Lab Instruments Cold Properties

Cloud Point: in petroleum products and biodiesel fuels, the temperature of a liquid specimen when the smallest observable cluster of hydrocarbon crystals first occurs upon cooling under prescribed conditions.

Pour Point: in petroleum products, the lowest temperature at which movement of the test specimen is observed under the prescribed conditions of the test.

Cold Filter Plugging Point: the lowest temperature at which a fuel will give trouble-free flow in certain fuel systems.

Freeze Point: the aviation fuel temperature at which solid hydrocarbon crystals, formed on cooling, disappear when the temperature of the fuel is allowed to rise under specified conditions of test.
