Some many years ago I worked in a chem lab at a large oil refinery, running various lab tests on petroleum products, and, as I remember, the procedure was to check every batch of product (e.g., viscosity, flash point, color, etc.) whether it was lubricating oil, grease, or whatever. One would take a representative product sample, several if necessary to determine the representative nature of the sample, and test to determine that it fell with ASTM specs. For continuous processes, versus batch processes, such testing would proceed continuously, throughout two or maybe three shifts each day, to establish that the product always fell within specs. The continuous product would be dumped into tanks and held until confirming that it had passed specs. Anything not meeting specs would be dumped and rerun.
Obviously something like this could not be done by a small producer, but somehow, it would seem that a similar procedure should be approximated for small batches, if for no other reason than to prove product reliability and to avoid potential liability.
