ASTM D6482 Determination of Cooling Characteristics of Aqueous Polymer Quenchants by Cooling Curve Analysis with Agitation (Tensi Method) When metals are heated to high temperatures and formed into desired products, they must then be cooled to room temperature. To achieve the best properties, such as hardness, the metal is placed in a quenching fluid to cool quickly and evenly. This test determines the cooling profile for sample quenching fluids. A nickel alloy probe is placed in a furnace and given time to heat to the test temperature. The hot probe is placed in the test sample, and data is collected as the sample cools. Reported is the maximum cooling rate, cooling rate at 300ºC and the quenching time to 600ºC, 400ºC and 200ºC.
