Description

ASTM D5949-08

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

ASTM D5949

Scope

1.1 This 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.

1.2 This test method is designed to cover the range of temperatures from −57 to +51°C. However, the range of temperatures included in the 1992 interlaboratory test program only covered the temperature range from −39 to +6°C and the range of temperatures included in the 1998 interlaboratory test program was from −51 to −11°C. (see 13.4).

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

1.4 This test method is not intended for use with crude oils.

Note 1—The applicability of this test method or residual fuel samples has not been verified. For further information on applicability, refer to 13.4.

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.
