A numerical index, the LOI, is defined as the minimum concentration of oxygen, in a nitrogen/oxygen mixture, which is required to just support combustion of the test sample under conditions of the test.
The higher the value of the LOI the greater the fire retardancy.
The LOI test conforms to the following standards.
Limiting Oxygen Index testing can be carried out by ITRI Innovation’s UK laboratory which is experienced at providing test results with a fast turnaround at very competitive rates.
