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 inte rlaboratory 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 int ervals.  This 
test method is not intended for use with crude oils.
