WebThe terms flammability limit (FL) and explosion limit (EL) have often the same meaning. In Europe the term “explosion limit” is frequently used as in the ATEX directives and in EN 13237:2012 [6]. In the US literature and in international standardization the wording “flammability limit” or “flammable limit” is more common.
