DUS 2331:2021, Standard Test Method for Pour Point of Petroleum Products (Automatic Tilt Method), First Edition (11 page(s), in English)

This Draft Uganda Standard 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. This test method is designed to cover the range of temperatures from –66 °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 –51 °C to –11 °C. Test results from this test method can be determined at 1 °C or 3 °C intervals. This test method is not intended for use with crude oils.
