b) Assessment of disturbance level骚扰电平的评定
The click rate N, established as described above shall be used to calculate the click limit Lq using the formula given in 4.2.2.2.
用上述方法确定的喀呖声率N按4.2.2.2给出的公式来计算喀呖声率限值Lq。
The toaster shall be tested applying the calculated click limit Lq and assessed using the upper quartile method given in 7.4.2.6. The toaster shall be operated for 20 cycles without load at the setting specified in Item a). Each cycle shall comprise an operating period and a rest period, the latter having sufficient duration to ensure that the appliance is cooled to approximately room temperature at the beginning of the next cycle. Forced air cooling may be used.
用计算出的喀呖声限值Lq测试烤面包机时，按7.4.2.6给出的上四分法进行评定。烤面包机在a）项规定的设定和空载条件下运行20个周期。每个周期由运行周期和间歇周期组成。间歇周期足以满足在下一个周期开始之前使器具冷却到接近室温。可使用强迫通风冷却。
7.3.4.9.2 Other toasters shall be operated using the normal load. Each cycle shall consist of an operating period and a rest period, the latter having a duration of 30 s. The click rate N shall be determined at a setting at which the bread becomes golden-brown
其他烤面包机应在正常负载条件下运行。每个周期由工作周期和间歇周期组成，后者为30s，喀呖声率N应在面包烘烤成金黄色的设定上确定。
7.3.4.10 Ironing machines (ironing machines for table use, rotating ironing machines, ironing presses):the click rate N1 of the control device shall be determined with the heating surface being in the open position and the control devices at high temperature setting.
熨烫机器（台式熨烫机、旋转熨烫机、熨压机）；控制装置的喀呖声率N；应在加热表面在敞开位置，控制装置设定在最高温度位置的条件下确定。
The click rate N2 of the motor switch shall be determined when two damp hand-towels (approximately 1 m × 0,5 m) are ironed per minute.
电动机开关喀呖声率N；应在每分钟熨烫两个湿手巾（约1 m × 0,5 m）的情况下确定。
For fixing the click limit Lq the sum of the two click rates N = N1 + N2 has to be applied and the ironing machine shall be tested applying this limit and assessed using the upper quartile method given in 7.4.2.6 on both the control device and the motor switch.
为了确定喀呖声率限值Lq，必须应用两个喀呖声率的和N=N1+N2，且熨烫机用词限值进行测试并用7.4.2.6给出的上四分法对控制装置和电动机开关进行评定。
7.3.4.11 Irons shall be operated with the soleplate cooled using air, water or oil cooling. The click rate N is defined as the product of the factor 0,66 and the number of switching operations per minute for a duty-cycle of (50 ± 10) % of the control device operated at a high temperature setting.
电熨斗应在用空气、水货油冷却地板的条件下运行，喀呖声率N以控制装置在最高温度设定下(50 ± 10) % 的工作周期时每分钟的开挂操作数乘以因数0.66的积确定。
7.3.4.12 Vacuum packagers shall be operated with empty bags once per minute or according to the manufacturer's instruction for use.
真空包装机应在每分钟一个空包或制造商使用说明书规定的条件下运行。
7.3.4.13 Flexible electrical heating appliances (warming pads, electric blankets,bedwarmers, heating mattresses) shall be spread between two flexible covers (e.g. nonconducting mats), extending beyond the heating surface by at least 0,1 m. The thickness and
the heat conductivity shall be selected in such a way that the click rate N can be determined for a duty-cycle of (50 ± 10) % of the control device
柔性电热器具（保温垫、电热毯、热床垫）应铺在两层软覆盖物（如不传热织物）之间，覆盖面至少超出加热面0.1m。其厚度和导热性的选择应使得喀呖声率N能在控制装置(50 ± 10) %的工作周期时确定。
7.3.4.14 Room heaters (fan heaters, convectors, fluid-filled heaters as well as oil and gas burners and similar) shall be operated as in normal use.
房间加热器（风扇加热器、热交换器、液体加热器和油或气体燃烧器等类似器具）应在正常使用条件下运行。
