Articles with the Crossref icon will open in a new tab. Flammability Test - Limited Oxygen Index - Tested and certified excellence in cable protection (PMA cable protection) | ABB. Specimens are supported vertically inside the glass column, and an ignition source is then placed in contact with the top edge of the specimen and withdrawn. 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. Adequate safeguards for personnel and property shall be employed in conducting these tests.
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. LOI has been measured for both the laminar and turbulent diffusion flames. Combustion chemistry of propane: A case study of detailed reaction mechanism optimization. What is limiting oxygen index meaning. 9 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. The test system uses a well-known oxygen sensor and displays the result digitally, which has the advantages of accurate judgment and good reproducibility.

For Powder Samples- Approx. The oxygen content within the controlled environment within the chamber can be varied to within 0. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. Fire Technol 6, 320–322 (1970). Procedure A involves top surface ignition, Procedure B involves propagating ignition, and Procedure C is a short procedure involving the comparison with a specified minimum value of the oxygen index. What is limiting oxygen index.cfm. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. 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. 1 (February 1970), pp. That will support continuing burning. Fire and Flammability Testing.
Environmental ScienceCombustion Theory and Modelling. The fire retardant mechanisms that we consider are non-competitive char formation and dilution by addition of an inert filler. What is limiting oxygen index loi. The unit gives continuous digital readout of oxygen concentrations in the test atmosphere to facilitate quick settings of test concentration. Oxygen index methods are widely used to measure the flammability of polymers and to investigate the effectiveness of fire retardants. Only when the specifications of the test specimens are the same, the test results between different materials can be compared with each other.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Possible improvements in the procedure are suggested. Ignite the top of the sample, and the oxygen concentration in the mixed gas flow will continue to decrease until the flame goes out. The unit has been designed to be compact for efficient use in a standard fume cupboard (or under a simple ventilation hood that we can also supply if required).

What Is Limiting Oxygen Index Meaning
The Limiting Oxygen Index (LOI) is one of an array of commonly used metrics for the rating of material flammability. Using a dynamical systems model an oxygen index is identified with an extinction limit point. This systematic approach continues until the lowest oxygen concentration is determined that will support the combustion of the material. Issue Date: DOI: Keywords. Types I to IV are self-supporting while Type V and VI require some form of physical support. Since a laminar counterflow diffusion flame can be established in the stagnation….
Cited by lists all citing articles based on Crossref citations. Standards can be obtained from appropriate standard authorities. Some limiting oxygen concentrations for diffusion flames in air diluted with nitrogen. The LOI value is also dependent on the surrounding temperature of the sample.
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. The relative flammability is supported by measuring the minimum oxygen concentration combustion based on JIS K7201, ASTM D2863 and BS2782 Pt1 Method 141A-D specifications. This percentage of oxygen can be used as an indication of how easily a material burns. 4 This test method provides for testing materials that are structurally self-supporting in the form of vertical bars or sheet up to 10. A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. We investigate which types of material are best retarded by each mechanism. 2 This test method provides three testing procedures. Modelling extinction/re-ignition processes in fire plumes under oxygen-diluted conditions using flamelet tabulation approaches.
