The test system uses a well-known oxygen sensor and displays the result digitally, which has the advantages of accurate judgment and good reproducibility. 1 This test method provides for the measuring of the minimum concentration of oxygen in a flowing mixture of oxygen and nitrogen that will just support flaming combustion of plastics. Such materials are solid, laminated or cellular materials characterized by an apparent density greater than 15 kg/m3. A dynamical systems model of the limiting oxygen index test: II. Retardancy due to char formation and addition of inert fillers: Combustion Theory and Modelling: Vol 5, No 1. For Powder Samples- Approx.

Scope: ASTM D2863 is a method to determine the minimum concentration of oxygen in an oxygen/nitrogen mixture that will support a flaming burn in a plastic specimen. Use of this web site signifies your agreement to the terms and conditions. The limited oxygen index test is a commonly used method for assessing the flammability of materials. PDF] Dependence of Limiting Oxygen Index of Buoyant Turbulent non-premixed Flame on Fuel | Semantic Scholar. Although devices to measure this value are commercially available, this work aims to design, fabricate, and validate an extension of these commercially available devices to a wider parameter space of interest to fundamental fire research. It is measured by passing a mixture of oxygen and nitrogen over a burning specimen, and reducing the oxygen level until a critical level is reached.

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. It is recommended to use specimens of 80 to 120mm long, 10mm wide and 4mm thick for injection molding materials. Retardancy due to char formation and addition of inert fillers.

The action of the fire retardant is investigated by unfolding this bifurcation point with a suitable continuation parameter which reflects the mode of action of the additive. Results for different materials should only be compared if the testing was done on samples of similar size. The oxygen concentration is measured using a paramagnetic oxygen analyzer and is controlled by varying the relative flow of oxygen and nitrogen through a vertical glass column. Please note that this test description is intentionally generic in nature and aimed at providing a descriptive summary to enhance test understanding.

The LOI value is also dependent on the surrounding temperature of the sample. What is the limiting oxygen index loi of pvc. Plastics and cable material is tested for its LOI value at both ambient temperature and elevated temperature to understand its oxygen requirement under actual fire conditions. ASTM D2863-17a Measuring Oxygen Index Testing on materials.

The fire retardant mechanisms that we consider are non-competitive char formation and dilution by addition of an inert filler. Minimum concentration of oxygen (in the air surrounding the sample) that will support flaming combustion. The lower the Limiting Oxygen Index, the greater the propensity of that material to ignite and burn. The operator adjusts the supply gases and uses the flow meter readings to calculate the oxygen index. What is limiting oxygen index.html. ASTM D2863-17a establishes the minimum oxygen concentration that is required to support candle-like combustion in materials. Terence Southard with Roger Quinn, Dept. This percentage of oxygen can be used as an indication of how easily a material burns. Oxygen Index ASTM D2863. 11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. That will support continuing burning.

While many designs of the LOI test apparatus calculate oxygen index based on the flow of oxygen and nitrogen, the unit incorporates a paramagnetic oxygen analyzer for precise measurement of oxygen concentration without the need for calculations and frequent recalibrations. Effects of vitiated air on radiation and completeness of combustion in propane pool fires. Depending on the type of material, Element's team of experts select one of three testing methods. This paper presents a comparative study of the extinguishment of liquid heptane and gaseous propane diffusion flames caused by the addition of flame-suppressing agents (N2 and CO2) into a coflowing….
