Description

ASTM D5950-02-Reapproved2007

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

ASTM D5950

Scope

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 −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 −51 to −11°C. (See Section 13.)

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

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

Note 1—The applicability of this test method on 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.
