3、the comparison of physical and chemical charac-teristics of the waterborne oils with oils from suspect sources.These oils may be of petroleum or vegetable/animal origin,orboth.Seven procedures are given as follows:SectionsProcedure A(for samples of more than 50-mL volumecontaining significant quanti
