Standard Test Method for Pour Point of Petroleum Products (Automatic Air Pressure 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 systems, fuel systems, and pipeline operations.

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

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

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. However, when specification requires Test Method D97/IP 15, do not substitute this test method.

Note 2: Since some users may wish to report their results in a format similar to Test Method D97/IP 15 (in 3 °C intervals), the precision data were derived for the 3 °C intervals. For statements on bias relative to Test Method D97/IP 15, see 13.3.1.

5.5 This test method has better repeatability and reproducibility relative to Test Method D97/IP 15 as measured in the 1998 interlaboratory test program (see Section 13).
