IEC 61547的本部分描述了一种客观光闪烁计，可用于以下目的: -测量所有照明设备的固有性能，无需施加照度闪烁方面的电压波动；在测量过程中，照明设备配有稳定的电源；-测试照明设备在照度闪烁方面对交流电源（无意）电压波动干扰的抗扰性能；在该试验过程中，对交流电源施加一组规定的电压波动，并确定照明设备对干扰的抗扰度。 除了上述两个目的外，照明设备的抗扰性能还可以针对交流电源上的有意电压波动进行测试，例如电源信号引起的电压波动。然而，本文件未对此进行详细描述。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 61547 describes an objective light flickermeter, which can be applied for the following purposes: - measuring the intrinsic performance of all lighting equipment without the application of voltage fluctuations in terms of illuminance flicker; during this measurement, the lighting equipment is supplied with a stable mains;- testing the immunity performance of lighting equipment against (unintentional) voltage fluctuation disturbance on the AC mains in terms of illuminance flicker; during this test a set of defined voltage fluctuations are applied to the AC mains and the immunity of the lighting equipment to the disturbance is determined. Apart from the above two purposes, the immunity performance of lighting equipment can also be tested against intentional voltage fluctuation on the AC mains arising for example from mains signalling. This is however not described in further detail in this document.All current amendments available at time of purchase are included with the purchase of this document.
