For testing switch disturbance or semiconductor control disturbance see 7.2.3.1 or 7.2.6.1..
对于测试开关或半导体控制器的骚扰按照7.2.3.1 或7.2.6.1..
7.3.3.2 Saws and knives shall be operated continuously without load.
锯和刀应空载连续运行。
7.3.3.3 Electrocardiograms and similar recorders shall be operated continuously with a tape or paper.
心电图和类似用途记录仪应带记录带或记录纸连续运行。
7.3.3.4 Pumps shall be operated continuously with a liquid.

7.3.4 Electrical heating appliances
电热器具
Before making measurements the appliances shall reach steady-state conditions. The click rate N shall be determined for a duty-cycle of (50 ± 10) % of the control device, unless otherwise specified. If the duty-cycle of (50 ± 10) % cannot be reached, the highest possible duty-cycle shall be applied instead.
在测量之前器具应达到稳定运行状态。除非有其他规定，喀呖声率N应以控制装置的 (50 ± 10) %的工作周期确定，如果不能达到 (50 ± 10) %的工作周期，应用最大可能的工作周期替代。
7.3.4.1 Hob elements of hobs and heating elements of hotplates, controlled by thermostats or by energy regulators are operated with a duty cycle (50 ± 10) % of the control device. An aluminium pan filled with water is placed on the element. The click rate N is half of the number of switching operations per minute. If a hob or hotplate contains more than one element, the click rate shall be measured and evaluated for each individual element in turn.
由温控器或能量调节装置所控制的烤架和扁平烤盘的加热元件，应在控制装置的(50 ± 10) %的工作周期下运行。将装满水的铝盘放在加热装置上。喀呖声率N是每分钟开关操作数的一半。如果烤架或扁平烤盘包含一个以上的加热元件，则喀呖声率在每一个单独的加热元件运行时轮流进行测量和评定。
7.3.4.2 Cooking pans, table-type roasters, deep-fat fryers shall be operated as in normal use. Unless a minimum oil level is specified the quantity of oil above the highest point of the heating surface shall be:
电煮平底锅、台式烤肉箱、深油炸锅应在正常使用下运行。除非规定最低油位，否则在加热面最高点以上的油位为：
– about 30 mm for cooking pans, 电煮平底锅约30mm
– about 10 mm table-type roasters, 台式烤肉箱约为10mm
– about 10 mm for deep-fat fryers. 深油炸锅约为10mm
7.3.4.3 Feed boilers, water boilers, kettles, coffee makers, milk boilers, feeding-bottle heaters, glue pots, sterilizers, wash boilers, shall be operated half-filled with water and without lid. Immersion heaters shall be operated fully submerged. The click rate N shall be
determined with a medium setting (60 °C) of a variable control device having a range between 20 °C and 100 °C or with the fixed setting of a fixed control device.
供水锅炉、电开水壶、水壶、咖啡机、热奶器、奶瓶加热器、煮胶锅、灭菌器、洗涤锅炉应在灌半壶水不带盖时运行，浸入式热水器应完全浸入水中运行。应以控制范围在20℃-100℃之间的可变控制器的中间设定（60℃）或固定控制装置的固定设定来确定喀呖声率N。
7.3.4.4 Instantaneous water heaters shall be operated in usual position of use with the water flow set at half of the maximum flow rate. The click rate N shall be determined with the highest setting of any control device fitted.
快热式热水器应在正常使用位置进行，水流设定为最大水流的一半。应将所有安装的控制装置设为最高值来确定喀呖声率N。
