By improving testing principle and testing tongs in QJ3074--1998, ,the testing accuracy of four probe method for electric resistivity of wire materials was raised and the testing scope was widened. Through the experiments of the effect of sample length and testing conditions on the testing results ,the electric resistivity of various carbon fibers is characterized systematically and that laid an important technical foundation for establishing standard of the testing method of electric resistivity for carbon fibers.
