Product emissions chamber testing involves a complex protocol with several sources of measurement uncertainty (ASTM, 2010; ISO, 2006). Despite the potential for significant variability in measurement results within and among laboratories, there is no
The flow table is a standardized test that is widely used to qualify a mortar to be tested for compressive strength and air content. It is also the only standard test to quantify a mortar workability property. Therefore, the calibration of this device is
When an emergency occurs, it is not always sufficient to simply initiate alarm bells. Individuals may not know what the alarm bell means and, in turn, respond inappropriately to its sound. Many buildings have installed mass notification or emergency
A series of experiments are described in which helium was released at constant rates into a 1.5 m 1.5 m 0.75 m enclosure designed as a -scale model of a two car garage. The purpose was to provide reference data sets for testing and validating computational

Indoor accelerated and outdoor field weathering of styrene-ethylene-butadiene-styrene block copolymer have been studied by Fourier transform infrared (FTIR) spectroscopy. In the indoor accelerated experiments, specimens are exposed to ultraviolet-visible
This report provides the technical basis for a potential new regulatory guide that would provide licensees and applicants with guidance that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for use in selecting the design

A fire occurred on the evening of June 18, 2007, in the Sofa Super Store in Charleston, SC. NIST analyzed the fire ground, consulted with other experts, and performed computer simulations of fire growth alternatives. Based on these analyses, the following

The NRC is investigating the performance of seals in SNF transportation packages exposed to fires that could exceed the HAC fire described in 10CFR Part 71, such as the Baltimore Tunnel Fire that occurred in 2001. The performance of package seals is

The study of compressed hydrogen release from high-pressure storage systems has practical application for hydrogen and fuel cell technologies. Such releases may occur either due to accidental damage to a storage tank or connecting piping, or direct PRD

The effects of ozone treatment and extraction on fungal activities of bamboo and red-oak flooring materials have been investigated. One set of wood samples was extracted with cyclohexane and ethanol for 48 hours to remove extractable compounds. Another set
This study examines the size distribution and other characteristics of firebrand exposure during the 2007 Angora Fire, a severe Wildland-Urban Interface (WUI) fire in California. Of the 401 houses that received direct interface fire exposure 61% were

An experimental campaign was undertaken to determine vulnerabilities of siding treatments and walls fitted with eaves to firebrand bombardment using the NIST Dragon installed in the Building Research Institutes Fire Research Wind Tunnel Facility (FRWTF)
High-temperature metallic seal performance tests were performed. All the tests were conducted at either 800 °C or 427 °C for 9 hours in a electrical furnace. In the three repeated tests under similar beyond-design-basis thermal exposure conditions of 9
As pointed out by the recent National Academy of Sciences report on forensic sciences, the study of fire patterns and debris in arson fires is in need of additional study and standardization. Part of the current difficulty is in determining the appropriate
Arson rates vary widely across the U.S., and much of this variation can be traced to fuel and weather factors related to ignition success and socioeconomic factors shown to influence crime rates. In criminology, it is well understood that indicators of
Due to the ban of Halon 1301 under the Montreal Protocol, new liquid fire suppressants have been proposed as possible alternatives to Halon 1301 in certain fires. It has been reported that in the case of water mist fire suppression systems, a large
A mixture fraction formulation is used to numerically simulate the two-dimensional structure of diluted axisymmetric methane-air nonpremixed counterflow flames. The size of the computational domain and the grid spacing are selected based on negligible
The suppression of low strain rate non-premixed flames was investigated experimentally in a counterflow configuration through the development of a methodology that allows establishment of laminar flames free from conductive heat losses. The method allows
The NFPA 2001 standard on the use of clean agents for the suppression of fires arose from the phase-out of Halon 1301. Standard methods exists for specifying the amount of clean agent required for Class A and Class B fires, but the recommendation for Class

Experimental and numerical studies were conducted to investigate the effect of fuel location and distribution on full-scale underventilated compartment fires in an ISO 9705 room. Heptane fuel was burned in three different fuel distributions: single

This document is intended to provide practicing engineers and building code officials with a technical resource that contains the current best practice for fire-resistant design of concrete and steel structures. The report provides a review of existing U.S
The computer model CONTAM was used to simulate the spread of smoke in a house with a working furnace during smoldering fires. Three smoldering experiments from a study on detector sensitivity and siting requirements conducted in 1975 using a two story
The scientific literature through 2005 on the effects of ventilation rates on health in non-industrial indoor environments (offices, schools, homes, etc.) has been reviewed by a multidisciplinary group of scientists from diverse fields relevant to indoor
