3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Pour point pourpoint The lowest temperature at which the sample was observed under the conditions of this test. 3.2 Highest (upper) pourpoint The sample was subjected to a pour point observed after a specific treatment designed to promote wax crystal gelation and sample solidification. 3.3 Minimum (lower) pour point The sample was subjected to a pour point observed after a specific treatment designed to retard wax gelation and solidification of the sample.

4 Principle of the method

After the sample was preheated, it was cooled at a prescribed rate, and the flow characteristics of the sample were observed at intervals of 3 °C. Will observe the most able to flow the sample The low temperature value is recorded as the pour point of the sample.
