A linear hereditary integral technique provides simple analytic solutions for deconvoluting thermopile and oxygen consumption data to remove the effect of instrument response time on peak and integrated heat release rate values. A comparison of corrected and uncorrected thermopile and oxygen sensor data obtained on an Ohio State University (OSU) apparatus for various materials indicates that significant errors in peak and integrated heat release rate can result from delayed instrument response to rapidly changing heat flows. However, correcting for temporal effects alone using this procedure does not account for differences between heat release rate values obtained by thermopile and oxygen consumption methods.
From the results obtained under the more standard experimental conditions on the gaseous metabolism of animals, it has been concluded that, in cold-blooded organisms, the amount of respiratory exchange rises with increasing temperatures. This rise, however, does not proceed at a uniform rate for all ranges of temperature, and, indeed, in some cases the respiratory exchange has been observed to show no change whatever at certain increments of temperature (Vernon, '95).
Prototype aircraft interior panels were installed as ceilings in a quarter-scale enclosure model lined with a non-flammable insulating material. Flashover conditions were generated by a 52-kilowatt propane burner. The heat requirements for flashover, with an inert ceiling, agreed with those predicted by an NBS correlation for full-scale room fires. The flammability of the prototype panels was experimentally found to be related to their ignition temperatures. In these tests, Nomex™ honeycomb panels with epoxy impregnated facesheets as well as those with phenolic impregnated Kevlar™, sustained ignition. The panels faced with phenolic impregnated fiberglass or graphite did not burn.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
