It is suitable for testings of solid materials, laminates, foams, plastics, fabrics, films, etc. 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. The operator adjusts the supply gases and uses the flow meter readings to calculate the oxygen index. The percent of oxygen required for combustion reduces as the surrounding temperature is increased. 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. The Limiting Oxygen Index (LOI) Chamber precisely determines the relative flammability of materials. Year of Installation - 2022. The main objective of this article is to investigate the capability of the flamelet progress variable (FPV) model to capture the extinction processes observed in under-ventilated fire scenarios. It is often used in materials specifications and material/product data sheets and included in some US Mil Specs.
Instant access to the full article PDF. 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. The test method is simple: Fix the sample vertically in a glass combustion tube, and its base is connected to a device that can generate a nitrogen-oxygen mixed gas flow. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. Flammability Test - Limited Oxygen Index - Tested and certified excellence in cable protection (PMA cable protection) | ABB. Results for different materials should only be compared if the testing was done on samples of similar size. The test specimens are burned in a precisely controlled atmosphere of nitrogen and oxygen. 6 This test method is also suitable, in some cases, for cellular materials having an apparent density of less than 15 kg/m3.
Materials with an LOI greater than the atmospheric oxygen concentration are called fire retardant materials. For example, materials with established Oxygen Indices lower than 20. The limiting oxygen index (LOI) requires data that also may be used to calculate volume percentages. TEL:+886-2-27376541;). What is limiting oxygen index in chemistry. According to the type of material being tested, there are usually 6 different sample specifications. Wilton UK: - +44 1642 435 788.
