Abstract

For a specific test method, ruggedness experiments are used to determine experimental conditions that significantly influence the measurement results and to determine how closely these conditions must be controlled to reduce their influence. In this paper, the results of ruggedness experiments using hot box test methods (ASTM C 1199, C 1363, and ISO 12567-1) that are used for the thermal transmittance measurement of fenestration systems are presented. A general procedure of ruggedness evaluations was conducted on the University of Massachusetts Research Calibrated Hot Box. Using ASTM E 1169, a Plackett-Burman (P-B) design with eight experiments was used to investigate the effects of the seven most important experimental conditions. Two experimental conditions, the weather side and metering side fan speeds, were found to have the most significant effects on fenestration systems thermal transmittance measurement results.
