The Roles of Standard Cigarettes in Assuring the Ignition Resistance of Soft Furnishings

November 18, 2020
Author(s)
Richard G. Gann, Ickchan Kim, Steven P. Lund, William F. Guthrie, Rick D. Davis
Regulations for cigarette ignition resistance (CIR) of soft furnishings (beds and upholstered furniture) and less fire-prone cigarettes have contributed substantially to the decrease in losses from cigarette-initiated fires over time. Two Standard

A new material has been certified to become Standard Reference Material (SRM) 2806b - Medium Test Dust in Hydraulic Fluid. SRM 2806b consists of a trace polydisperse, irregularly shaped mineral dust particles suspended in hydraulic fluid. The certified

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

Process Optimization for Lattice-Selective Wet Etching of Crystalline Silicon Structures

March 9, 2016
Author(s)
Ronald G. Dixson, William F. Guthrie, Richard A. Allen, Ndubuisi G. Orji, Michael W. Cresswell, Christine E. Murabito
Lattice-selective etching of silicon is used in a number of applications, but it is particularly valuable in those for which the lattice-defined sidewall angle can be beneficial to the functional goals. A relatively small but important niche application is

Fiber Bragg Grating Based Thermometry

October 1, 2015
Author(s)
Zeeshan Ahmed, Bernard J. Filla, William F. Guthrie, John S. Quintavalle
In recent years there has been considerable interest in developing photonic temperature sensors such as the Fiber Bragg gratings (FBG) as an alternative to resistance thermometry. In this study we examine the thermal response of FBGs over the temperature

Re-Certification of SRM 2492: Bingham Paste Mixture for Rheological Measurements

August 25, 2015
Author(s)
Chiara F. Ferraris, Alex Olivas, William F. Guthrie, Blaza Toman
Rheological measurements are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating [1]. Usually, an angular velocity is imposed on the fluid (through the rotating

Use of Single Particle Inductively Coupled Plasma Mass Spectrometry to Characterize a New Silver Nanoparticle Reference Material

June 11, 2014
Author(s)
Karen E. Murphy, Jingyu Liu, William F. Guthrie, Justin M. Gorham, John E. Bonevich, Andrew J. Allen, Michael R. Winchester, Vincent A. Hackley, Robert MacCuspie
In this study we use inductively coupled plasma mass spectrometry operated in single particle mode (spICP-MS) to simultaneously characterize the size distribution and dissolved silver fraction of a new silver nanoparticle (AgNP) candidate reference

Bilateral NMI Comparison of Guarded-Hot-Plate Apparatus

April 27, 2014
Author(s)
Alain Koenen, Robert R. Zarr, William F. Guthrie
Two national metrology laboratories (NMI) have conducted an international interlaboratory comparison on thermal conductivity on two thermal insulation reference materials. The Laboratoire national de métrologie et d'Essais (LNE) from France and the

Certification of Total Arsenic in Blood and Urine Standard Reference Materials by Radiochemical Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectrometry

March 1, 2014
Author(s)
Rick L. Paul, William C. Davis, Karen E. Murphy, Colleen E. Bryan Sallee, Lee L. Yu, William F. Guthrie, Dennis D. Leber, Thomas W. Vetter
A newly developed procedure for determination of arsenic by radiochemical neutron activation analysis was used to measure arsenic in SRM 955c Toxic Elements in Caprine Blood and SRM 2668 Toxic Elements in Frozen Human Urine for the purpose of providing
