Minimum concentration of oxygen (in the air surrounding the sample) that will support flaming combustion. There is no correlation to real end use conditions. Skip to Main Content. Samples of material are exposed to a flame within a chamber. The Limiting Oxygen Index (LOI) Chamber precisely determines the relative flammability of materials.

What Is Limiting Oxygen Index In Dogs

This is a considerable improvement over systems that use analogue gauges or require flow matching and the use of graphs or tables to calculate oxygen concentrations. The oxygen content within the controlled environment within the chamber can be varied to within 0. Issue Date: DOI: Keywords. For injection molded samples, 80 to 150 mm long by 10 mm wide by 4 mm thick is the recommended size. Ignite the top of the sample, and the oxygen concentration in the mixed gas flow will continue to decrease until the flame goes out. Types I to IV are self-supporting while Type V and VI require some form of physical support. Using a dynamical systems model an oxygen index is identified with an extinction limit point. The test specimens are burned in a precisely controlled atmosphere of nitrogen and oxygen. Limiting Oxygen Index (LOI).

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. 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). ASTM D2863-17a establishes the minimum oxygen concentration that is required to support candle-like combustion in materials.

5 This test method also provides for testing flexible sheet or film materials, while supported vertically. Since a laminar counterflow diffusion flame can be established in the stagnation…. The fire retardant mechanisms that we consider are non-competitive char formation and dilution by addition of an inert filler. That will support continuing burning. 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.
