Abstract

Abstract: The IEC 61591-2019 standard introduces the fluid dynamic efficiency test of range hoods. The test process is complex and is greatly affected by factors such as the test environment, equipment, and personnel operations. Therefore, the evaluation of laboratory measurement uncertainty is of great significance. The measurement uncertainty evaluation can improve the laboratory's detection ability and better evaluate the reliability of the test results, thereby reducing the probability of laboratory misjudgment. In the evaluation of measurement uncertainty, the measurement method and related influencing factors are analyzed, and improvements are made to the large influential factors, which can improve and increase the measurement accuracy.

Key words: Fluid dynamic efficiency, Uncertainty, Range hood
