Hello,
on the website of my company you can find a list of papers on the subject of crystal measurement techniques.
http://www.axtal.com/English/TechnicalNotes/TechnicalArticlesPublications/LiteratureaboutQuartzCrystals/

The actual standard procedure for crystal  measurement is by using modern network analyzers with error correction, as given in the IEC publication 60444-5. 
A description of the method and its variants can be found in my 2012 paper listed on the mentioned website.
Enjoy

Hi Luciano:

I have some web pages about crystals and testing them:
http://www.prc68.com/I/CrystalImpedanceMeters.html - Crystal Impedance Meters (Saunders 150) http://www.prc68.com/I/Xtal.shtml#TE - Crystals in general & Test Equipment (see Trivia below) http://www.prc68.com/I/Xam.html - Crystal Activity Meters http://www.prc68.com/I/Xec.shtml - Equivalent Circuit http://www.prc68.com/I/4395A.shtml#ZT - The Z transform method is also used in commercial crystal test sets like the HP E4915, E4916, E5100.

Trivia: The HP 4194 may be the only instrument that can really characterize watch crystals ( 32768 Hz) for impedance which is in the meg Ohms range.  Some of the HP network analyzers can fit swept frequency data into an equivalent crystal equivalent circuit.

Have Fun,
