ASTM D938 Congealing Point of Petroleum Waxes and Petrolatum
KN-938 Congealing Point of Petroleum Waxes and Petrolatum conforms to ASTM D938 Standard Test Method for Congealing Point of Petroleum Waxes, Including Petrolatum. Congealing point is a wax property that is of interest to many petroleum wax consumers. The procedure described here measures the temperature at which a sample being cooled develops a “set” or resistance to flow. At that temperature, the wax may be at or close to the solid state, or it may be semisolid and quite unctuous, depending on the composition of the wax or petrolatum being tested. In the case of petrolatums, congealing property is associated with the formation of a gel structure as the sample cools. A sample of wax is melted and a droplet is made to adhere to the bulb of a thermometer. Using a prewarmed flask as an air jacket, the droplet on the bulb is allowed to cool at a fixed rate until it congeals. The congealing point is observed as the temperature at which the droplet ceases to flow as the thermometer is turned.

UOP 46 Apparatus for Wax Content
KN-46 Apparatus for Wax Content conforms to UOP46 Paraffin Wax Content of Petroleum Oils and Asphalts. This method is for estimating the paraffin wax content of petroleum oils and asphalts. Wax content is an empirical value dependent upon the conditions under which the wax is separated from the original material. In this method paraffin wax content is defined as the mass-percent of material precipitated when a solution of asphalt-free sample in methylene chloride is cooled to -30 C. The lower limit of detection is 5 mass-percent.
