Limiting Oxygen Index Chamber Oxygen Labs Index Apparatus with ASTM D2863

Limiting Oxygen Index Chamber Oxygen Labs Index Apparatus with ASTM D2863

Used to assess the combustion performance of the polymer under specified test conditions, the determination of polymer just maintain minimum volume percentage of oxygen concentrations of combustion. Suitable for plastic, rubber, fiber, plastic foam, film and film and textile materials such as combustion performance measurement.
