The invention provides an electric cable raw material incoming inspection process, and specifically relates to a rapid test method for the oxidation condition of a copper wire in a high temperature environment, wherein a natural ventilation type high-temperature oven is used. The rapid test method comprises: increasing the temperature of the natural ventilation type high-temperature oven to 200+/-2 DEGC, intercepting a copper wire with a length of not less than 5 m, placing the copper wire in the high-temperature oven, standing for 5 min, taking out the copper wire, and comparing the taken copper wire to RAL color card. According to the present invention, the rapid test method has characteristics of simple test device, short test time and simple test comparison method; and with the rapid test method, whether the copper wire is blackened, reddened, whitened and is subjected to other conditions after the copper wire passes through the continuous vulcanization pipe can be judged accordingto the oxidation condition of the copper wire after the test, and whether the copper wire is qualified can be rapidly judged by the inspection personnel.
