IEC TR 61547-1:2020(E) describes an objective light flickermeter, which can be applied for, amongst others, the following purposes:
- testing the intrinsic performance of all lighting equipment without voltage fluctuations;
- testing the immunity performance of lighting equipment against (unintentional) voltage fluctuation disturbance on the AC power port;
- testing the immunity performance of lighting equipment against intentional voltage fluctuation on the AC power port arising for example from ripple control systems.
This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a. the title of Part 1 has been changed to reflect the more general application of the objective flickermeter;
b. the specific voltage fluctuation immunity test method has been extended for lighting equipment rated for 120 V AC and 230 V AC, 50 Hz and 60 Hz.
