Abstract: Based on the analysis of literary sources, it was found that the parameters of the ignition sources necessary for the creation of equipment for testing aerosol sprayers according to the methods specified in the Technical Regulations for Aerosol Sprayers have not been studied sufficiently. According to the results of experimental studies of the flame temperature of candles of different diameters, the nature of their combustion, the parameters were established at which the candle has the highest flame temperature, demonstrates the most stable combustion in the event of the action of air masses, and the maximum flame temperature of the candle flame was recorded. A candle with the specified parameters is recommended as a source of aerosol ignition in a fire chamber when creating equipment for testing aerosols for flammability in a confined space. According to the results of studies of burners, in particular their temperature regimes, flame flame parameters, it was found that the most optimal for igniting aerosols and solids is a Bunsen burner with the specified parameters. It has been experimentally confirmed that propane-butane is the optimal gas for the operation of the burner, which is used to ignite aerosol or solids during flammability testing, because propane-butane allows you to obtain the required flame torch temperature of 1000 ° C, as well as achieve a stable blue flame with a height of 40 - 50 mm. The technical characteristics of the elements of the equipment for testing aerosol sprayers have been substantiated and the prerequisites for its creation have been created.
