1、Designation:D80102(Reapproved 2013)Standard Test Methods forSampling and Testing Dipentene1This standard is issued under the fixed designation D801;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in
2、 parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover procedures for sampling andtesting dipentene and related terpene solvents,consistingchiefly of monocyclic terpene hydrocarb

7、or Sampling Industrial Chemicals3.Significance and Use3.1 The testing procedures described in these test methodshave been in use for many years and emphasize the physicalproperties rather than the chemical composition of dipentene.These procedures were sufficient when dipentene was usedprimarily as
8、a solvent.Currently,however,dipentene findsapplication as a chemical raw material and a knowledge of itschemical composition is therefore important.Test MethodsD6387 describe a capillary gas chromatography method whichis suitable for determining both the major and minor compo-nents found in dipenten
9、e.4.Sampling4.1 Sample the material in accordance with the proceduredescribed in Guide D268 and Practice E300.If a sample fromclose to the bottom of a tank shows a decided difference incolor or appearance from samples taken at other depths,take anextra bottom sample and examine it separately from th
10、ecomposite sample.In such case the composite sample shall notinclude any portion of such bottom sample.5.Detection and Removal of Separated Water5.1 Draw a portion of the dipentene by means of a glass ormetal container with a removable stopper or top,3or with athief,from the lowest part of the conta
11、iner,or by opening thebottom valve of the level tank car.If water is found to bepresent,draw it all out,record the quantity,and deduct it fromthe total volume of liquid delivered.6.Appearance6.1 Examine a portion of the sample after agitation todetermine its clarity and freedom from foreign matter a
