规定方法的原理是以一种可被视为交变应力与静应力（即平均应力）叠加的方式对试样施加循环应力。确定给定平均应力和应力幅度下试样失效时的循环次数。这些值用于建立SN曲线，从而可以估计与接头疲劳抗力有关的置信区。疲劳性能是试样几何形状的函数。结果与粘合剂的固有特性不符，不能用于设计目的。

The principle of the method specified is cyclically stressing the specimen in a way that may be regarded as the superposition of an alternating stress on a static stress which is the mean stress. The number of cycles at failure of the specimen for a given mean stress and stress amplitude is determined. These values are used to establish SN curves which then permit the estimation of the confidence zone concerning the fatigue resistance of a joint. The fatigue properties are a function of the specimen geometry. The results do not correspond to intrinsic properties of the adhesive and cannot be used for design purposes.
