一直以来有这个测试,见60335-2-14//25.14
25.14 Addition: Hand-held blenders and hand-held mixers are also subjected to the following test while mounted on an apparatus similar to that of Figure 8. The supply cord is suspended vertically from the appliance and loaded so that a force of 10 N is applied. The oscillating part is moved through an angle of 180° and back to the initial position. The number of flexings is 2 000, the rate of flexing being six per minute. NOTE 101 The appliance is mounted so that the direction of flexing corresponds to that most likely to occur when the supply cord is wound around it for storage.
