I believe acceptance testing per the current edition (2013) of this standard is governed by the formula for make-up water as Q=LDP^.5/148,000. I happen to have a 1994 edition of this same standard that you would see appears differently, at Q=NDP^.5/7,400. "Q" in both equations/versions is in effect the amount of make-up water in gallons per hour that must be added to the pipeline to maintain the pressure to within +-5psi of test pressure P in psi, "L" in the current version is the pipeline length in feet, whereas the different "N" in the 1994 version is instead the number of joints in the pipeline. The formulae look drastically different, until one realizes the most common type of pvc pipe in the USA is gasketed joint and in 20 feet lengths, and if you multiply the denominator of the 1994 equation by 20 you will in fact get the 148,000 denominator value of the current (where "N" has been replaced by "L"). In practical terms, very likely close to the "same difference". [I did see the units definition of "P" in the metric version of the testing equation in the 1994 edition of "killivolts per ampere" (that I fear may have confused at least a few of us civil engineers worldwide for some interim period!) appears instead in the latest edition as "kilopascals".]
That being said, while the amount of make-up water in a leakage test appears similar (and I guess I would be surprised if any intermediate version e.g. 2005 were different in that regard), there are some perhaps more subtle variations in other test duration/descriptions or requirements per the standards that may or may not be of any interest to or effect on some Owners. Hope this helps, and as I unfortunately do not have the 2005 version, I will like you await more learned comment.
