5.2.2 Disposition of appliances under test and their connection to the artificial mains V-network

受试器具的布置和V型人工电源网络的连接

5.2.2.1 Appliances normally operated without an earth connection and not held in the hand

The appliance shall be placed 0,4 m above an earthed conducting surface of at least 2 m × 2 m in size and at a distance of 0,8 m from the artificial mains V-network and shall be kept at least 0,8 m from any other earthed conducting surface. If the measurements are made
in a screened enclosure, the distance of 0,4 m may be referred to one of the walls of the enclosure.

5.2.2.1 通常不接地的非手持式器具

器具应放置在尺寸至少为2m*2m的接地导电平面上方0.4m，与V型人工电源网络之间的距离为0.8m，并且与其他接地导电平面至少保持0.8m的距离，如果测量在屏蔽室内进行0.4m的距离可以知道屏蔽室的任一墙壁。

上面的描述是针对非落地式的II类器具。

关于I、II、III类器具，是安规中的一个非常重要的概念，是从器具的安全角度了分类的，具体的解释大家可以参考GB4706.1中的第三章的定义解释。

如果从插头上区分。I类就带有地线的，三个插头的；II类就是两个插头的，没有接地线。

Equipment that, according to its design and/or weight, usually stands on the floor while in use (so-called floor standing equipment) is subject to the same provisions as above.

由于设计和/或自重的原因，使用是经常放在地上的器具（既落地式器具）应同样满足上述规定。
但是（也要考虑到以下的布置）
However,
– the equipment shall be placed on a horizontal metal ground plane (the reference ground plane), but isolated from it by a non-metallic support (such as a pallet) of 0,1 m ± 25 % in height;

器具应放置在水平金属接地平板上（参考接地平板），但用高度为0.1（1±25%）m非金属支撑隔开。

– the lead shall be led downward along the EUT to the level of the non-metallic support and be led horizontally to the artificial V-network;
引线应沿着受试器具向下至非金属支撑面高度水平连接到V型人工电源网络。

– the artificial V-network shall be bonded to the reference ground plane (see CISPR 16-2-1);
V型人工电源网络应与参考接地平板有良好的接地。

– the reference ground plane shall extend at least 0,5 m beyond the boundaries of the EUT and have minimum dimensions of 2 m by 2 m.
参考接地平板至少超出收拾器具边缘0.5m，尺寸至少为2m*2m.

在家电里面，有黑电和白电的说法，其实二者没有严格的界定，黑白是从颜色的来区分的，像洗衣机、冰箱、空调等大件家电，主要颜色是白色，称为白电；像电吹风、直发器、卷发棒、拔毛器等主要颜色是黑色的，称为黑电。

上述的条款，其实主要就是对落地式和非落地式家电的EUT布置和与V型人工电源网络连接的要求。理解这个条款是，关键是要对EUT做出区分，该把EUT划分为落地式，还是非落地式设备。这点很重要。

5.2.2.2 Handheld appliances which are normally operated without an earth connection

通常不接地的手持式器具。

对于该条款，大家可以理解为II类手持式器具。在家电中大家最常见的就是电吹风。

Measurements shall first be made in accordance with 5.2.2.1.

受试器具首先按照5.2.2.1的布置进行测量。

Additional measurements shall then be made using the artificial hand described in 5.1.4.

其次按照5.1.4规定使用模拟手进行测量。

这里出现了模拟手，在该标准中，模拟手的使用对象是手持式II类器具。在接下来的条款中，详细说明了模拟手的现场布置。

The general principle to be followed in the application of the artificial hand is that the metal foil shall be wrapped around all handles, both fixed and detachable, supplied with the appliance and the terminal M shall additionally be connected to any exposed non-rotating
metalwork as specified in 5.2.2.2.2 to 5.2.2.2.4.

使用模拟手的一般原则是用金属箔包裹器具附带的所有手柄，包括固定式和可拆卸式手柄，且M端应同时连接到按照5.2.2.2.2到5.2.2.2.4规定的裸露的、非旋转的金属件上。

Metalwork which is covered with paint or lacquer is considered as exposed metalwork and shall be directly connected to the terminal M of the RC element。

表面覆盖涂料或者油漆的金属件被认为是裸露金属件，应直接与RC原件的M端相连。

The artificial hand shall be applied only on the handles and grips and those parts of the appliance specified as such by the manufacturer. Failing the manufacturer's specification, the artificial hand shall be applied in the following way。

模拟手的应用仅在手柄和把手以及制造商规定的那些部分，如果没有制造商的说明，模拟手应按下面的条款应用。
