labs in the high volume days would get (for a price) a roll of film with precise pre-exposures and notches to indicate where to cut off a sample. they would run one a day and use a densitometer to read the grey bars and plot graphs of the results. there was a chart to tell them what to adjust to get their process back in line.
Sounds like the labs in question are getting a similar strip, cut from a larger roll with various test images that Kodak's techs will read and make sure that the new film will work to spec with the processes as they exist in the field. In the old days if the lab was not using Kodak Chemicals in a Kodak, or Kodak Approved Processor, if the colour was off- the lab was wrong - these days the chemicals will likely be in a fuji-hunt bottle.
AS far as Ferrania P30 - they have dug that formula out of the archives and the last time it was made only a few formuals that are used now were available. when (fingers crossed) they get the E-6 into test status, they will likly be doing the same sort of test with at least a few E-6 labs. The P30 WAS tested by several B&W custom labs before they sold any to teh public.
