Vacuum Processing Technique for Development of Primary Standard Blackbodies

June 1, 1999

Author(s)

Magdalena Navarro, Sally Bruce, B. Carol Johnson, A V. Murthy, Robert D. Saunders

Blackbody sources with nearly unity emittance that are in equilibrium with a pure freezing metal such as gold, silver, or copper are used as primary standard sources in the International Temperature Scale of 1990 (ITS-90). Recently, a facility using radio

New Photometric Calibration Programs at the National Institute of Standards and Technology

October 1, 1998

Author(s)

Yoshihiro Ohno, Magdalena Navarro

The National Institute of Standards and Technology (NIST) candela is maintained via standard photometers which have shown long-term stability better than 0.1% per year. The detector-based method has allowed us to reduce the uncertainties of calibrations

Reduction of Hydrogen Cyanide Concentrations and Acute Inhalation Toxicity From Flexible Polyurethane Foam Combustion Products by the Addition of Copper Compounds. Part 4. Effects of Combustion Conditions and Scaling on the Generation of Hydrogen cyanide

December 1, 1992

Author(s)

Barbara C. Levin, E Braun, M Paabo, Richard H. Harris Jr., Magdalena Navarro

Two full-scale protocols (A & B) were tested to determine the efficacy of cuprous oxide (Cu2O) in reducing the concentrations of hydrogen cyanide (HCN) from flexible polyurethane foams (FPU) when thermally decomposed under "realistic" room conditions. In

Reevaluation of Experimental Cigarettes Used in the Cigarette Safety Act of 1984. Report of Test (Report of Test FR 3984)

May 1, 1991

Author(s)

Richard H. Harris Jr., Magdalena Navarro, Richard G. Gann, K Eberhardt

Experimental cigarettes which had been stored for several years in freezers were reevaluated on mockups constructed from the same materials in the original study and statistically analyzed for differences in their ignition propensity.
