Flame Suppression Effectiveness of Halon Alternatives (NISTIR 5499)

September 1, 1994
Author(s)
William L. Grosshandler, Anthony P. Hamins
The elimination of new production of halon 1301 has forced the manufacturers, owners, and users of aircraft to search for an alternative. The program described here developed performance screens for candidate agents as a means to identify the best

Model for the Burning of a Horizontal Slab of Wood: Status Report (NISTIR 5499)

September 1, 1994
Author(s)
Kenneth D. Steckler, Anthony P. Hamins, Takashi Kashiwagi
We are in the process of developing a burning-rate model for char-forming materials. Currently, the combustion of a horizontal slab of wood, exposed to an external radiant source, is being modeled in terms of two coupled sub-models which simulate gas and

Pipe Flow Characteristics of Alternative Agent/Nitrogen Mixtures (NISTIR 5499)

September 1, 1994
Author(s)
Thomas G. Cleary, M D. King, Jiann C. Yang, William L. Grosshandler
The evaluation of alternative agents for application in engine nacelle fire protection includes delivery efficiency of agent from a remote storge bottle through piping to the nacelle injection loacation. Present military requirements for halon systems

Pool Burning of Silicone Fluids (NISTIR 5499)

September 1, 1994
Author(s)
R Buch, Anthony Hamins, John R. Shields, P. Borthwick, R T. Baum, Marc R. Nyden, Takashi Kashiwagi
Siloxane fluids have a number of industrial applications including use as transformer fluids. The objective of the present study was to improve our understanding of the burning of siloxane fluids. The fluids studied are octamethylcyclotetra siloxane, [(CH3

Simulation: State of the Art in Japan

September 1, 1994
Author(s)
Albert W. Jones
This report summarizes the state of the art of simulation research and development in Japan. This summary is divided into three parts. In part one, we provide a translation of a paper that was published in Journal of the Operations Research Society of

Testing of Coordinate Measuring System Software

September 1, 1994
Author(s)
Cathleen Diaz, Ted Hopp
Coordinate measuring systems (CMSs) determine dimensional (length) characteristics of mechanical parts by analyzing 3-dimensional point data acquired on part surfaces. Data analysis software can contribute significantly to the total measurement error of a

The Sensitivity of Three-Point Circle Fitting

September 1, 1994
Author(s)
Ted Hopp
This paper established to first order the sensitivity of the center coordinates and radius of a circle through three points in terms of small, random perturbations of those points. This problem arises in the estimation of measurement errors, from

Santa Ana Fire Department Experiment at 1315 South Bristol, July 14, 1994. Report of Test.

August 31, 1994
Author(s)
Anthony D. Putorti Jr., William D. Walton, W H. Twilley, Scott Deal, J. C. Albers
The Santa Ana Fire Department of Santa Ana, California conducted a series of fire experiments in residences on South Bristol Street in the city of Santa Ana in July, 1994. NIST provided technical support, consisting of measurements of fire phenomena, to
