1.1This test method covers the determination of pour point of petroleum products by an automatic instrument that applies a controlled burst of nitrogen gas onto the specimen surface while the specimen is being cooled and detects movement of the surface of the test specimen with an optical device.
1.2This test method is designed to cover the range of temperatures from −57 °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 from −51 °C to −11 °C. (see 13.4).
1.3Test results from this test method can be determined at 1 °C or 3 °C testing intervals.
1.4This test method is not intended for use with crude oils.
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6This 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.
