DROP MELTING POINT OF PETROLEUM WAX: ASTM D127
(Equivalent Test Methods: IP 133 and ISO 6244)
EXPLANATION
Drop melting point test method is often used to measure the melting characteristics of petrolatums and other high viscosity petroleum waxes.
TEST SUMMARY
Specimens are deposited on two thermometer bulbs by dipping chilled thermometers into the sample. Then these thermometers are placed in test tubes and heated in a water bath until the specimens melt and the first drop falls from each thermometer bulb. The average of the temperatures at which these drops fall is the drop melting point of the sample.
TEST PRECISION
Repeatability: 0.8° C (1.4° F)
Reproducibility: 1.3° C (2.4° F)
This test method has no bias.
