Author(s)
Ranbir Singh, Kenneth G. Irvine, D C. Capell, James Richmond, David W. Berning, Allen R. Hefner Jr., John W. Palmour
This paper reports the design, fabrication, and high temperature characteristics of 1 mm 2, 4 mm 2, and 9 mm 2 4H-SiC rectifiers with 6 kV, 5 kV, and 10 kV blocking voltage respectively. These results were obtained from two lots in an effort to increase

Size Distribution and Light Scattering Properties of Test Smokes (NIST SP 965)

February 1, 2001
Author(s)
D W. Weinert, Thomas Cleary, George W. Mulholland
Measurements of particles size distributions and optical properties of smoke detector test smokes may yield a better understanding of existing detector designs and facilitate design improvements; NIST is making such measurements now on smokes produced in

Evaluation of Fire Properties of Generic Gypsum Board Products.

August 1, 1977
Author(s)
James R. Lawson
An evaluation of the fire properties of generic gypsum board products was made in order to obtain a better understanding of the material's reaction to a fire environment. These gypsum board products are typically used in wall and ceiling assemblies
