Metrological Traceability for Guarded-Hot-Plate Apparatus

May 9, 2013
Author(s)
Robert R. Zarr
An approach for establishing metrological traceability for measurement results from guarded-hot-plate apparatus consistent with policy at the National Institute of Standards and Technology (NIST) is presented. A brief example for initiating met-rological

Analysis of Thermal-Conductivity Measurement Data from International Comparison of National Laboratories

June 19, 2012
Author(s)
Bruno Hay, Robert R. Zarr, Clark Stacey, Leonel Lira Cortes, Ulf Hammerschmidt, Nikolay Sokolov, J.T. Zhang, Jean Remy Filtz
For the first time under the auspices of the Bureau International des Poids et Mesures (BIPM), seven national metrology institutes (NMIs) participated in an international interlaboratory comparison on thermal-conductivity measurements by the guarded hot

SRM 1450d, Fibrous-Glass Board, for Thermal Conductivity from 280 K to 340 K

August 1, 2011
Author(s)
Robert R. Zarr, Amanda C. Harris, John F. Roller, Stefan D. Leigh
Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450d, Fibrous Glass Board. The measurements have been conducted in accordance with a randomized full factorial

Assessing the Measurement Uncertainty of Thermophysical Properties

September 2, 2009
Author(s)
Robert R. Zarr
A generalized approach for the expression of measurement uncertainty consistent with current international practice is presented. The approach is applicable to all kinds of quantitative measurements including measurements of thermophysical properties. A

International Comparison on Thermal Conductivity Measurements of Insulating Materials by Guarded Hot Plate

September 2, 2009
Author(s)
Bruno Hay, Leonel Lira Cortes, Benoit Doucey, Jean Remy Filtz, Nikolay Sokolov, Clark Stacey, Robert R. Zarr, Jintao Zhang
An inter-laboratory comparison on thermal conductivity measurements of insulating materials is currently organized under the auspices of the Bureau International des Poids et Mesures (BIPM). Thermal conductivity measurements are carried out by seven
