Element performs ASTM D2863-17a testing for materials manufacturers to establish the minimum oxygen concentration value required to support candle-like combustion and safe limits for fabrics, polymers, cables, laminates, nylon, rubber, etc. 


Performing Oxygen Index Testing 

Oxygen concentration values are known as the Oxygen Index (OI) or, historically, the Limiting Oxygen Index (LOI). Depending on the type of material, Element’s experts use a paramagnetic oxygen analyzer and one of three testing methods to measure the oxygen concentration of a material. 


  • Procedure A - measures top surface ignition
  • Procedure B - measures propagating ignition
  • Procedure C - compares the material under test to a pre-established oxygen concentration to see whether or not combustion occurs.


Our technical experts will advise you on the correct procedure to follow, covering methods, particular oxygen index test equipment, and provide physical support structures, where required, depending on the material type.
