This standard specifies a procedure for determination of the distillation characteristics of motor gasolines, aviation gasolines, aviation turbine fuels, special boiling point spirits, naphthas, white spirit, kerosine, gas oils, distillate fuel oils and similar petroleum products. NOTE (1) - For the distillation of aviation turbine fuels and other products of such wide boiling range that the low distillation thermometer specified in Group 3 of table 1 is inadequate, this method may be applied by substituting the high distillation thermometer, together with the other test conditions specified in Group 3 (see 8.3). 1.2 The distillation (volatility) characteristics of petroleum products are indicative of performance in their intended applications. Petroleum product specifications generally include distillation limits to ensure products of suitable volatility performance. 1.3 The empirical results obtained by use of this distillation method have been found to correlate with automotive equipment performance factors and with other characteristics of petroleum products related to volatility.
