LOI

The advanced LOI Limiting Oxygen Index Chamber accurately determines the relative flammability of plastics and other materials, by measuring the minimum oxygen concentration that will support combustion according to ASTM D2863 and ISO 4589 specifications. 

The test specimens are burned in a precisely controlled atmosphere of nitrogen and oxygen. The operator adjusts the supply gases and uses the flow meter readings to calculate the oxygen index.
