本欧洲标准规定了通过试管法测定结构发泡粘合剂薄膜或浆料粘合强度的试验方法。 该测试方法适用于通过压缩管剪切试样来测定粘合剂泡沫固化后的粘合强度。 它优选适用于高膨胀比，即根据EN 2667-3方法测量> 50％。

This European Standard defines the test method for determining the bond strength of structural foaming adhesive films or pastes by means of the tube test method. This test method is suitable for determining bond strength in relation to the density after curing of the adhesive foam by means of compressive tube shear specimens. It preferably applies to high expansion ratios, i.e.  50 % measured according to the method EN 2667-3.
