This study was carried out to investigate dropping shock of household electric appliances during mat erials handling. Microwave oven (18ℓ), TV (16˝) and washing machine (6.2kg) were singled out as the study items. From the results of dropping test by KS A 1026 (General Rules of Performance Testing for Packaged Freights), relative equations were gained as follow : y = 0.0863x + 10.032 for microwave oven , y = 0.136x + 7.85 for TV and y = 0.214x + 5.8 for washing machine (where y is G- fact or and x is Dropping height ). The maximum values of dropping shock during materials handling were measured t o be 11∼14G for microwave oven , 12∼15G for TV and 10∼12G for washing machine. The maximum shocks of microwave oven, TV and washing machine during materials handling were corresponding to dropping shocks of dropping height 45.98cm, 52.57cm and 28.97cm by KS A 1026.
