The invention provides a method and a device for checking the performance of an insulating paperboard. The method comprises the following steps: determining a test boundary threshold value and an acceptable reject ratio of a to-be-checked insulating paperboard; carrying out an insulating property test on the batch of insulating paperboards to be tested, and fitting test data to obtain a failure probability function; and judging a test result in the insulation performance test on the basis of the threshold value and the acceptable reject ratio of the to-be-detected insulation paperboard. In the test electrode design process, the applicability of batch test, the electric field uniformity of a test device and the equivalence of a test electric field and an actual electric field are considered at the same time, so that the test result is more accurate, and the result deviation caused by local electric field distortion of the test device is avoided; test results are judged by adopting a statistical analysis method, and the method has relatively strong adaptability to the characteristics of high oil paper insulation discharge dispersity and more batch test data; and batch testing can be conveniently carried out, and the testing efficiency is greatly improved.
