(Equivalent Test Method: IP 359)
TEST SUMMARY
This test method is valid in the range from 0 to 30 % by volume. Equal volumes of fuel oil and water saturated toluene are placed in each of the two cone shaped centrifuges. After centrifugation for 10 min at a rate to give between 500 and 800 relative centrifugal force (rcf), the volume of the higher gravity water and sediment layer at the bottom of the tube is read.
TEST PRECISION
See the test precision in following figure at the concentration level of 0.0 to 0.3 % water. From 0.3 to 1.0 % water, the repeatability is 0.12, and the reproducibility 0.28.
