Product Description
OSU Heat Release Rate Tester for Aircraft Materials
The OSU Rate of Heat Release Apparatus is an essential testing instrument for evaluating the fire resistance of aircraft interior materials. This equipment strictly complies with U.S. Federal Aviation Administration (FAA) regulations 14 CFR Part 25.853(d) and Appendix F Part IV, as well as Chapter 5 of the FAA Aircraft Materials Fire Test Handbook. Developed by Ohio State University, this instrument simulates real aircraft cabin fire conditions using a radiant heat flux of 35 kW/m² to test heat release rates of large-area cabin materials.
The system accurately measures peak heat release rate (≤65 kW/m²) and total heat release over 2 minutes (≤65 kW*min/m²), known in the industry as the "65/65" standard. This enables material suppliers and aircraft manufacturers to ensure their products meet FAA certification requirements, significantly enhancing aircraft cabin fire safety.
Compliance Standards
FAA 14 CFR Part 25, Appendix F, Part IV: Test Method to Determine the Heat Release Rate from Cabin Materials Exposed to Radiant Heat - Core regulatory basis for OSU heat release rate testing of aircraft cabin materials.
FAA Aircraft Materials Fire Test Handbook - Chapter 5: Heat Release Rate Test for Aircraft Materials - Detailed test procedures equivalent to Appendix F Part IV requirements.
ASTM E906 / ASTM E906-14 (Revised Version): Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter - Revised OSU version commonly used in aerospace industry testing.
Test Material Applications
- Interior ceiling panels (excluding lighting lenses and windows)
- Interior wall panels (excluding lighting lenses and windows)
- Blockers (excluding transparent panels required for cabin safety)
- Galley structures, including storage trolleys, standard containers, and exposed cavity wall surfaces
- Large cabinets and cabin storage compartments
- Overhead bin linings and partitions
