Oil resistance test method and oil resistance test apparatus

An oil resistance test method for an electronic device (100) is provided. At least one type of resin material is provided on at least a portion of an outer surface of the electronic device (100). The oil resistance test method includes: setting a test temperature; and immersing the electronic device in a water-soluble cutting oil (15) in an atmosphere of the set test temperature. This cutting oil contains a mineral oil (15) and a surfactant, and exhibits a milky-white appearance when diluted with water. The oil resistance test method further includes: determining, based on an electrical characteristic of the electronic device (100), whether or not the electronic device (100) has been degraded by the cutting oil (15); and estimating, based on a total immersion time of the electronic device (100) in the cutting oil (15) until degradation of the electronic device (100) is detected, a life of oil resistance of the electronic device (100). 本发明提供种电子机器的耐油性试验方法。电子机器(100)的外表面的至少部分设置有至少种树脂材料。耐油性试验方法具备：设定试验温度的步骤，以及在设定的试
