IEC60335-2-23手持式吹风机的电源线摇摆试验
标准的25.14: The force applied to the supply cord of appliances provided with a swivel connection is-20N, for cords having a nominal cross-sectional area exceeding 0.75mm2;
-10N, for other cords.
Hand-held appliances are additionally tested while mounted on an apparatus similar to that of Figure 8 with
the supply cord hanging vertically and loaded with a force of 10N. the oscillating part of the apparatus is
moved through an angle of 180 and back to the original position. the number of flexings is 10000, the rate
of flexing being 6 per min.
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 the appliance for storage.
NOTE 102 this test is not carried out on appliances incorporating a swivel connection.
困惑:看到102,对于旋转接电的手持式吹风机还要不要做摇摆试验?
看看名词解释:
3.103
swivel connection
means for connecting the supply cord so that the appliance can be rotated continuously
without twisting the cord.

首先感谢F老大的回复,可以确认吹风机是swivel connection,又是手持式,截面积为1.0mm2.
那么在25.14,是否还要做6/min,10000次的摇摆?
在25.15,拉力值从30N增加到60N.
在25.101,在1.25倍的额定电流下工作,绕主轴旋转,转速为50r/min,每20转改变一次转动方向,试验持续20000次。 kelvinwen 发表于 2015-6-5 10:23 http://bbs.angui.org/static/image/common/back.gif

单独就这句话来说:为什么还要去做?这么明白有争议?

可能不明白的是红色字体部分,前面说对这种旋转接电施加10N/20N作用力,NOTE又说这种不做。 kelvinwen 发表于 2015-6-5 13:50 static/image/common/back.gif

没有看前面的部分,如果是这样确实有点费解了。 fasten 发表于 2015-6-5 14:07 static/image/common/back.gif

看了某机构的测试报告,原来前半部分施加力按照60335-2-23的20N/10N,摇摆测试条件按照通标的90度,10000次,60次/min。这样也行?
