(Test Method)Standard Test Method for Drop Melting Point of Petroleum Wax, Including Petrolatum
Standard Test Method for Drop Melting Point of Petroleum Wax, Including Petrolatum
SIGNIFICANCE AND USE
Melting point is a wax property that is of interest to most wax consumers. It can be an indication of the performance properties of the wax. Drop melting point, Test Method D 127, is often used to measure the melting characteristics of petrolatums and other high viscosity petroleum waxes.
SCOPE
1.1 This test method covers the determination of the drop melting point of petroleum wax. It is used primarily for petrolatums and other microcrystalline wax.
Note 1—Additional methods used for petroleum waxes are Test Method D 87 and Test Method D 938. Results obtained may differ, depending on the method used. For pharmaceutical petrolatum, Test Method D 127 usually is used.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.1 Specimens are deposited on two thermometer bulbs by dipping chilled thermometers into the sample. The thermometers
bearing the specimens are placed in test tubes and heated by means of 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.
