In this paper, tests and standards on assessing smoke toxicity of materials will be reviewed first. Toxic potency data such as EC50, LC50, IC50, LT50 and IT50 are briefly introduced and criticized for suitability to use. Whether LC50 is a good toxic potency parameter will be discussed. Preliminary tests on some of these toxic data for selected building materials commonly used will be assessed. ...

Effective mitigation of external fires on structures can be achieved flexibly, economically, and aesthetically by (1) preventing large-area ignition on structures by avoiding close proximity of burning vegetation; and (2) stopping flame travel from firebrands landing on combustible building objects. Using bench-scale and mid-scale fire tests to obtain flammability properties of common building ...

The aim of the present work was to improve study wood self-extinguishment under cone calorimeter thanks a dedicated experimental setup. A modified into double sliding in vertical orientation for studying samples extinguishment. With this new setup, external heat flux can be quickly switched from high low value seeking leading sample Samples were first submitted different fluxes (60, 82.5 and 93...
