7.3.1.17.1 Cine projectors shall be operated continuously with a film, the lamp being switched on.

电影放映机应带影片开灯连续运行。

7.3.1.17.2 Slide projectors shall be operated continuously without slides, the lamp being switched on. To determine the click rate N, see 7.2.3.3.

幻灯投影仪应无幻灯片开灯连续运行。按7.2.3.3确定喀呖声率N。

7.3.1.18 Milking machines shall be operated continuously without vacuum.

挤奶器应不抽真空连续运行。

7.3.1.19 Lawn mowers shall be operated continuously without load.

草坪割草机应空载连续运行。

7.3.1.20 Air conditioning equipment

空调设备

7.3.1.20.1 If the air temperature is controlled by changing the time interval of operation of the compressor motor used in the appliance, or the appliance has heating device(s) controlled by thermostat(s), measurements shall be made according to the same operating condition as in 7.3.4.14.

如果是通过改变器具内压缩机的运行间隔时间来控制空气的温度，或者器具有由温控器控制的加热装置，则测量应按7.3.4.14规定的相同运行条件进行。

7.3.1.20.2 If the appliance is a variable capacity type which has inverter circuit(s) that control(s) the revolution of the fan or compressor motor, measurements shall be made with the temperature controller setting at the lowest position when in cooling mode, and at the highest position when in heating mode.

如果器具是可变容量模式，其具有控制风扇或压缩机转速的电路，则在制冷模式下将温度控制器设定在最低温度下测量，在制热模式下将温度控制器设定在最高温度下测量。

7.3.1.20.3 The ambient temperature for testing the equipment by 7.3.1.20.1 and 7.3.1.20.2 shall be (15 ± 5) °C when the appliance is operating in heating mode, and (30 ± 5) °C when it is operating in cooling mode. If it is impractical to keep the ambient temperature within this range, another temperature is also permissible, provided that the equipment operates in a stable manner.

对于按7.3.1.20.1 和 7.3.1.20.2 测试的器具，当器具以制热模式运行时，环境温度应为(15 ± 5) °C ，当器具以制冷模式运行时，环境温度应为(30 ± 5) °C。如果保持该环境温度在此范围内是不实际的话，只要器具可以工作在稳定状态，其他的温度范围也是允许的。


The ambient temperature is defined at the temperature of the air flow to the indoor unit.

环境温度定义为流向室内机的空气的温度。

对于器具工作在稳定状态的其他温度范围，不明白这里为什么这么说，空调设备在室温下都可以工作在稳定状态的吗？为什么要强调制冷和制热模式下的温度限值？

7.3.1.20.4 If the appliance consists of indoor and outdoor units (split type), the length of connecting refrigerant pipe shall be 5 m ± 0,3 m and the pipe shall be shaped like a coil with a diameter of approximately 1 m. If the pipe length cannot be adjusted, it shall be longer than 4 m, but not longer than 8 m. For the measurement of disturbance power on the connecting leads between the two units, the leads shall be separated from the refrigerant pipe and extended to accommodate the clamp measurement. For all other measurements of disturbance power and disturbance voltage the connecting leads between the two units shall be routed along the refrigerant pipe. Where an earthing conductor is required, but not included in the mains lead, the earthing terminal of the outdoor unit shall be connected to the reference ground (see 5.2.1, 5.2.2 and 5.2.3). The artificial V-network shall be situated at a
distance of 0,8 m from the unit (either the indoor or outdoor unit) which is connected to the mains network. Depending on the maximum length of leads , other than the mains lead, the starting frequency for the terminal disturbance voltage measurement on these leads is given by the formula specified in sub-Clause 5.2.3.

如果器具包括室内机和室外机（分体式），制冷剂连接管的长度应为5 m ± 0,3 m ，并且将连接管绕成直径约为1m的圈。如果连接管的长度不能调节，它应长于4m但不长于8m。对于室内外连接线的骚扰功率测量，应将连接线与制冷管分开并延长以满足吸收钳测量。对于其他的骚扰功率和骚扰电压的测量，两部分的连接线应沿管子不知。当有不属于电源引线的接地线要求时，室外机的接地端子应连接到参考地上（见5.2.1, 5.2.2 和 5.2.3）。V型人工电源网络应放置距连接到电网的器具（室内机或室外机）0.8m的距离处。除了电源引线外，其他引线上端子骚扰电压测量起始频率由5.2.3规定的公式给出。

NOTE If no specific information about the length of auxiliary leads is given by the manufacturer, it can be assumed that their length is always greater than 2 m but less than 30 m.

注：如果制造商没有特别规定辅助引线的长度，则可以假定引线的长度总是大于2m，但是小于30m。

7.3.2 Electric tools

电动工具

该条款主要讲述的是电动工具的测试状态，根据实际情况，因为电动工具既要做的体积小，又需要较高的转速，因此电动工具中多用的是串激电机。

根据串激电机的结构，其中要换向器，碳刷的存在，因此串激电机的CE和DP都普遍较高。
