Standard Test Method for Pour Point of Petroleum Products (Automatic Pressure Pulsing Method)

Importancia y uso:

5.1 The pour point of a petroleum product is an index of the lowest temperature of its utility for certain applications. Flow characteristics, like pour point, can be critical for the correct operation of lubricating oil systems, fuel systems, and pipeline operations.

5.2 Petroleum blending operations require precise measurement of the pour point.

5.3 In most cases, this test method does not require the use of mechanical refrigeration apparatus (see 7.1).

5.4 This test method yields a pour point in a format similar to Test Method D97/IP 15 when the 3 °C interval results are reported.

Note 2: Since some users may wish to report their results in a format similar to Test Method D97 (in 3 °C intervals) the precisions were derived from the temperatures rounded to the 3° intervals. For statements on bias relative to Test Method D97, see 13.3.

5.5 Test results from this test method can be determined at either 1 °C or 3 °C intervals.

5.6 This test method has better repeatability and reproducibility relative to Test Method D97/IP 15 as measured in the 1992 and 1998 interlaboratory test programs.4
