本欧洲标准规定了在经受弯曲的GRC组合物的比例和失效极限下识别应力和变形性能的试验方法。它还用于为给定的GRC组合建立28天的常规强度与7天的强度之间的关系（参见prEN 1170-4）

This European Standard specifies a test method for identifying the stress and deformation performance, at the limit of proportionality and on failure, of a GRC composition subjected to bending. It is also used to establish, for a given composition of GRC, the relationship between the conventional strength at 28 days and the strength at 7 days (see prEN 1170-4)
