Abstract : This report supplements the description of the methodology developed for ranking cabin materials for combined hazards generated in a survivable crash fire presented in Part I of the report. More comprehensive procedures are presented for the calibration and operation of the computer-augmented Ohio State University Calorimeter modified to derive the new materials fire hazards testing apparatus known as the Combined Hazards Analysis System (CHAS). Definitive derivations of the human survival models for temperature, smoke, and toxic gases used in the hazards analysis and a thorough presentation of the mathematics used in the Fortran Fire Analysis Computer Program are presented. A full description of the full-scale fire testing method used during the development and demonstration phases of the program is presented to give a better understanding of the capability of the laboratory methodology to rate materials on the basis of the relative passenger escape time potential from a cabin section. Part II is, essentially a working manual which will assist greatly those committed to duplicating and successfully operating the CHAS. The CHAS methodology is useful for development of new fire resistant materials. (Author)
