Evaluation methods 评估方法（5.5） For fracture toughness of the constituent products, reliance may be placed on properties for impact strength associated with materials and components used as constituent products provided these are given by reference to a European Technical Specification and inspection documents. If data for the constituent products are not available, fracture toughness may be assessed using Charpy impact tests carried out in accordance with EN 10045-1. For steel components provisions for evaluation of the test results are given in EN 1993-1-10 构件产品的断裂韧性可通过按其技术规范和检验资料给出的冲击强度评估， 如构件产品没有数据，应按EN10045-1进行冲击使用，结果应符合 EN1993-1-10规定
