ASTM D1078 Test Method for Distillation Range of Volatile Organic Liquids
1. Scope
1.1 This test method covers the determination of the distillation range of liquids boiling between 30 and 350°C, that are chemically stable during the distillation process, by manual or automatic distillation procedures.
1.2 This test method is applicable to organic liquids such as hydrocarbons, oxygenated compounds, chemical intermediates, and blends thereof.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.

3. Terminology
3.1 Definitions:
3.1.1 initial boiling point, n - the temperature indicated by the distillation thermometer at the instant the first drop of condensate leaves the condenser tube.
3.1.2 dry point, n - the temperature indicated at the instant the last drop of liquid evaporates from the lowest point in the distillation flask, disregarding any liquid on the side of the flask.
3.1.3 decomposition point, n - the thermometer reading that coincides with the first indications of thermal decomposition of the liquid in the flask.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 final boiling point, n - the maximum thermometer reading obtained during the test.
3.2.1.1 Discussion - This usually occurs after the evaporation of all liquid from the bottom of the flask. The term "maximum temperature" is a frequently used synonym.
3.2.2 end point 5 minutes, n - the thermometer reading obtained 5 min after the 95 % distillation point if no dry or final boiling point occurs.
