小家电做IPX4摆管淋雨测试的摇摆范围是多少度？

622

角度为与垂直方向±180度淋水

应该是左右各90度，可以查 EN60335-1 CL15.1 测试5分钟

就是啊 应该是左右90度

2楼正解，3楼错解。

我看过GB的标准（具体哪个现在忘记了）是说+-180度，那应该可以理解为是360度淋雨了？IPX3和IPX4相差不是很大。

BS EN60335-1：2002 cl15.1
For IPX4 appliances, the horizontal centre line of the appliance is aligned with the pivot axis
of the oscillating tube. However, for appliances normally used on the floor or table, the
movement is limited to two times 90° from the vertical for a period of 5 min, the support being
placed at the level of the pivot axis of the oscillating tube.
If the instructions for wall-mounted appliances state that the appliance is to be placed close to
the floor level and specifies a distance, a board is placed under the appliance at that
distance. The dimensions of the board are 15 cm more than the horizontal projection of the
appliance.
Appliances normally fixed to a ceiling are mounted underneath a horizontal unperforated
support that is constructed to prevent water spraying onto its top surface. The pivot axis of the
oscillating tube is located at the same level as the underside of the support and aligned
centrally with the appliance. The spray is directed upwards.
For IPX4 appliances, the movement of the tube is limited to two times 90º from the vertical for
a period of 5 min.
标准写的很清楚角度应该是左右各90度。那个正负180是指的一个周期

limited to two times 90º from the vertical
离垂直方向2倍90度就是180度。
可以参考IEC 60529。那里不是说的2倍90度，而是直接说180度。其实做过这个测试的都知道是左右摇摆180度啦。
我说的是标准。
哪里有不负责任了啊，如有不妥，请指正。
要不换个说法，2楼正解。

对IPX4级器具，器具的水平中心线和振动管的轴心线平行。但若器具在通常使用中是放置在地板或桌面上使用，则支架放置到和振动管的轴心线相同的位置，且动作为从垂直方向转90°，以5min为周期，动作2次。
