Abstract: Federal standards do not permit plastic thermal insulating materials to be used in the construction of mobile homes unless first approved by HUD, based on acceptance tests including full room scale fire testing. The purpose of full room scale fire testing is to evaluate the performance, under fire load, of room modules constructed with the pro- posed foam plastic insulating system by comparing the results of that system to the performance of a room module constructed with conventional materials. Since traditional fire test methods were found inadequate for this purpose, the IIT Research Institute developed under contract more realistic fire tests through experimental investigation. This report presents the results of a study to develop test methods representing other plausible fire scenarios in which cavity insulation and sheathing in the walls and ceiling of mobile homes may impact life safety or con- tribute to significant property damage. The program report is divided into the study of three major fire scenarios: (1) fires originating in usually habitated spaces, (2) electrical fires originating in wall cavities, and (3) electrical fires originating in ceiling cavities. The studies were conducted concurrently. The influence of certain parameters was greater than anticipated, requiring some retrenchment and redirection of test development. Some insight was also gained on the fire behavior of currently accepted interior finish materials singly and in combination. All tests are reported, whether or not they are directly significant to the recommended test procedures. Provided are extensive collection of photographic illustrations, numerous tables, references, and three appendices.
