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.
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.
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.
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。
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。
