Foam concentrate shall be sent annually to test what?

Foam concentrate should be kept ready to perform as designed, so the annual check focuses on its health and effectiveness. The test verifies the concentrate’s integrity—checking that it hasn’t degraded, separated, or become contaminated—and its performance when mixed with water. This ensures the foam will form a proper blanket, remain stable, and provide the expected extinguishing action when needed. If the concentrate has altered properties, it may not generate the foam quality required to control a fire. Color verification isn’t a reliable measure of quality, training personnel is a separate activity, and warranty matters are handled differently. The essential purpose of the annual test is to confirm the concentrate remains suitable for use.
