Available in PDF, EPUB and Kindle. Book excerpt: An operational procedure for guarded hot box (GHB) testing has been developed in the Thermal Measurements Laboratory (TML) of the Construction Products Division of W. R. Grace and Co. The GHB operational procedures consisting of specimen preparation, "calibration", testing, data analysis, and reporting are presented in this report. These procedures follow the general guidelines given in ASTM Test for Steady-State Thermal Performance of Building Assemblies by Means of a Guarded Hot Box (C 236). In the specimen preparation procedure, material handling, specimen construction, specimen mounting into the specimen frame, and instrumentation placement and method of attachment are discussed in detail. The "calibration" procedure developed accounts for any variations in the thermal conductance of the metering box walls caused by design or construction. The experimentally determined setting for the thermopile electromotive force is controlled during testing so that the net heat flow through the metering box walls is negligible. The "calibration" procedure does not require knowledge of the thermal conductance of the specimen. A testing procedure is discussed that provides steady-state operation as defined by six steady 4-h periods of temperature and heat flow data within 1% of each other. The test data are analyzed and a GHB test report is generated by a computer software package. Examples of a typical GHB test report and a testing procedure data sheet are presented.

Download or read book A Detailed Verification Procedure for a Guarded Hot Box written by AG. Guy and published by . This book was released on 1987 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A verification procedure carried out for a particular guarded hot box facility is described. This relied on measurement of a uniform test specimen of known well-defined properties, these properties having been measured on an accredited guarded hot plate. An analysis of the various energy flows in the box is given, together with procedures for application of various correction measures required. These included a common zeroing of any out-of-balance flux through the metering box walls with that in the specimen across the metering box periphery. The effects of specimen mean temperature were included, and specimen thermal conductances and metering box thermal properties were determined using a linear regression approach. Resulting conductances were in good agreement with those obtained from the hot plate measurements.

Book excerpt: A questionnaire dealing with operating techniques and procedures of guarded and calibrated hot boxes was mailed to 14 hot box operators in the United States and Canada. Questions pertaining to testing capabilities, instrumentation, calibration specimens, steady-state criteria, etc., were asked. Responses from the 13 laboratories returning the survey are summarized in the paper. This information should be of interest to hot box operators, as well as prove helpful in future revisions of the guarded and calibrated hot box test methods.
