Specimen heat fluxes for bench‐scale heat release rate testing

摘要: When a specimen is tested for its heat release rate (HRR) behavior using bench-scale test such as ISO 5660 or equivalent, one very important condition not pre-standardized and must be set : the flux to imposed on by heater. The cannot legitimately standardized, since value appropriately used will differ according purpose application. present paper sets forth considerations which should govern correct choice of flux. A discussion given minimum ignitability level ; statistical variability at low fluxes ranges associated with small actual ignition sources fires away from source, all way up fully-involved room application product needs mathematical modeling fires. Correlational approaches are also illustrated contrasted physics-based ones. Finally, empirical nature situation emphasized. Judged first principles, it would appear that successful prediction fire results data require both testing large number different use algorithms permit time-dependent interpolation. Such have been proposed however, some predictions noted much simpler techniques.
