Defined:
Limiting Oxygen Index Tester under the conditions specified, the materials in the minimum oxygen concentration required for combustion of oxygen and nitrogen mixed gas stream. To represent the oxygen
percentage of the volume occupied by the value. The oxygen index is high that the material is nonflammable,
low oxygen index of said material is highly flammable and is generally believed that the oxygen index of <22 is
a flammable material, oxygen index between 22 --- 27 is a combustible material, oxygen index> 27 is a flame
retardant materials.
