2、in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.INTRODUCTIONT
3、he previous version of the manual sampling practice described the various sampling methods andapparatus,with much focus on crude oils and semi-solids and solids.Also,previous versions did notsignificantly address closed or restricted sampling,which continue to become more prevalent.This version will
4、 provide guidance on manual sampling terminology,concepts,equipment,containers,procedures,and will provide some specific guidance related to particular products andtests.The type and size of the sample obtained,and the handling method,will depend on the purposefor which it was taken.Refer to the tes
5、t method for any specific sampling and handling requirementsup to the point of testing.It remains the responsibility of the subcommittee for the relevant test methodto provide guidance,or warnings,regarding sample container selection;preparation;cleanliness;heat,pressure,or light;sample size require
6、ments for testing and retention;and any other special handlingrequirements necessary to ensure a representative sample is tested.In addition to the individual test method,for guidance on container,size,mixing and specialhandling,further guidance may be provided in Practice D5854(API MPMS Chapter 8.3
7、),PracticeD5842(API MPMS Chapter 8.4),and Practice D4306.While this practice will provide some generalguidance regarding sample chain of custody,Guide D4840 should also be consulted.This document has been developed jointly between the American Petroleum Institute(API)andASTM International.1.Scope*1.
8、1 This practice covers procedures and equipment formanually obtaining samples of liquid petroleum and petroleumproducts,crude oils,and intermediate products from thesample point into the primary container are described.Proce-dures are also included for the sampling of free water and otherheavy compo
9、nents associated with petroleum and petroleumproducts.1.2 This practice also addresses the sampling of semi-liquidor solid-state petroleum products.For the sampling of greenpetroleum coke,see Practice D8145.For the sampling ofcalcined petroleum coke,see Practice D6970.1.3 This practice provides addi
10、tional specific informationabout sample container selection,preparation,and samplehandling.1.4 This practice does not cover sampling of electricalinsulating oils and hydraulic fluids.If sampling is for theprecise determination of volatility,use Practice D5842(APIMPMS Chapter 8.4)in conjunction with
11、this practice.Forsample mixing and handling,refer to Practice D5854(APIMPMS Chapter 8.3).1.5 The procedures described in this practice may also beapplicable in sampling most non-corrosive liquid industrialchemicals provided that all safety precautions specific to thesechemicals are followed.Also,ref
12、er to Practice E300.Theprocedures described in this practice are also applicable tosampling liquefied petroleum gases and chemicals.Also referto Practices D1265 and D3700.The procedure for samplingbituminous materials is described in Practice D140.Practice1This practice is under the jurisdiction of
13、ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and the API Committee on PetroleumMeasurement,and is the direct responsibility of Subcommittee D02.02/COMQ thejoint ASTM-API Committee on Hydrocarbon Measurement for Custody Transfer(Joint ASTM-API).This practice has been approved b
