Pour Point and Product Fluidity 1
The pour point is the lowest temperature at which a fluid will move when tilted.
The product fluidity is a measure of the ability of the fluid to flow at a specified temperature.
Foam and water enhancer concentrates are tested at 40 °F, 33 °F, and 5°F and rated as fluid,
semi solid, or solid based on observations of the product when it is tilted.
These characteristics may be significant in areas where early or late season fires occur at high
elevations and low temperatures. They may also be important in some prescribed fire
situations.
