The purpose of the research was to evaluate the ignitability Methods 1010 (Pensky-Martens) and 1020 (Setaflash) as described by OSW Manual SW846 (1). The effort was designed to provide information on accuracy and precision of the two methods. During Phase I of the task, six standards and simple mixtures were tested. In addition, during Phase II, twelve actual wastes were tested. The results are contained in the Final Report. Based on standards and simple mixtures results, it can be concluded that no significant difference exists between the accuracy and precision of the two methods. The results of actual waste experiments however, provided information that showed significant differences between the methods. The Setaflash method, when applicable, was determined to be more accurate and more precise than the Pensky-Martens. The Pensky-Martens method is not applicable for wastes which have flash points below 13C (55F). The Setaflash method is not applicable to complex mixtures with substantial amounts of water and high surface tension.
