The NHRA/IHRA fuel checks are actually checked against a standard spec, issued by the race fuel manufacturer. When Renegade became an accepted race fuel for both series, we submitted the test specs of each of our fuels. Those specs are then used by the sanctioning body to make sure that the fuel you say is in the fuel cell, really is in the cell, and hasn't been altered.
Primarily, the dilectric reading of the fuel is compared to the specs supplied by the race fuel manufacturer. That's the test that can result in a DQ.
The test is very precise. So sample temps, exposure to the atmosphere, and plain old contamination can have a big influence on the outcome. Something as simple as having some of the sample fuel wash across your greasy hand and then into the sample container will have an effect. And it's not unheard of to find product right from the supplier that isn't up to spec, or was in a contaminated container.
Some brands seem to have a much bigger problem with quality control than other brands.
