TEST SUMMARY
A grease sample in a test cup is supported in a test tube placed in an aluminum block oven at a preset constant temperature. A thermometer is positioned in the cup so that it measures the temperature without coming in contact with the grease. As the temperature increases, a drop of material will fall from the cup to the bottom of the test tube. Temperatures of both the thermometer and that of the block oven are recorded at this point. One third the difference between the two values is the correction factor which is added to the observed value, and reported as the dropping point of the grease.
TEST PRECISION
The following precision can be expected.
