Standard Test Method for Pour Point of Petroleum Products (Rotational 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, such as pour point, can be critical for the correct operation of lubricating systems, fuel systems, and pipeline operations.

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

5.3 This test method can determine the temperature of the test specimen with a resolution of 0.1 °C at which either crystals have formed or viscosity increases sufficiently to impede movement of the petroleum product.

5.4 This test method yields a pour point in a format similar to Test Method D97/IP15 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 for the temperatures rounded to the 3 °C intervals. For statements on bias relative to Test Method D97, see 13.3.

5.5 This test method has better repeatability and comparable reproducibility relative to Test Method D97 as measured in the 1992 interlaboratory program. (See Section 13.)
