This   test   method   specifies   a   procedure   for determination of the distillation characteristics of petroleum products having boiling range between 20 °C to 400 °C at atmospheric pressure using an  automatic  micro  distillation  apparatus.  The measurement is made on a small test portion.

WARNING  —  The  use  of  this  Standard  may  involve hazardous  materials,  operations  and   equipment.  This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of  the  user  of  this  Standard  to  establish  appropriate safety,  health  and  environmental  practices  and  to determine the applicability of regulatory limitations prior to use.

This test method is applicable to such products as: light and middle distillates; automotive spark- ignition  engine  fuels;  automotive  spark-ignition engine  fuels  containing  up  to  20  %   ethanol; aviation gasolines; aviation turbine fuels; regular and low sulfur diesel fuels; FAME (B100) biodiesel blends  up  to  30  %  biodiesel;  special  petroleum spirits;   naphtha’s; white   spirits;   kerosene’s; burner fuels, and marine fuels.

The test method is also applicable to hydrocarbons with  a  narrow  boiling  range, such as organic solvents or oxygenated compounds.

The  test  method  is  not  applicable  to  products containing appreciable quantities of residual material.

NOTE   Vapour  and  liquid  temperature  are  converted by an algorithm in the automatic apparatus software in order to predict distillation temperatures that would have been obtained if the material had been tested using the IP 123 test method.
