FREEZING POINT OF HIGH PURITY HYDROCARBONS: ASTM D1015
EXPLANATION
A knowledge of the purity of the hydrocarbons is often needed to help control their manufacture and to determine their suitability for use as reagent chemicals or for conversion to other chemical intermediates or finished products. The freezing point measured by this test method when used in conjunction with the physical constants for the hydrocarbons listed in Test Method ASTM D1016, allows the determination of purity of these hydrocarbons.

TEST SUMMARY
The freezing points are precisely measured from the interpretation of time-temperature freezing or melting curves.

TEST PRECISION
Repeatability: 0.005° C
Reproducibility: 0.015° C

This test method has no bias.
