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 This test method can determine the pour point of the test specimen with a resolution of 1.0 °C. 5.4 Test results from this test method can be determined at either 1 °C or 3 °C intervals. 5.5 This test method yields a pour point in a format similar to Test Method D97/IP15 when the 3 °C interval results are reported. 5.6 This test method has better
repeatability and reproducibility relative to Test Method D97/IP15
as measured in the 1998 interlaboratory test program. (See Section
1.1 This test method covers the
determination of pour point of petroleum products by an automatic
instrument that tilts the test jar during cooling and detects
movement of the surface of the test specimen with an optical
device.
1.2 This test method is designed to cover the range of temperatures from −66 °C to +51 °C; however, the range of temperatures included in the 1992 interlaboratory test program only covered the temperature range from −39 °C to +6 °C, and the range of temperatures included in the 1998 interlaboratory test program was −51 °C to −11 °C. (See Section 13.) 1.3 Test results from this test method can be determined at 1 °C or 3 °C intervals. 1.4 This test method is not intended for use with crude oils. 1.5 The values stated in SI units
are to be regarded as standard. No other units of measurement are
included in this standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
