1.1 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.
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 (1998) interlaboratory test program only covered the temperature range from −51 to −11°C.
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.
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 systems, fuel systems, and pipeline operations.
5.4 This test method yields a pour point in a format similar to Test Method D97/IP 15 when the 3°C interval results are reported. However, when specification requires Test Method D97/IP 15, do not substitute this test method.
