ON INCREASING THE ACCURACY OF FIRE TESTS OF FIRE EXTINGUISHERS BASED ON AN ASSESSMENT OF THE EFFECT OF THE DISPERSED COMPOSITION OF THE POWDER ON THE FIRE EXTINGUISHING EFFECT
The drawbacks of standardized fire tests of powder fire extinguishers have been established, allowing uncertainty in terms of the method and distance of powder supply, determination of its dispersed composition, and the nozzles used. A complex indicator for assessing the fire-extinguishing efficiency of a gas-powder jet is proposed, the use of which will improve the accuracy of fire tests of powder fire extinguishers.
