1、Designation:D341598(Reapproved 2011)Standard Practice forIdentification of Waterborne Oils1This standard is issued under the fixed designation D3415;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number i
2、n parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice covers the broad concepts of sampling andanalyzing waterborne oils for identification and comparisonwith suspected source oils.Detai
3、led procedures are referencedin this practice.A general approach is given to aid theinvestigator in planning a program to solve the problem ofchemical characterization and to determine the source of awaterborne oil sample.1.2 This practice is applicable to all waterborne oils takenfrom water bodies,
4、either natural or man-made,such as openoceans,estuaries or bays,lakes,rivers,smaller streams,canals;or from beaches,marshes,or banks lining or edging thesewater systems.Generally,the waterborne oils float on thesurface of the waters or collect on the land surfaces adjoiningthe waters,but occasionall
5、y these oils,or portions,are emul-sified or dissolved in the waters,or are incorporated into thesediments underlying the waters,or into the organisms livingin the water or sediments.1.3 This practice as presently written proposes the use ofspecific analytical techniques described in the referencedAS
6、TM standards.As additional techniques for characterizingwaterborne oils are developed and written up as test methods,this practice will be revised.1.4 This standard does not purport to address the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this standard to e

11、occasionally emul-sified or dissolved in the water.The waterborne oil can also befound on beaches or banks edging the water body,in thesediments underlying the water,or in the organisms living inthe water or in the sediments.3.2 DefenitionsFor definitions of other terms used in thispractice,refer to
