This report documents a series of fire experiments performed within steel electrical enclosures and on open "ladder back" cable trays. The first objective is to measure the heat release rates and qualitatively understand the burning behavior of circuit

Predictions of fire phenomena such as flame structure, stability, and growth made by computational fire models can be improved by incorporating an accurate description of the gaseous volatiles released by combustible solids during pyrolysis. The difficulty
T The combustion of vegetative fuels or biomass has important applications in energy generation, wildfire spread, and structural fire safety. It is critical to be able to accurately quantify the energy content of these fuels (i.e., their respective heats
This study examines variations in fire behavior among over 20 commercially available poly(methyl methacrylate) (PMMA) samples from different suppliers. Previous studies, have demonstrated the importance of kinetic parameters — describing thermal

In order to predict fire phenomena such as flame structure, stability, and growth, computational fire models require an accurate description of the gaseous volatiles released by combustible solids during pyrolysis. The difficulty in this characterization
Combustion of biomass and woody fuels is relevant to energy generation, wildfire spread, and structural fire safety. It is critical to be able to accurately quantify the energy content of these fuels (i.e., their heats of combustion [kJ/g]) and where this

16 Cone calorimetry and anaerobic gasification experiments are often used to assess material 17 flammability of bench-scale (coupon sized) samples in response to well-characterized external radiant 18 heating. In this project, it has been observed that the

Vinyl siding has become a popular choice for residential exteriors across the United States. In its insulated form, this siding includes a shell, capstock, and substrate, that encase a foamed material, serving as an efficient insulating material. While it

This paper provides an overview of selected measurements from a series of 90 full-scale fire experiments quantifying the impact of material composition on full-scale burning and fire growth behavior. Samples were selected to provide a wide range of
7 The fire modeling community is actively working to develop the tools needed to quantitatively predict material 8 and product flammability behavior (e.g., ignition, burning rate, fire growth). Such predictions require accurate 9 and efficient simulation

This report provides an overview of quantitative measurement data and visual observations obtained from a series of 52 full-scale fire growth experiments conducted on 16 unique combustible solids including: natural and synthetic polymers, copolymers
Residential upholstered furniture (RUF) is the leading combustible in fatal fires in the United States. In the last few decades, fire-retardant (FRs) chemicals have been largely used in attempt to reduce RUF flammability; however, concerns about possible
In this work, we compiled and evaluated various properties pertaining to the heats of combustion of about 420 compounds of physical, chemical, and engineering interest. This includes boiling points, melting points, latent heats (enthalpies) of vaporization

12 This poster presents Fire Dynamics Simulator (FDS) simulations of anerobic, PMMA, gasification tests 13 performed by the National Institute of Standards and Technology for MaCFP-3. 14 Five sets of simulations where performed: 15 1. Simulations of an
An upward, buoyancy-driven flame spread on combustible solids is frequently the dominant contributor to the growth of fire in built environment. Thus, an ability to accurately predict the development of a fire is strongly linked to the accuracy of flame

The use of wood in home and commercial structures has continued to grow in recent years, but its flammability poses a threat to lives and property. Previous attempts to flame retard wood have utilized harmful halogenated chemistries or required complex
This manuscript presents new measurement data from milligram-scale thermal decomposition experiments - thermogravimetric analysis (TGA) and microscale combustion calorimetry (MCC) – conducted on stems and leaves of six plant species commonly found across

The International Association for Fire Safety Science (IAFSS) Working Group on Measurement and Computation of Fire Phenomena (i.e., the MaCFP Working Group) has been established as a global collaborative effort between experimentalists and modelers in the
In our previous work, the fire performance of seven upholstery materials combinations - including six barrier fabrics, one cover fabric and one flexible polyurethane foam - was assessed by (1) full-scale chair mock-up tests and (2) a newly developed bench
This report summarizes the experimental measurements submitted to the 2021 Condensed Phase MaCFP Workshop. Measurements from approximately 200 experiments were submitted by 16 unique institutions across 10 countries. This report contains: 1. Brief

The effectiveness and the failure mechanism of fire barriers in residential upholstered furniture were investigated by full-scale flaming tests on upholstered chair mock-ups. Six commercial fire barriers were tested in this study. Fire barriers were
The accuracy of the exhaust flow measurement contributes significantly to the uncertainty of calorimetry measurements for large fire testing. Less than ideal flow characteristics such as skewed velocity distributions are typical of these largescale flows
