1、Designation:D332607(Reapproved 2017)Standard Practice forPreparation of Samples for Identification of WaterborneOils1This standard is issued under the fixed designation D3326;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year o
2、f last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the preparation for analysis ofwaterborne oils recovered from water.The identification isbased upon
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
