanni!

There are a plethora of methods to calculate surface roughness on a variety of materials so, I'll just narrow them down to metal surface roughness as best I can.

These three are probably well suited to what you're looking for with respect to references:

http://www.mfg.mtu.edu/cyberman/quality/metrology/surface.html

http://www.mfg.mtu.edu/cyberman/quality/sfinish/terminology.html

This one from Wikipedia is the one of the most thorough:

http://en.wikipedia.org/wiki/Roughness

This one is okay:

http://www.ljstar.com/design/surface_charts.aspx

This one is from "Quality Magazine":

http://www.qualitymag.com/Archives/eacd74ce57c38010VgnVCM100000f932a8c0____

This one is an article on super smooth mirror finishes:

http://www.optics.arizona.edu/jcwyant/pdf/Published_Papers/Optical_Testing/AbsoluteMeasurementOfSurfaceRoughness.pdf

This one is covers development of a basis for 3D Surface Roughness Standards:

This surface finish conversion chart is from Precision Grinding:

Here's another conversion chart:

This one is from the book: "The certified quality technician handbook" and you can read some of it in this link to Google books here:

http://books.google.com/books?id=Ok-jB2Xc4hEC&pg=PA98&lpg=PA98&dq=root+mean+square+surface+finish&source=bl&ots=bjWTiVj7iS&sig=FlkdHYok66AODaGmnAGsXzWTdvg&hl=en&ei=GOaSSpbAE4fvlAfa08SYDA&sa=X&oi=book_result&ct=result&resnum=6#v=onepage&q=root%20mean%20square%20surface%20finish&f=false

This one really is the best one I found:

http://www.bcmac.com/PDF_files/Surface%20Finish%20101.pdf

This one is on "Terahertz NDE for Metallic Surface Roughness Evaluation" :

http://www.ndt.net/article/v11n07/papers/06.pdf

http://www.leco.com/resources/met_tips/met_tip16.pdf

This article which is also from "Quality Magazine" will probably be the best one to sum up the answer your query Giovanni:

All of the other links I posted above the last one are for basic references so, Enjoy the readings!!! ;)
