6. In the test with the 1.36 cm thick panel (Test 2), the temperature rise during the
test indicates that if the initial temperature was less than 22°C, the sample may
have met the temperature requirement. As the results, the required thickness of
S-S CMF panel for full-scale torch fire testing to address all requirements of 49
CFR 179, Appendix B must be in the range of 14–15 mm.
7. The presence of air within S-S CMF porosities acts as an insulator, which is
similar to other insulating foams such as styrofoam, insulating foam boards and
spray foams.
8. This research indicates that one of the potential applications of lightweight S-S
CMF can be in tank cars carrying hazardous materials and replacing conventional structural steel with demonstrated benefits of excellent thermal insulation, fire resistance, low weight along with its established energy absorption
capabilities.
9. To complete the full-scale test requirements of CFR Part 179 App. B, panels of
122 × 122 cm dimensions will need to be tested against the torch fire exposure
in duplicate.
10. Future studies consider measurement of surface emissivity of S-S CMF at higher
temperatures to evaluate the percentage of the torch fire absorbed by the material.
