The universal correlation for gaseous deflagration venting in coordinates "dimensionless reduced pressure -turbulent venting parameter" (Molkov, 1995) have been verified on the widened range of experimental data. These included a collection of 39 literature experimental data, processed with proposed earlier theory (Molkov et al., 1981(Molkov et al., -1995. Correlation covers the most wide range of explosion conditions at initial atmospheric pressure: enclosure volumes up to 8087 m3; vent ratios F/@I3 0,09-1,23; initially uncovered and covered vents with release overpressure 0-32 kPa and cover inertia 0-23 kgim2; maximum explosion overpressure down to 0,s kPa and up to 380 kPa; most dangerous near stoichiometric air mixtures of natural gas, methane and propane; various shapes of enclosures with ratio of sizes up to 4:l; point, plane and jet ignition; with and without complex obstacles and/or external explosions. It has been proved that the universal correlation is a reliable tool for fire and explosion safety engineering.It has been shown that best-fit method usually used by researchers for comparison of theoretical and experimental pressure-time profiles should exploit two adjustable parameters -turbulence factor x and discharge coefficient p for satisfactory results.KEYWORDS: venting of deflagration, reduced overpressure, turbulent venting parameter, correlation, theory and experiment, turbulence factor, discharge coefficient, best-fit method NOMENCLATURE A part of vent cross section area, occupied by burnt gas at a given moment As the total area of the sphere available for venting, m2
