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.
