This research was designed to help establish private household work standards useful to the home maintenance industry, and was part of a larger project concerned with standard izing time estimates and quality of tasks in household employment. Objectives were to derive a work time estimation technique for household dusting and to investigate the effects of selected factors on household dusting time. Eight workers dusted floor and nonfloor items twice in eight theoretical living rooms. Workers spent 67 percent of their time on basic work processes, 21 percent on facilitating processes, and 12 percent on pretasks and posttasks. Analysis of variance, split‐plot in time and space, was used to test hypotheses that there were no time differences for replications, workers, ornate and plain ornamentation, low and high density of floor items, low and high density of nonfloor items, and cleaning processes. Factors found statistically independent and additive were ornamentation, floor item den sity, and nonfloor item density. The derived work time estimation formula for dusting a laboratory living room was: estimated time = C + X 1 + X 2 + X 3 ; where C = a constant of 34 minutes mean time, X 1 = ornamentation factor, X 2 = floor item density factor, and X 3 = nonfloor item density factor. The derived estimates approximated actual average times for dusting.
