Critical Oxygen Index Test Apparatus - China

The Oxygen Index (LOI) fire test is perhaps the most economical and precise quality control test for combustible materials.

Its ease of use together with high levels of precision has made this technique a primary characterization and quality control tool for the plastic materials and electric cable industries.

It is often used in materials specifications and material/product data sheets and included in some US Mil Specs.

The test assesses the minimum percentage of oxygen in the test atmosphere that is required to marginally support combustion.
