Warning triangle platesfor motor vehiclesarecompulsory certification products in China,and its stability against wind is a required test item. However, due to the incomplete description of the test method in GB 19151—2003 Warning triangles for motor vehicle, there is no unified test method, equipment and test norms in automotive industry, result in test precisions are different and low, hence poor repeatability. In this paper, the test method and test equipments are conceived, test norms are developed, and the test scheme is verified by means of simulation. Finally, a test scheme with high precision and strong repeatability is obtained, and prototype equipments are fabricated, the scheme is verified for the test of stability against wind of waning triangle plate, therefore the validity for test method and test equipments are verified.
