This report documents an experimental program designed to investigate High Energy Arcing Fault (HEAF) phenomena for low-voltage metal enclosed switchgear containing aluminum conductors. This report covers full-scale laboratory experiments using

Report on High Energy Arcing Fault Experiments - Experimental Results from Open Box Enclosures

December 29, 2021
Author(s)
Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Christopher U. Brown, Wai Cheong Tam, Edward Hnetkovsky, Andre Thompson, Michael Selepak, Philip Deardorff, Kenneth Hamburger, Nicholas Melly, Kenneth Miller, Kenneth Armijo, Paul Clem, Alvaro Cruz-Cabrera, Byron Demosthenous, Austin Glover, Chris LaFleur, Raymond Martinez, James Taylor, Rana Weaver, Caroline Winters
This report documents an experimental program to investigate High Energy Arcing Fault (HEAF) phenomena. The experiments provide data to better characterize the arc to improve the prediction of arc energy emitted during a HEAF event. An open box allows for

This report documents an experimental program designed to investigate High Energy Arcing Fault (HEAF) phenomena for medium voltage electrical switchgear containing aluminum conductors. This report covers full-scale laboratory experiments using

Response Bias of Electrical Cable Coatings at Fire Conditions (REBECCA-FIRE)

June 9, 2020
Author(s)
Kevin B. McGrattan, Edward J. Hnetkovsky, Scott D. Bareham, Michael J. Selepak, Morgan Bruns
This report contains results of a multi-year experimental program called REBECCA-FIRE (Response Bias of Electrical Cable Coatings at Fire Conditions). Volume 2 of the three volume report focuses on the burning behavior of electrical cables that are

The Influence of Walls, Corners and Enclosures on Fire Plumes

March 19, 2018
Author(s)
Kevin B. McGrattan, Michael J. Selepak, Edward J. Hnetkovsky
This report documents two series of compartment fire experiments in which a natural gas burner is positioned in a corner, or against a wall, or inside a steel cabinet, to assess the effects on the plume and compartment temperatures. The measurements

Performance of Metal and Polymeric O Ring Seals during Beyond-Design-Basis Thermal Conditions

December 28, 2016
Author(s)
Jiann C. Yang, Edward J. Hnetkovsky, Doris L. Rinehart, Marco G. Fernandez, Felix Gonzalez, Joseph Borowsky
This paper summarizes the small scale thermal exposure test results of the performance of metallic and polymeric O- ring seals typically used in radioactive material transportation packages. Five different O-ring materials were evaluated: Inconel/silver

Alternate Substrates for Measuring Cigarette Ignition Propensity Using ASTM E 2187

August 11, 2016
Author(s)
Richard G. Gann, Edward J. Hnetkovsky, William F. Guthrie
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this Standard, a lit cigarette is placed on a substrate consisting of a number of layers of filter paper. The metric is whether the

Interlaboratory Study of an Alternate Substrate for Use in ASTM E 2187

August 11, 2016
Author(s)
Richard G. Gann, Morgan Bruns, Edward J. Hnetkovsky, William F. Guthrie
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this test method, a lit cigarette is laid on multiple layers of filter paper, and the observer identifies whether the cigarette burns

Investigation of Surrogate Smoldering Ignition Sources for Testing Soft Furnishings

March 1, 2015
Author(s)
Richard G. Gann, Morgan Bruns, Amanda Robbins, Edward J. Hnetkovsky, Michael Ladas
The introduction of cigarette ignition propensity standards has led to a reduction in the availability of high ignition propensity commercial cigarettes. Since high ignition propensity cigarettes are needed for soft furnishing flammability tests, a
