Heat flux measurement pipe and method for determining sprinkler water delivery requirement

摘要

A device is provided for measuring heat flux from a test material exposed to a flame. The device is comprised of an elongate element defining a passageway for a fluid, a fluid flowing through the passageway, means for measuring the rate of water flow through the passageway, and a plurality of temperature-sensing elements positioned along the passageway and within the elongate element. The temperature-sensing elements are spaced from one another longitudinally with respect to the passageway. A method of evaluating fire hazards of materials in standard tests is provided which comprises measuring heat flux distribution in test fires at the moment when sprinklers would have sensed the fire and be activated, and determining the rate of sprinkler water delivery rate that will absorb the heat flux, thus controlling spread of the fire.
