An approach for establishing metrological traceability for measurement results from guarded-hot-plate apparatus consistent with policy at the National Institute...
The initial thermal conductivity measurements from a guarded hot plate apparatus using multiple line-heat sources are presented for specimens of high-density...
As the National Metrology Institute (NMI) for the United States, NIST, formerly the National Bureau of Standards, has provided measurement services, both...
Firebrands are a critical mechanism of fire spread in large outdoor fires, such as urban fires in Japan and WUI fires in Australia, Southern Europe, and the USA...
Fires in the wildland-urban interface (WUI) have been a large problem not only in the USA, but all over the world. From a pragmatic point of view, the WUI fire...
In WUI fires, decking assemblies have been observed to be an ignition vulnerability based on post-fire damage surveys. The Office of the State Fire Marshall...
Conductance of thin semicontinuous metallic films is measured in coplanar waveguide configuration at frequencies of 100 MHz to 20 GHz. The presented model of...
Evidence suggests that wind driven firebrand showers are a major cause of structural ignition in Wildland-Urban Interface (WUI) fires. While firebrands have...
