EN 60335-1/IEC 60335-1家用电器安规标准条款中19 Abnormal operation异常运行条件下的风险评估，是针对电子电路的设计和应用，使其在出现故障情况下，不引发电击、火灾、机械危险或危险的功能失常等不安全现象。 带电热元件的器具按19.2和19.3进行试验。 若器具带有控制装置，而这些控制装置在11章试验期间起限温作用，则这样的器具再要进行19.4的试验，并且适用时要进行19.5的试验。带有PTC电热元件的器具还要进行19.6的试验。 带有马达与电动机的器具，按适用情况进行19.7-19.10的试验。 带有电子电路的器具，按适用情况还要进行19.11和19.12的试验。 包含接触器或继电器的器具应通过19.14的测试 包含电压选择开关的器具要经过19.15的测试。

19.11.4 Appliances having a device with an off position obtained by electronic disconnection, or a device that can be placed in the stand-by mode, are subjected to the tests of 19.11.4.1 to 19.11.4.7. The tests are carried out with the appliance supplied at rated voltage, the device being set in the off position or in the stand-by mode. 19.11.4具有通过电子断开获得断开位置的装置或可处于待机状态的装置的器具，应通过19.11.4.1至19.11.4.7的测试。测试在额定电压下进行，设备设置在off位置或待机模式。

19.11.4.1 The appliance is subjected to electrostatic discharges in accordance with IEC 61000-4-2, test level 4 being applicable. Ten discharges having a positive polarity and ten discharges having a negative polarity are applied at each preselected point. 19.11.4.2 The appliance is subjected to radiated fields in accordance with IEC 61000-4-3, test level 3 being applicable. 19.11.4.3 The appliance is subjected to fast transient bursts in accordance with IEC 61000-4-4. Test level 3 with a repetition rate of 5 kHz is applicable for signal and control lines. Test level 4 with a repetition rate of 5 kHz is applicable for the power supply lines. The bursts are applied for 2 min with a positive polarity and for 2 min with a negative polarity. 19.11.4.4 The power supply terminals of the appliance are subjected to voltage surges in accordance with IEC 61000-4-5, five positive impulses and five negative impulses being applied at the selected points. Test level 3 is applicable for the line-to-line coupling mode, a generator having a source impedance of 2 Ω being used. Test level 4 is applicable for the line-to-earth coupling mode, a generator having a source impedance of 12 Ω being used. 19.11.4.5 The appliance is subjected to injected currents in accordance with IEC 61000-4-6, test level 3 being applicable. During the test, all frequencies between 0,15 MHz to 80 MHz are covered. 19.11.4.6 For appliances having a rated current not exceeding 16 A, the appliance is subjected to the class 3 voltage dips and interruptions in accordance with IEC 61000-4-11.The values specified in Table 1 and Table 2 of IEC 61000-4-11 are applied at zero crossing of the supply voltage. 19.11.4.7 The appliance is subjected to mains signals in accordance with IEC 61000-4-13, Table 11 with test level class 2 using the frequency steps according to Table 10. 19.11.4.8 The appliance is supplied at rated voltage and operated under normal operation. After approximately 60 s, the power supply voltage is reduced to a level such that the appliance ceases to respond to user inputs or parts controlled by the programmable component cease to operate, whichever occurs first. This value of supply voltage is recorded. The appliance is supplied at rated voltage and operated under normal operation. The voltage is then reduced to a value of approximately 10 % less than the recorded voltage. It is held at this value for approximately 60 s and then increased to rated voltage. The rate of decrease and increase of the power supply voltage is to be approximately 10 V/s.
