The Insulation Burnthrough test is used to evaluate the burnthrough resistance characteristics of thermal and acoustic insulation material when exposed to a high-intensity open flame.
*Subcontracted in accordance with ISO/IEC 17025
A test sample consisting of two insulation blankets is placed onto a test fixture at an angle of 60 degrees. The sample is exposed to a high-intensity open flame for four minutes. The pass/fail criteria is based on flame penetration and a maximum heat flux value on the backside of the sample.
This test is typically used to show compliance with the following Federal Aviation Regulations (FARs):
