Comparison Of Smoke Densities From The OSU Rate Of Heat And Smoke Release Apparatus And The NBS Smoke Chamber |
| Author: |
Eldon B. Nicholas |
| Abstract: |
Smoke density tests were conducted on four aircraft cabin materials representing different usage catergories. These tests were to determine if there was any relationship between results obtained from the OSU rate of heat and smoke release apparatus and the NBS smoke chamber.
A definative statement on the relationship between the two test methods cannot be made based on the limited scope of this study. However, the materials (panels and thermoplastic) and lower values for the fibrous type materials (fabrics and carpet). |

Pressure Modeling Of Vertically Burniing Aircraft Materials |
| Author: |
R.L. Alpert |
| Abstract: |
The possibility of evaluating relative rates of upward fire spread on aircraft cabin materials is investigated with small-scale models burned at elevated' ambient air pressure. The modeling technique, which preserves the fluid Grashof number of the full-scale fire spread process, is verified in the first part of the study with vertical walls of polymethyl methacrylate (PMMA) fuel ignited at one atmosphere (full-scale) and at elevated absolute pressures (model) to 3.5 MPa (515 psia). In the second phase of the study, fifteen aircraft cabin samples are subjected to a small PMMA ignition source ,for a range of elevated ambient air pressures. Rates of upward fire spread, characterized by flame height exponential growth factors, are measurable for nearly all the aircraft cabin materials at absolute pressures from 1.18 MFa (165 psia) to 3.2 Mfa (465 psia). Ranking of the materials by rate of upward fire spread is facilitated by the nearly two order of magnitude separation between highest and lowest growth factor at each pressure level. This ranking is found to be reasonably independent of pressure, enabling conservative predictions of upward spread behavior at one atmosphere to be made. |

The Fire Safety of LS Neoprene Mattresses in Institutions |
| Author: |
R.H. Morford |
| Abstract: |
There have been large numbers of fires caused by vandalism and arson of foam products such as mattresses in various institutions such as prisons, hails and mental institutions. These fires that have been responsible for many deaths, injuries and large loss, have been the basis for many legal actions against the authorities responsible for the maintenance of the various institutions. |

Flash-Fire Propensity and Heat-Release Rate Studies of Improved Fire Resistant Materials |
| Author: |
Larry L. Fewell |
| Abstract: |
Twenty-six improved fire resistant materials were tested for flash-fire propensity and heat release rate properties. The tests were conducted to obtain a descriptive index based on the production of ignitable gases during the thermal degradation process and on the response of the materials under a specific heat load. |

Pool Fire Radiation Through A Door In A Simulated Aircraft Fuselage |
| Author: |
Thor I. Eklund |
| Abstract: |
This study evaluates small-scale methods of simulating postcrash fuel spill fires adjacent to fuselage open doors. Pool fires in a quiescent environment were scaled down and their radiant heat transfer through fuselage doorways evaluated. Steel ducts of 1, 2, 3, and 4 foot diameter were employed and matched with the experimental heat fluxes at two locations within each model. The analysis demonstrates that the doorway can be treated as a radiating black body surface of l,874 degrees Fahrenheit (F), and that heat fluxes to other areas around the doorway can be calculated. A comparison of heat flux to he model exterior was compared with existing full-scale fire test data. |
