Standard Test Method for Dropping Point of Waxes

Importancia y uso:

4.1 Waxes do not go through a sharp solid-liquid phase change when heated and therefore do not have a true melting point. As the temperature rises, waxes gradually soften or become less viscous. For this reason, the determination of the softening point must be made by an arbitrary but closely defined method if test values are to be reproducible.

4.2 This test is useful in determining the consistency of waxes, and as one element in establishing the uniformity of shipments or source of supply.

4.3 This test method has been found suitable for all types of waxes including paraffin, microcrystalline polyethylene, and natural waxes.
