Oxygen Compatibility & Materials Database

WHA maintains a detailed database of different materials’ oxygen compatibility. Information is determined through research and oxygen compatibility testing.


WHA offers free access to data related to standard and custom oxygen compatibility tests.

Non-metallic materials tests include Autogenous Ignition Temperature (AIT), Heat of Combustion (HC), Oxygen Index (OI) and Mechanical Impact (MI). Metallic materials tests include Promoted Combustion (PC), Particle Impact (PI), Heat of Combustion (HC), and Mechanical Impact (MI).
