详细介绍了全国钢标委组织相关单位开展的ISO 10113：2020标准验证工作。主要对人工、半自动和全自动3种测试方式的准确性和一致性进行验证，此外还对试样是否存在不均匀变形以及是否需要在计算公式中去除弹性应变等问题进行了试验。验证试验可以让相关人员更加清晰、全面地认识该标准中的一些关键条文，为下一步启动修订GB/T 5027—2016标准的工作打下良好基础，同时对推动国内塑性应变比(r值)测试技术的发展，促进国内装备水平的提高具有重要意义。

The verification work of ISO 10113:2020 standard organized by National Steel Standardization Committee was introduced in detail. The accuracy and consistency of manual, semi-automatic and automatic test methods were mainly verified. In addition, a series of tests were carried out on whether the specimen had uneven deformation and whether it was necessary to avoid elastic strain. The verification test could make the related personnel more clearly and comprehensively understand some key provisions in the standard, which layed a good foundation for the next step to start the revision of GB/T 5027—2016 standard. At the same time, it was of great significance to promote the development of domestic the plastic strain ration (r value) test technology and the improvement of domestic equipment level.
