The second workshop on heat flux gauge calibration was
organized to share the results of an effort to expand
competence at NIST, and to examine the recommendations
made at a previous workshop on heat flux gauge
calibration. Over 40 attendees were drawn from U.S.
industry, academia, and government organizations.
Representatives of a spectrum of industries that rely
upon accurate measurement of heat flux described their
applications and calibration needs. Presentations were
made by Pratt & Whitney, Arnold Engineering Development
Center, Ktech Corporation, Lucent Technologies, and
Boeing Commercial Airplane Company. A panel of heat
flux gauge manufacturers that included representatives
of Vatell Corporation, Medtherm Corporation, Concept
Engineering, and RdF Corporation gave the perspective
from their industry. The efforts being undertaken in
Europe to standardize heat flux calibration methods for
fire safety standards were also discussed. Explanations
and tours of NIST heat flux calibration laboratories
were conducted by NIST staff. Discussions among all
participants were organized around special
considerations and calibration needs of heat flux
measurement devices for three different situations: (1)
convection dominated, moderate temperature, quasi-steady
environments with size and cost as major constraints;
(2) convection dominated, high temperature, transient
environments with small size and accuracy highly
desirable; and (3) radiation dominated with high flux
levels, with applications constrained by regulations.
Recommendations for future actions and the parties
responsible are given at the end of this report.
