If an appliance has more than one rated voltage the multipliers 0,9 and 1,1 apply to the rated voltage that causes maximum disturbance.

如果器具有多于一个额定电压，则对应的引起最大骚扰的额定电压乘以0.9和1.1的系数。

For appliances with a frequency range of 50 Hz to 60 Hz, a test at about 160 kHz and at about 50 MHz shall be made using supply frequencies of 50 Hz and 60 Hz at the above determined supply voltage, in order to check whether the level of disturbance varies
considerably with the supply frequency; in which case, the measurements are to be made at the supply frequency which causes maximum disturbance.

如果器具频率范围为50Hz-60Hz，则在160kHz 和50MHz两个频点上进行测试，分别使用50Hz和60Hz频率，在上述已确定的供电电压下进行，以检查骚扰电平是否随着供电频率的变化而有明显地变化。在此情况下，则在引起最大骚扰的供电频率下进行测量。

7.1.4描述的是器具的电压和频率的选择，针对的现象有三种情况。

1.单个额定电压。
2.单个额定电压范围。
3.多个额定电压范围。

至于为什么会选择在160kHz和50MHz这个点乘以电压系数，这个问题，我一直也没有想明白，请明白的人出来解释下。谢谢。

7.1.5 Speed controls with a limited number of fixed positions are to be adjusted to approximately average and to maximum speed, the higher reading to be registered if there is no instruction to the contrary in this standard.

如果本部分中没有相反的说明，有极速度控制器应调节到平均值附近和最大速度，记录较高的读数。

Apparatus which incorporate electronic regulating controls shall have the controls adjusted for maximum disturbance in accordance with the procedure outlined in 7.2.6.1, in both frequency ranges 148,5 kHz to 30 MHz and 30 MHz to 1 000 MHz.

对于装有电子调节器的器具，控制器应按7.2.6.1的简述程序调节到最大骚扰，包括148.5kHz-30MHz和30MHz-1000MHz。

If the setting of continuously adjustable controls, which are not designed for frequent adjustment in normal use, has been pre-set, it shall not be adjusted during the test.

对于设计在正常使用不是经常调节的连续可调控器，如果已预先设定，则在试验期间不应调节。

针对速度控制的产品，例子很多，比如电吹风控制风量的I档，II档,III档等。吸尘器的高中低三档。食物搅拌机的高中低档位等。针对这些产品都是要测量中档和高档的骚扰水平的。

7.1.6 The ambient temperature shall lie within the range 15 °C to 35 °C.

环境温度应在15℃-35℃范围内。

7.2 Operating conditions for particular equipment and integrated parts

特殊设备和整体部件的运行条件。

7.2.1 Multifunction equipment
Multifunction equipment which is subjected simultaneously to different clauses of this standard and/or other standards shall be tested with each function operated in isolation, if this can be achieved without modifying the equipment internally. The equipment thus tested shall be deemed to have complied with the requirements of all clauses/standards when each function has satisfied the requirements of the relevant clause/standard.

同时适用本部分不同条款和/或其他标准的多功能设备，如果无需改动设备内部状况就能实现多功能的话，则应分别按每一功能进行单独试验。如果每一功能都满足有关条款/标准的要求，则认为试验设备室符合所有条款/标准的要求的。

For equipment for which it is not practical to test with each function operated in isolation, or where the isolation of a particular function would result in the equipment being unable to fulfil its primary function, the equipment shall be deemed to have complied only if it meets the provisions of each clause/standard with the necessary functions operative.

如果设备无法再每一种功能单独运行条件下测试，或某一功能的单独运行会导致设备不能满足其主要功能的要求，只要在必要的功能运行条件下满足每条款/标准的要求，就认为设备室符合要求的。

7.2.2 Battery operated appliances：电池供电类器具

The appliance shall be tested operating in each permitted mode and in accordance with the operating conditions given in 7.3.
器具应按每种允许的运行模式并在7.3规定的运行条件下进行测试。

In the frequency range 148,5 kHz to 30 MHz measurements on equipment with external batteries are made at the terminals of the connecting lead using a probe as described in 5.1.3 in series with the input of the measuring receiver. Equipment which is made to be held in the hand shall be connected to the artificial hand.

在148.5kHz-30MHz频段内，外接电池的器具应按5.1.3的规定用电压探头串联在接收机的输入端在连接引线的端子上进行测量，握在手中操作的器具应接上模拟手。


In the frequency range 30 MHz to 300 MHz measurement on equipment with external batteries are made as described in 6.3.2.2 with the current transformer of the clamp pointing toward the appliance.

在30MHz-300MHz频段内，外接电池的器具应按6.3.2.2的规定进行测量，吸收钳的电流互感器指向器具。
