What is LOI Testing?



What is LOI Testing?..

Answer / ravikanth

The Limiting Oxygen Index (LOI) test is a widely used
research and quality control tool for determining the
relative flammability of polymeric materials. A numerical
index, the ‘LOI’, is defined as the minimum concentration
of oxygen in an oxygen – nitrogen mixture, required to just
support downward burning of a vertically mounted test
specimen. Hence, higher LOI values represent better flame
retardancy. The test method is generally reproducible to an
accuracy of + 0.5% and although originally designed for
testing of plastics, the method has been used extensively
for evaluating the relative flammability of rubbers,
textiles, paper, coatings and other materials.
