Summary of Test Method4.1 Based on its composition, vapor pressure, expected IBPor expected EP, or combination thereof,
35、the sample is placed inone of four groups. Apparatus arrangement, condensertemperature, and other operational variables are defined by thegroup in which the sample falls.4.2 A 100-mL specimen of the sample is distilled underprescribed conditions for the group in which the sample falls.The distillati
36、on is performed in a laboratory batch distillationunit at ambient pressure under conditions that are designed toprovide approximately one theoretical plate fractionation. Sys-tematic observations of temperature readings and volumes ofcondensate are made, depending on the needs of the user of thedata
37、. The volume of the residue and the losses are alsorecorded.4.3 At the conclusion of the distillation, the observed vaportemperatures can be corrected for barometric pressure and thedata are examined for conformance to proceduralrequirements, such as distillation rates. The test is repeated ifany sp
38、ecified condition has not been met.4.4 Test results are commonly expressed as percent evapo-rated or percent recovered versus corresponding temperature,either in a table or graphically, as a plot of the distillationcurve.5. Significance and Use5.1 The basic test method of determining the boiling ran
39、geof a petroleum product by performing a simple batch distilla-tion has been in use as long as the petroleum industry hasexisted. It is one of the oldest test methods under the jurisdic-tion of ASTM Committee D02, dating from the time when itwas still referred to as the Engler distillation. Since th
40、e testmethod has been in use for such an extended period, atremendous number of historical data bases exist for estimatingend-use sensitivity on products and processes.5.2 The distillation (volatility) characteristics of hydrocar-bons have an important effect on their safety and performance,especial
41、ly in the case of fuels and solvents. The boiling rangegives information on the composition, the properties, and thebehavior of the fuel during storage and use. Volatility is themajor determinant of the tendency of a hydrocarbon mixture toproduce potentially explosive vapors.5.3 The distillation cha
42、racteristics are critically importantfor both automotive and aviation gasolines, affecting starting,warm-up, and tendency to vapor lock at high operatingtemperature or at high altitude, or both. The presence of highboiling point components in these and other fuels can signifi-cantly affect the degre
43、e of formation of solid combustiondeposits.5.4 Volatility, as it affects rate of evaporation, is an impor-tant factor in the application of many solvents, particularlythose used in paints.5.5 Distillation limits are often included in petroleum prod-uct specifications, in commercial contract agreemen
44、ts, processrefinery/control applications, and for compliance to regulatoryrules.6. Apparatus6.1 Basic Components of the Apparatus:6.1.1 The basic components of the distillation unit are thedistillation flask, the condenser and associated cooling bath, ametal shield or enclosure for the distillation
