Oxygen Index Testing
Verify the safety and compliance of your materials with precise oxygen index testing to ASTM D2863-17a standards. Our certified experts use the latest equipment to deliver accurate flammability measurements while providing comprehensive fire safety guidance, from design strategies to certification, accelerating your product development while ensuring regulatory compliance.
What is Oxygen Index Testing at Element?
Oxygen Index Testing determines the minimum oxygen concentration required to support candle-like combustion in materials. At Element, we provide ASTM D2863-17a testing using paramagnetic oxygen analyzers across multiple testing procedures. These values, known as the Oxygen Index (OI) or historically as the Limiting Oxygen Index (LOI), are critical measurements for material safety assessment.

Methods And Solutions Offered
Methods And Solutions Offered
Our testing solutions incorporate paramagnetic oxygen analysis with specialized physical support structures tailored to your material type. Element’s experts determine the oxygen concentration of a material using a paramagnetic oxygen analyzer and one of three specialized testing methods, depending on the material type.
- Procedure A: Measures top surface ignition.
- Procedure B: Measures propagating ignition.
- Procedure C: Compares the material to a pre-established oxygen concentration to assess whether combustion occurs.
Our technical experts will guide you in selecting the appropriate procedure, advising on methods, and specific oxygen index test equipment, and providing physical support structures as needed, based on the material type.
We also provide comprehensive guidance on procedure selection and detailed analysis of results, helping you understand the implications for your materials' safety performance.
- Material-specific testing configurations
- Custom physical support structures
- Detailed results analysis
- Expert procedure selection guidance
- Comprehensive documentation support
