本欧洲标准规定了一种用于确定砌体中水平卧床接缝的平面剪切强度的方法，该方法采用使用垂直于床接头施加载荷的双剪切试样进行试验的片材防潮层材料。给出了样品的制备，试验前所需的调理，试验机，试验方法，计算方法和试验报告的内容

This European Standard specifies a method for determining the in plane shear strength of horizontal bed joints in masonry incorporating sheet damp proof course material using a specimen tested in double shear with load applied perpendicular to the bed joints. Guidance is given on the preparation of the specimens, the conditioning required before testing, the testing machine, the method of test, the method of calculation and the contents of the test report.
