Ergonomic Assessment of Countertop Height for the Design of a New Temperature Chamber Final Report
Units Under Tests (UUTs) will be serviced from a "countertop" that's located on the uppermost side of a new temperature chamber. An ergonomic assessment was performed to determine a working height that ensures the technicians will be able to reach the components inside the UUT in a safe and reliable manner. A review of the anthropometric data relative to elbow height was used to make this determination. Nominal work height was 41.89 inches for the population of interest, ranging from 5th to 95th percentile. After adjusting for the height and centerline dimensions of the UUT, the "countertop" was defined to be -- 26.0 inches. Next, a range of working heights was defined to accommodate the tasks involved with servicing the UUTs: from 38.0 to 45.8 inches. These values were compared with design guidelines from the general literature. The results were found to converge relatively well with the external references. 3
