Intercomparison of laboratory radiance calibration standards

Several standards for radiometric calibration were measured repeatedly with a spectroradiometer in order to understand how they compared in accuracy and stability. The tested radiance standards included a NIST 1000 W bulb and Spectralon panel, two calibrated and stabilized integrating spheres, and a cavity blackbody. Results indicate good agreement between the blackbody and 1000 W bulb/Spectral...

Improvements in the Nist Calibration Service for Thermal Transfer Standards

We report on multiple improvements made in the calibration services offered for thermal converters and thermal transfer standards in the ac-dc Difference Standards and Measurement Techniques Project at NIST during the past year. The major improvement in this calibration is the increased efficiency made possible by the consolidation of three disparate calibration services – low voltage thermal t...

Calibration of Large Square Standards

In this paper the principle and device NME 90 for large square standards calibration is described. The self-calibration methods of measurement are used. They allow very low uncertainty of the square calibration with mathematical elimination of measuring column straightness deviations. The process of measurement is full automated and controlled by PC, which collects and evaluates measured data. ...

Calibration of dissipation factor standards

Working standards for dissipation factor (D) obtained by connecting a shielded three-tenninal capacitor in series with a shielded precision resistor have been developed for calibration purposes. Precision conductance boxes have been built for use with a single three-tenninallOOO pF gas capacitor standard to create dissipation factor standards having values from 2 x 10-5 to 1 X 10-2. The design ...
