- Abstract
- A large number of bench-scale fire toxicity tests have been proposed over the last two decades. So far none of them has reached acceptance by ISO, by ASTM, or by the majority of professionals in this area. The reasons are varied, but a major concern has been that none of the methods were seen to adequately predict the behavior of real, large-scale, building fires. Such validation efforts have been reached on the criteria for successful validation. NIST has now completed a pilot project to addres both of these issues. In this study, systematic criteria for validation have been put forth. An initial data set has been compared against these criteria, comprising 2 bench-scale methods, 3 test materials, and a single real-scale fire scenario. The project results indicate that the course being prusued is appropriate, and provide illustrative performance data for the two bench-scale methods. The present project is a pilot study; further validaion data will have to come from additionial test materials and additional real-scale fire scenarios being examined. As a result of these studies, a factor-of-3 agreement between bench-scale and real-scale results was established as both useful and practical.
