【摘要】: This test method covers the determination of pour point of petroleum products by an automatic apparatus that applies a slightly positive air pressure onto the specimen surface while the specimen is being cooled. This test method is designed to cover the range of temperatures from -57 to +51?C; however, the range of temperatures included in the (1998) interlaboratory test program only covered the temperature range from -51 to 11?C. Test results from this test method can be determined at either 1 or 3?C testing intervals. This test method is not intended for use with crude oils. Note 1The applicability of this test method on residual fuel samples has not been verified. For further information on the applicability, refer to 13.4. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.
