Summary of Test Method4.1 Based on its composition, vapor pressure, expected IBP

37、or expected EP, or combination thereof, the sample is placed in oneof four groups. Apparatus arrangement, condenser temperature, and other operational variables are defined by the group in whichthe sample falls.4.2 A 100 mL specimen of the sample is distilled under prescribed conditions for the grou

38、p in which the sample falls. Thedistillation is performed in a laboratory batch distillation unit at ambient pressure under conditions that are designed to provideapproximately one theoretical plate fractionation. Systematic observations of temperature readings and volumes of condensate aremade, dep

39、ending on the needs of the user of the data. The volume of the residue and the losses are also recorded.4.3 At the conclusion of the distillation, the observed vapor temperatures can be corrected for barometric pressure and the dataare examined for conformance to procedural requirements, such as dis

40、tillation rates. The test is repeated if any specified conditionhas not been met.4.4 Test results are commonly expressed as percent evaporated or percent recovered versus corresponding temperature, eitherin a table or graphically, as a plot of the distillation curve.5. Significance and Use5.1 The ba

41、sic test method of determining the boiling range of a petroleum product by performing a simple batch distillation hasbeen in use as long as the petroleum industry has existed. It is one of the oldest test methods under the jurisdiction of ASTMCommittee D02, dating from the time when it was still ref

42、erred to as the Engler distillation. Since the test method has been in usefor such an extended period, a tremendous number of historical data bases exist for estimating end-use sensitivity on products andprocesses.5.2 The distillation (volatility) characteristics of hydrocarbons have an important ef

43、fect on their safety and performance,especially in the case of fuels and solvents. The boiling range gives information on the composition, the properties, and thebehavior of the fuel during storage and use.Volatility is the major determinant of the tendency of a hydrocarbon mixture to producepotenti

44、ally explosive vapors.5.3 The distillation characteristics are critically important for both automotive and aviation gasolines, affecting starting,warm-up, and tendency to vapor lock at high operating temperature or at high altitude, or both. The presence of high boiling pointcomponents in these and

45、 other fuels can significantly affect the degree of formation of solid combustion deposits.5.4 Volatility, as it affects rate of evaporation, is an important factor in the application of many solvents, particularly those usedin paints.5.5 Distillation limits are often included in petroleum product s
