Heat Release Rate (OSU)
Heat Release Rate (OSU)*
The Heat Release Rate (OSU) test is used to determine the heat release rates of cabin materials when exposed to radiant heat.
*Subcontracted in accordance with ISO/IEC 17025
A test sample is placed vertically 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 criteria is based on the heat release rate calculated from this data.
This test is typically used to show compliance with the following Federal Aviation Regulations (FARs):
