ASTM D86 for distillation of petroleum products
ASTM D86 for distillation of petroleum products at atmospheric pressure
12. Report
12.1 Report the following information (see Appendix X5 for examples of reports):
12.2 Report the barometric pressure to the nearest 0.1 kPa (1 mm Hg).
12.3 Report all volumetric readings in percentages.
12.3.1 Manual Method - Report volumetric readings to the nearest 0.5, and all temperature readings to the nearest 0.5°C (1.0°F).
12.3.2 Automated Method - Report volumetric readings to the nearest 0.1, and all temperature readings to the nearest one tenth degree.
12.4 After barometric corrections of the temperature readings have been made, the following data require no further calculation prior to reporting: IBP, dry point, EP (FBP), decomposition point, and all pairs of corresponding values involving percent recovered and temperature readings.
12.4.1 The report shall state if the temperature readings have not been corrected for barometric pressure.
12.5 When the temperature readings have not been corrected to 101.3 kPa (760 mm Hg) pressure, report the percent residue and percent loss as observed in accordance with 10.19 and 11.1, respectively.
12.6 Do not use the corrected loss in the calculation of percent evaporated.
12.7 It is advisable to base the report on relationships between temperature readings and percent evaporated when the sample is a gasoline, or any other product classified under Group 1, or in which the percent loss is greater than 2.0. Otherwise, the report can be based on relationships between temperature readings and percent evaporated or percent recovered. Every report must indicate clearly which basis has been used.
12.7.1 In the manual method, if results are given in percent evaporated versus temperature readings, report if the arithmetical or the graphical procedure was used (see 11.6).
12.8 Report if a drying agent, as described in 7.5.2 or 7.5.3, was used.
12.9 Fig. X1.1 is an example of a tabular report. It shows the percent recovered versus the corresponding temperature reading and versus the corrected temperature reading. It also shows the percent loss, the corrected loss, and the percent evaporated versus the corrected temperature reading.
