This month,we produced the first OSU Heat Release Rate Test System in China.

The OSU heat release rate test equipment, originally designed by Smith of Ohio State University in 1972, became FAA's designated combustion tester. The test standards are FAR Part 25 Appendix F Part IV, Airbus AITM 2.0006, Boeing BSS 7322 and ASTM E906.

The Heat Release Rate (OSU) test is used by the aerospace/aviation industry to determine the heat release rate of cabin compartment materials when exposed to radiant heat. It is most commonly used to show compliance with 14 CFR 25.853(d).

A test sample is placed into a chamber with a constant flow of air. A radiant heat source is applied to the exposed surface of the sample. The changes in temperature of the gas are monitored and recorded. The pass/fail criterion is based on the heat release rate calculated from this data.
