Agent Stability Under Storage and Discharge Residue (NIST SP 861)

April 1, 1994
Author(s)
Richard D. Peacock, Thomas G. Cleary, Richard H. Harris Jr.
Halon 1301 is known to be stable in metal containers for many years. Any by-products do not affect its fire suppression effectiveness or result in an unacceptable residue. For candidate replacement chemicals, comparable data are needed, reflecting the

BFRL Fire Publications, 1993.

April 1, 1994
Author(s)
Nora H. Jason
Building and Fire Research Publications, 1993 contains references to the publications prepared by the members of the Building and Fire Research Laboratory (BFRL) research staff, by other National Institute of Standards and Technology (NIST) personnel for

Calculating Flame Spread on Horizontal and Vertical Surfaces.

April 1, 1994
Author(s)
Walter W. Jones, G N. Ahmed, M A. Dietenberger
The flame spread model described in this paper is a new algorithm which provdes the capability to calculate a self-consistent fire based substantually on bench scale fire data. The flame spread model simulates object fire growth and burnout of a slab in a

Combined Buoyancy- and Pressure-Driven Flow Through a Horizontal Vent.

April 1, 1994
Author(s)
Leonard Y. Cooper
Combined buoyancy- and pressure-driven (i.e., forced) flow through a horizontal vent is considered where the vent-connected spaces near the elevation of the vent are filled with fluids of different density in an unstable configuration, with the density of

Concept for an Algorithm Testing & Evaluation Program at NIST

April 1, 1994
Author(s)
Cathleen Diaz
This report proposes a NIST service for testing and evaluating coordinate measuring systems (CMS) software. This program addresses industry need for a formal mechanism that tests data analysis software used in CMSs. The NIST Algorithm Testing and

Design Engineering Research at NIST

April 1, 1994
Author(s)
Kevin W. Lyons, Peter Brown
The National Institute of Standards and Technology (NIST) has established an Engineering Design laboratory (EDL) to assist in determining the best practices and methods to design new products and processes. This paper includes a description of issues

Executive Summary (NIST SP 861)

April 1, 1994
Author(s)
William L. Grosshandler, Richard G. Gann, William M. Pitts
Bromotrifluoromethane (halon 1301 or CF3Br) has been the fire-fighting agent of choice for decades to protect inaccessible spaces aboard aircraft in flight because of its inherent ability to inhibit combustion while possessing a high liquid density and

Flame Inhibition Chemistry and the Search for Additional Fire Fighting Chemicals (NIST SP 861)

April 1, 1994
Author(s)
Marc R. Nyden, Gregory T. Linteris, Donald R. Burgess Jr., P R. Westemoreland, Wing Tsang, Michael R. Zachariah
Replacements for the current commercial halons should posses a diverse set of properties which are rarely found together in the same molecule. Thus, the ideal candidate for the replacement of halon 1301 would be a nontoxic gas which is reactive in flames

Flame Suppression Effectiveness (NIST SP 861)

April 1, 1994
Author(s)
Anthony P. Hamins, G. Gmurczyk, William L. Grosshandler, R. G. Rehwoldt, I Vazquez, Thomas G. Cleary, Cary Presser, K Seshadri
A flame will be extinguished when the time required for the chain reaction which sustains combustion exceeds the time it takes to replenish the necessary heat and reactants. A characteristic time for reaction can be estimated from the inverse of a global

Fluid Dynamics of Agent Discharge (NIST SP 861)

April 1, 1994
Author(s)
William M. Pitts, Jiann C. Yang, G. Gmurczyk, Leonard Y. Cooper, William L. Grosshandler, W G. Cleveland, Cary Presser
The extinguishment of a fire using gaseous agents is a very complicated process which is not completely understood. Current fire-fighting agents such as halon 1301 and halon 1211 are believed to function by a combination of chemical (catalytic removal of
