Dispersed Liquid Agent Fire Suppression Screening Method (NISTIR 6242)

October 1, 1998
Author(s)
Jiann C. Yang, Michelle K. Donnelly, N C. Prive, William L. Grosshandler
The recent ban on halon 1301 production (as a result of its ozone depleting potential) has resulted in an extensive search for replacements and alternatives. The applications of fire suppression efficiency screening methods constitute an important aspect

Enhancement of R123 Pool Boiling by the Addition of Hydrocarbons

October 1, 1998
Author(s)
Mark A. Kedzierski
This paper present pool boiling heat transfer data for ten different R123/hydrocarbon mixtures. The data consisted of pool boiling performance of a GEWA-T TM surface for pure R123 and for ten dilute solutions of five different hydrocarbons: (1) pentane, (2

Flammability Studies of Polymer Layered Silicate (Clay) Nanocomposites (NISTIR 6242)

October 1, 1998
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, Marc R. Nyden, James E. Brown, C L. Jackson, S M. Lomakin, E P. Giannelis, E Manias
In the pursuit of improved approaches to fire retarding polymers a wide variety of concerns must be addressed, in addition to the flammability issues. First, the low cost of commodity polymers requires that the fire retardant (FR) approach also be of low

Influence of Surface Silica on the Pyrolysis of Silicones (NISTIR 6242)

October 1, 1998
Author(s)
R R. Buch, John R. Shields, Takashi Kashiwagi, Thomas Cleary, Kenneth D. Steckler
Silicones encompass a wide variety of noval materials that find applications in virtually every major industry sector. The dominant polymer in the silicone industry is polydimethylsiloxane (PDMS). The combustion of long chain PDMS exhibits a low heat

Particle Measurements in Fe(CO)5-Inhibited Flames (NISTIR 6242)

October 1, 1998
Author(s)
M D. Rumminger, Gregory T. Linteris
Since iron pentacarbonyl (Fe(CO)5) is among the most efficient flame inhibitors ever identified, research on flame inhibition by Fe(CO5) was recently started at NIST with the goal of understanding its mechanism. Obtaining a detailed understanding of this

Particulate Entry Lag in Smoke Detectors (NISTIR 6242)

October 1, 1998
Author(s)
Thomas G. Cleary, Artur A. Chernovsky, William L. Grosshandler, Michael D. Anderson
It is well known that smoke detectors do not instantaneously respond to smoke concentration directly outside the detector. The smoke must be transported through the detector housing to a sensing location inside the detector. The sensing time lag is a

Ralph Webb: A Pioneering Proselytizer for Enhanced Heat Transfer

October 1, 1998
Author(s)
Mark A. Kedzierski
Ralph Webb, a pioneer in enhanced heat transfer, proselytizes his field for the economic and technical benefit of industry. His mission has been, and always will be, the promotion of enhanced heat transfer technology. As a result, he has been instrumental

Transient Agent, Recirculating Pool Fire (TARPF) Suppression Screen (NISTIR 6242)

October 1, 1998
Author(s)
William L. Grosshandler, Anthony P. Hamins, Kevin B. McGrattan, Cary Presser
The amount of a gaseous agent required to extinguish fires in full-scale engine nacelle tests varies greatly with the geometry of the fixture and the manner in which the flame is stabilized. It has been observed that if the test is designed to allow fuel

Using Bench Scale Fire Measurements in Large Scale Simulations (NISTIR 6242)

October 1, 1998
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, L G. Blevins
A program is underwat at NIST to develop a numerical field model, referred to as the Industrial Fire Simulator (IFS), to simulate large scale fire phenomena. Because the model is intended to simulate fire flows within buildings whose volumes are on the

Refrigerants for the 21st Century / ASHRAE/NIST Refrigerants Conference

September 1, 1998
Author(s)
Piotr A. Domanski
The goal of the 1997 ASHRAE/NIST Refrigerants Conference was to review available air-conditioning and refrigeration options in response to ozone depletion, global warming, and technology advances. The two-day program consisted of 16 invited comprehensive

Sprinkler, Smoke and Heat Vent, Draft Curtain Interaction: Large Scale Experiments and Model Development. International Fire Sprinkler-Smoke and Heat Vent-Draft Curtain Fire Test Project (NISTIR 6196-1)

September 1, 1998
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, D W. Stroup
The International Sprinkler, Smoke and Heat Vent, Draft Curtain Fire Test Project organized by the National Fire Protection Research Coundation (NFPRF) has brought together a group of industrial sponsors to study the interaction of sprinklers with roof

Summary of the Structural Performance of Single-Family, Wood-Frame Housing

September 1, 1998
Author(s)
Charles W. Yancey, Geraldine Cheok, Fahim H. Sadek, B Mohraz
A review of the structural performance of single-family, wood-frame houses is presented. The performance of these structures in selected earthquakes and hurricanes is summarized. In general, wood-frame houses performed well with relatively few instances of

The Effect of Supply Air Volume on Room Temperature Stability and Uniformity

August 3, 1998
Author(s)
Stephen J. Treado, Natascha S. Milesi-Ferretti
The effect of supply airflow rate on the thermal conditions in a high-accuracy temperature controlled laboratory space was investigated using the NIST/BFRL Temperature Control Module. Detailed measurements were conducted of air and surface temperatures

Flame Extinction by Sodium Bicarbonate Powder in a Cup Burner

August 2, 1998
Author(s)
Anthony P. Hamins
An apparatus was developed for testing the extinction efficiency of a solid powder in a coflowing non-premixed flame. Extinction measurements were performed by adding agent quasistatically to the oxidizer stream until flame extinction was observed. The

Aerodynamic Databases and Electronic Standards for Windloads

August 1, 1998
Author(s)
T Whalen, Emil Simiu, G Harris, J Y. Lin, D Surry
As part of ongoing National Institute of Standards and Technology research on the development of a new generation of standard provisions for wind loads, we present results of a pilot project on the knowledge-based estimation of wind-induced bending moments
