ASTM D1160 for distillation of petroleum products at reduced pressure
ASTM D1160 standard test method for distillation of petroleum products at reduced pressure
1. Scope
1.1 This test method covers the determination, at reduced pressures, of the range of boiling points for petroleum products that can be partially or completely vaporized at a maximum liquid temperature of 400°C. Both a manual method and an automatic method are specified.
1.2 In cases of dispute, the referee test method is the manual test method at a mutually agreed upon pressure.
1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.4 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. For specific hazard statements, see 6.1.4, 6.1.8.1, 10.11, and A3.2.1.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 atmospheric equivalent temperature (AET) - the temperature converted from the measured vapor temperature using Eq A7.1. The AET is the expected distillate temperature if the distillation was performed at atmospheric pressure and there was no thermal decomposition.
3.1.2 end point (EP) or final boiling point (FBP) - the maximum vapor temperature reached during the test.
3.1.3 initial boiling point (IBP) - the vapor temperature that is measured at the instant the first drop of condensate falls from the lower end of the condenser section drip tip.
3.1.3.1 Discussion - When a chain is attached to the drip tip the first drop will form and run down the chain. In automatic apparatus, the first drop detection device shall be located as near to the lower end of the drip tip as practical.
3.1.4 spillover point - the highest point of the lower internal junction of the distillation column and the condensing section of the vacuum-jacketed column assembly.
