Journal ArticleDOI
A slug calorimeter for evaluating the thermal performance of fire resistive materials
TL;DR: In this paper, the authors used a slug calorimeter to evaluate the thermal performance of fire resistive materials (FRMs) by placing the slug at the bottom of an electrically heated box furnace and monitoring the temperatures of the metal slug and FRM surfaces during multiple heating and cooling cycles.

Assessment of Uncertainties for the Nist 1016 MM Guarded-Hot-Plate Apparatus: Extended Analysis for Low-Density Fibrous-Glass Thermal Insulation
TL;DR: For the NIST 1016 mm Guarded-Hot-Plate apparatus, considerable improvement may be realized by developing better control strategies for guarding that include better measurement techniques for the guard gap thermopile voltage and the temperature sensors.
Journal ArticleDOI
Retrospective Analysis of NIST Standard Reference Material 1450, Fibrous Glass Board, for Thermal Insulation Measurements.
TL;DR: Thermal conductivity data acquired previously for the establishment of Standard Reference Material (SRM) 1450, Fibrous Glass Board, as well as subsequent renewals 1450a,1450b, 1450c, and 1450d, are re-analyzed collectively and as individual data sets.
Book ChapterDOI
A Dynamic Test Method for Determining Transfer Function Coefficients for a Wall Specimen Using a Calibrated Hot Box
TL;DR: In this paper, a wall specimen is installed between the climatic and metering chambers of a calibrated hot box (CHB), and the temperature in the CHB is quickly ramped from an initial to a final temperature level in a linear manner.
Journal ArticleDOI
Calibration of the NBS Calibrated Hot Box
TL;DR: In this paper, a series of calibration tests were conducted in the laboratory in order to determine the overall experimental error and uncertainty for the NBS calibrated hot box, where 10 cm (4 in.) and 20 cm (8 in.) wall specimens having independently measured thermal resistances were installed in a support frame and sandwiched between the metering and climatic chambers.
