METHOD FOR DETERMINATION OF FIRE HAZARD PARAMETERS OF MATERIALS AND DEVICE FOR ITS REALIZATION

摘要

FIELD: evaluation of fire hazard. SUBSTANCE: method for determination of fire hazard parameters of materials includes heating and ignition of material sample by means of concurrent action of heated gas flow and lasar radiation. Device for method realization has electrical furnace in form of tube with Vetoshinsky nozzle, air blower and laser with power attenuator and average power meter. Sample holder in working position is located at nozzle outlet. Laser beam is oriented to sample holder. EFFECT: higher efficiency. 2 cl, 1 dwg
