Retardancy due to char formation and addition of inert fillers. Only Enterprise limited. Reprints & Permissions. Specific hazards statement are given in Section. Procedure A measures top surface ignition. The device will be validated through a series of representative test cycles to demonstrate the capabilities of the improved design and compare with previous published data. 7 This test method measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. Since a laminar counterflow diffusion flame can be established in the stagnation…. The Limiting Oxygen Index (LOI) is one of an array of commonly used metrics for the rating of material flammability. Wilton UK: - +44 1642 435 788. The extinction of diffusion flames burning in various oxygen concentrations by inert gases and bromotrifluoromethane. The effectiveness of a gaseous agent on the fire suppression is quantified as the lowest oxygen concentration that will support combustion of a fuel, or limiting oxygen index (LOI). This systematic approach continues until the lowest oxygen concentration is determined that will support the combustion of the material. Samples of material are exposed to a flame within a chamber.

What Is Limiting Oxygen Index In Science

The limited oxygen index test is a commonly used method for assessing the flammability of materials. Abstract: The use of halons for fire fighting is being phased out due to their deleterious effects on stratospheric ozone. Procedure B measures propagating ignition, and Procedure C compares the material under test to a pre-established oxygen concentration to see whether or not combustion occurs. Through an iterative method the maximum percentage of oxygen in the air at which the sample of material extinguishes is determined. The latter are a more sensitive measure of inhibiting effect.

The advanced LOI Limiting Oxygen Index Chamber accurately determines the relative flammability of plastics and other materials, by measuring the minimum oxygen concentration that will support combustion according to ASTM D2863 and ISO 4589 specifications. Of Mechanical & Aerospace Engineering. The test results relate only to the behavior of the test specimens under the conditions of this test method and the results must not be used to infer the fire hazards of the material in other forms or under other fire conditions. 6 This test method is also suitable, in some cases, for cellular materials having an apparent density of less than 15 kg/m3. Creitz, E. C., "Inhibition of Diffusion Flames by Methyl Bromide and Trifluoromethyl Bromide Applied to the Fuel and Oxygen Sides of the Reaction Zone, "Journal of Research of the National Bureau of Standards, Vol. Germany: - 0800 5855888.
