Standard Test Method for Distillation of Industrial Aromatic Hydrocarbons and Related Materials

SIGNIFICANCE AND USE
This test method is suitable for setting specifications, for use as an internal quality control tool, and for use in development or research work on industrial aromatic hydrocarbons and related materials.  
This test method gives a broad indication of general purity and can also indicate presence of excessive moisture. It will not differentiate between products of similar boiling range.
SCOPE
1.1 This test method covers the distillation of industrial aromatic hydrocarbons and related materials of relatively narrow boiling ranges from 30 to 250°C.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The following applies to all specified limits in this test method: for the purposes of determining conformance to this test method, an observed or calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
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, and Section 7.

a precision resistance decade box. Another technique is to
distill pure toluene and compare the temperature indicated by
the thermocouple or resistance thermometer with that shown
by the thermometer. When installing a new automatic distilla-
tion analyzer, a toluene sample with a known distillation range
of approximately 1.0°C must be used to verify the dry point

be used when replacing a temperature measuring device.
