Abstract: The revision process of ISO 11531:2022 international standard is introduced. According to the test steps specified in the international standard, the applicability evaluation tests of thin steel plate and aluminum alloy plate samples are carried out respectively, and the earing results are obtained and the earing rate is calculated. The test cases can provide technical support for the testers to understand and use the international standard, and also contribute to the development and testing of high-strength metal sheets and strips, and improved the evaluation level of the process performance of thin sheets and strips.
