I have just done a 10/90 test and had .3 fallout. Would you bother re-reacting or would you accept that result.
I was rushed for time so didn't spend as much time as I usually would processing the batch.
As said, for an indirect injection engine, don't bother. If it was direct, common rail, ideally the dropout should be zero.
I am informed that from GC testing/10/90 test the bonded glycerine spec will just pass if the dropout does not exceed 0.15mls. This figure is based on the fact that up to 2% triglycerides will not show up on a 10/90 test due to their small solubility in methanol. This is also why if the 10/90 test shows a pass, then the conversion should be expressed as
> (greater than) 98%
