(5) Immerse the heated sample contained into the cold bath and record at very regular intervals (at least every 30 seconds) the temperature of the sample.
(6) Graphically plot the sample temperature against time elapse from the start of the test. Determine the temperatures at which there was no loss of temperature with time elapse. The first such instance as detected will be the approximate Cloud Point temperature and the second instance, if testing time is extended to the required period, will be the approximate pour point temperature of the crude oil.
