Available in PDF, EPUB and Kindle. Book excerpt: The paper discusses some problems related to the guarded hot plate (GHP) and heat flow meter (HFM) apparatus that justify today research efforts and future research programs. For the GHP these include the problem of imbalance detection and its correlation with the metering area definition, the problem of gap width, and the problem of apparatus speed. Also discussed are the specimen-related issues involved in measurements on rigid, highly conductive materials and mass transfer within the specimen during tests.

This book was released on 1991 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The apparent thermal conductivity and thermal resistance of several building insulations were determined at the National Institute of Standards and Technology (NIST) using three apparatus. Reference values were determined with NIST's 1-metre Line-Heat-Source Guarded Hot Plate (GHP). The other two apparatus were heat-flow-meter (HFM) apparatus calibrated with a Standard Reference Material of fibrous-glass board (138 kg/m3). The apparatus -- NIST's 1-metre GHP; the 610 mm HFM; and the 305 mm HFM -- were operated at a mean temperature of 24°C and temperature difference of 22°C across the thickness of the specimen. Measurements of thermal conductivity were determined for individual specimens nominally 25 mm thick, covering a range of thermal conductivity from 0.02 to 0.16 W/(m•K). The thermal resistance of thick specimens (1 to 7 m2•K/W) of cellular plastic, fibrous and loose-fill insulation was also determined. Deviations from reference values of the GHP were calculated for the HFM apparatus. For the 610 mm HFM, the majority of deviations were within ±3% of the GHP. Substantial improvement was achieved by calibrating the 305 mm HFM as a function of thickness; however, deviations ranged from +1.5 to +9.2% from the GHP. The apparatus, test procedure, and analysis of the deviations are described in the paper.

Rennex and published by . This book was released on 1985 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A summary is given of the error analysis of the National Bureau of Standards (NBS) 1016-mm guarded hot plate (GHP) apparatus, with emphasis given to new ideas or techniques. The report discusses the following items: a brief introduction to the principle of measurement, a rationale for the method of summing of uncertainties, a list of individual uncertainties, a description of the innovative plate temperature control method, and a derivation of the error due to systematic uncertainty for the heat flow meter apparatus.

Download or read book Historical Review of the Metered Section Area for the Guarded-Hot-Plate Method written by Robert R. Zarr and published by . This book was released on 2018 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of an extensive literature review and investigation of the metered section area for the guarded-hot-plate method, standardized as ASTM C177, Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means of the Guarded-Hot-Plate Apparatus , are presented. The guarded-hot-plate apparatus is a primary linear-heat-flow method generally used to determine the thermal conductivity of insulating and building materials. The review examined technical publications from 1885 to 1990 and identified 31 papers of interest. Historical versions of ASTM C177 were also researched as well as test methods from other standard development organizations. The investigation revealed that, over the past 100 years, researchers have independently developed two main approaches for the computation of the metered section area. An assessment of the calculation techniques is presented for round plates with diameters from 250 to 1,000 mm, a guard-to-meter aspect ratio of 2, and guard gap widths of 14 mm. The gap effects are not negligible because large gaps (4 mm) on small plates (250 mm) can lead to errors of 10 % or more on the computation of the metered section area, ultimately affecting the uncertainty of the test results of the guarded-hot-plate method. The results of this study are applicable to other thermal conductivity test methods that employ a primary thermal guard to promote 1-D heat flow.
