7.2.3.1 Starters and speed control of sewing machines and dental drills. To determine the disturbance generated during starting and stopping the speed of the motor shall be increased to maximum speed over a 5 s period. For stopping, the control shall be reset quickly to its off position. To determine the click rate N, the period between two starts shall be 15 s.

缝纫机和牙钻的启动器和速度控制器,为了确定在启动和停止时产生的搜啊绕,启动时电动机的速度应在5s内增加到最大值。停止时控制器应迅速恢复到断开位置。为了确定喀呖声率,两次启动间隔为15s。

7.2.3.2 Starting switches in adding machines, calculating machines and cash registers shall be operated intermittently with at least 30 starts per minute. If 30 starts per minute cannot be attained, then intermittent operation with as many starts per minute as possible in practice shall be used.

加法器、计数器和点钞机的启动开关应以每分钟至少30次启动的间歇操作,如果不能达到每分钟30次的启动,则用实际尽可能达到的每分钟的启动数间歇运行。

7.2.3.3 Picture change devices of slide-projectors. To determine the click rate N, the device shall be operated with the lamp switched on and with four picture-changes per minute without slides.

幻灯投影仪的换片装置,为了确定喀呖声率N,装置应在开灯,以每分钟四次换片的速度(不用载片)运行。

7.2.4 Thermostats
Separate as well as incorporated thermostats for the control of electric room or water heaters, oil and gas burners and the like.

温控器指的是用于控制房间电热器、电热水器、油和气体燃烧器等器具的单独的或内置式温控器。

Thermostats for, or integrated in permanently installed room heating equipment intended for stationary use shall be allocated with a click rate N which is five times the click rate determined for a single, portable or removable room heater.

用于或装载预定放在固定位置使用且永久地安装的房间加热器内的温控器,其喀呖声率N为单个的,便携式的或可移式的房间加热器确定的喀呖声率的5倍。

The click rate N shall be determined for the maximum operating rate stated by the manufacturer or – if sold for or together with a heater or burner – for a duty-cycle of (50 ± 10) % of this heater or burner.

喀呖声率N应由制造商说明的最大运行速率确定,或者,如果与加热器或燃烧器一起出售,以加热器或燃烧器(50±10)%的工作周期确定。

这句话应该这样理解:因为温控器一般都是有动作温度的,在最大运行速率时,是指温控器最频繁的动作状态。如果与加热器一起出售,要找到某个状态,保证温控器的动作速率时最大速率的二分之一的状态下测试。我认为这样取的是个折中的测试状态,因为在EMC测试要求中,基本的前提是要求设备工作在典型的工作状态。取最大速率的的二分之一是比较实际的工作状态的。

The amplitude and duration of the disturbance shall be measured for the lowest rated current of the thermostat. For thermostats which have an acceleration resistor incorporated, the same measurements shall be performed in addition, without any separate heater connected.

骚扰幅度和骚扰持续时间应在温控器最小额定电流下测量。对于装有加速电阻器的温控器应在不接任何单独的加热器时进行同样的附加测量。

When, in practice, the thermostat may be used together with inductive loads (e.g. relay,contactor) all measurements shall be performed using such a device, having the highest coil inductance used in practice.

实践中,当温控器可能与感性负载(如继电器、接触器)一起使用时,所有测量应在用实际使用时有最大线圈电感的装置上进行。

In order to obtain a satisfactory measurement, it is essential that the contacts shall be operated for a sufficient number of times with a suitable load to ensure that the levels of disturbance are representative of those encountered in normal operation

为了得到令人满意的测量,用合适的负载使触点运行足够的次数是必要的,以确保能重现在正常运行中遇到的骚扰电平。
