Development of High Throughput Methods for Polymer Flammability Property Characterization

February 19, 2017
Author(s)
Jeffrey W. Gilman, Rick D. Davis, John R. Shields, D Wentz, L D. Brassell, A B. Morgan, R Lyon, J E. Zanetto
Recently we have developed several new high throughput (HT) methods to quantitatively evaluate the flammability of flame retarded (FR) polymers. The most recent results are due to the efforts of the High Throughput Methods for Materials Flammability

Dielectric Spectroscopy During Extrusion Processing of Polyamide-6 Nanocomposites

February 19, 2017
Author(s)
Rick D. Davis, Anthony J. Bur, Jeffrey W. Gilman, Young Jong Lee, P R. Start
During extrusion processing dielectric spectroscopy was conducted on polyamide-6 (PA6) and organoclay/polyamide-6 nanocomposites. Off-line curve fitting of the on-line dielectric data generated dielectric dispersion parameters that appear sensitive to

Effect of Carbon Nanofiber Network Formation on Flammability of Flexible Polyurethane Foams

Author(s)
Mauro Zammarano, Roland H. Kraemer, Richard H. Harris Jr., Thomas J. Ohlemiller, John R. Shields, Sameer Rahatekar, Jeffrey W. Gilman
Polyurethane flexible foams (PUFs) are used extensively as upholstery and bedding materials. Untreated PUFs are prone to rapid fire growth due to their low density and thermal conductivity. Furthermore, the low viscosity of the decomposition products

Energy Escalation Rate Calculator (EERC1.0-03)

February 19, 2017
Author(s)
L I. Schultz, S Fuller
The Energy Escalation Rate Calculator (EERC) computes an average annual escalation rate for fuel prices, based on the annual energy price forecasts of the Energy Information Administration (EIA) of the U.S. Department of Energy (DOE). This rate is used to

Factors Affecting the Service Life of Seams of EPDM Roof Membranes

February 19, 2017
Author(s)
Walter J. Rossiter Jr, Jonathan W. Martin
A quarter century ago, a revolution occurred in the U.S. low-sloped roofing industry with the introduction of a number of new membrane products including elastomeric and thermoplastic polymeric membranes and polymer-modified bituminous membranes. Today

Federal Investigation of the Evacuation of the World Trade Center on September 11, 2001

February 19, 2017
Author(s)
Jason D. Averill, Dennis S. Mileti, Richard D. Peacock, Erica D. Kuligowski, N Groner, Guylene Proulx, H Nelson
This paper presents the findings of the NIST World Trade Center Investigation describing the occupant evacuation of WTC 1 and WTC 2 on September 11, 2001. The egress system, including stairwells and elevators, is described along with the evacuation

Final Report for:EPA: LAG No. DW-13-93903501-0 Expanding a Tool for Predicting Chloride Diffusivity in Concrete So It Can Be Used by Manufacturers to Evaluate the Durability of Concrete Made With Blended Cements. Part I: Characterizing Blended Cement...

X Feng, Edward Garboczi, Jeffrey W. Bullard, Kenneth A. Snyder, Paul E. Stutzman, T Mason
This report summarizes a project that dealt with the characterization of a fly ash and fly-ash blended cement material, so that these could be incorporated into the Virtual Cement and Concrete Testing Laboratory (VCCTL) software. The information generated

Fire as a Building Load

February 19, 2017
Author(s)
Richard W. Bukowski
The concept of designing buildings to resist loads is fundamental to the design and regulatory process. Fire has traditionally been addressed differently because fires are difficult to describe in the same way as other building loads. This paper proposes a

Fire Endurance Testing of Floor Systems Effects of Scale and Restraint

February 19, 2017
Author(s)
John L. Gross
Three standard fire resistance tests (ASTM E 119) were conducted on a composite floor system to study the effects of 1) test restraint conditions, and 2) scale of the test. Two full-scale tests, 35 ft (10.7 m) span, and one half-scale test, 17 ft (5.2 m)
