On the International Temperature Scale of 1990 (ITS-90), Part II: Recommended Techniques for Comparisons, at the Highest Level of Accuracy, of Fixed-Point Cells Used for Contact Thermometry

January 1, 1999
Author(s)
Billy W. Mangum, P Bloembergen, M V. Chattle, B Fellmuth, P Marcarino, A I. Pokhodun
Techniques are recommended for comparisons, at the highest levels of accuracy, of fixed-point cells of the defining fixed points, excluding the vapour-pressure points, of the ITS-90, which are used for contact thermometry. The authors are the members of

Optical Coherence Tomography of Glass Reinforced Polymer Composites

Joy Dunkers, Richard~undefined~undefined~undefined~undefined~undefined Parnas, C G. Zimba, R C. Peterson, Kathleen M. Flynn, J G. Fujimoto, B E. Bouma
Optical coherence tomography (OCT) is a non-destructive and non-contact technique to image microstructure within scattering media. The application of OCT to highly scattering materials such as polymer composites is especially challenging. In this work, OCT

Optical Monitoring of Polypropylene Injection Molding

January 1, 1999
Author(s)
C L. Thomas, Anthony J. Bur
We have constructed an optical fiber sensor for monitoring injection molding and we have developed a model to describe sensor behavior. The sensor consists of a sapphire window at the end of a sleeved ejector pin into which an optical fiber is inserted

K J. Leuteritz
This past August 4-6 the first Federal Technical Standards Workshop was held in Washington, DC. The theme was Standards Management A World of Change and Opportunities. The purpose if the conference was to further the implementation of the National

Performance and Modeling of Heat Flux Sensors in Different Environments

January 1, 1999
Author(s)
David G. Holmberg, C A. Womeldorf
Heat flux measurement is not simple; care is required in selecting a suitable sensor for a given application. Surface substrate properties and the convective and radiative environment determine the choice of sensors. Mounting of the sensor, especially in
