I believe that the ASTM requirements don't stipulate how often you have to do testing. The local (well sort of) WVO plant here in CA (Imperial Western Products) sends out an analysis with every batch, they're apparently a batch plant. The most recent guideline that I have found for how often to QC biodiesel is from NREL in September 2001. http://www.afdc.nrel.gov/pdfs/5845.pdf See page 6, paragraph 2.

Re: [biofuels-biz] Fwd: quality control, customer service, and big industry
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.

Re: [biofuels-biz] Fwd: quality control, customer service, and big industry
The odd thing is that it is the big guys (two of them apparently in the past few weeks) who are having obvious quality control problems, and that they're not admiting it (or catching the problem) until some customer/retailer points it out (both World Energy and another producer who just recalled some fuel, which had quality problems which were also not 'caught' by the producer until a biodiesel activist/retail consumer alerted them to a problem). They presumably have the testing facilities to do this as Glenn describes. SO what's happening? mark 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.
