IEC 63129:2020 pdf free download Determination of inrush current characteristics of lighting products
This document describes a method, based on measurements combined with calculations, todetermine specific characteristics of the inrush current of single and/or multiple lighting productsof the same type. Lighting products include the following:
. light sources with integrated controlgear,
.controlgear,
. luminaires.
The inrush current characteristics that are determined are.the peak inrush current,
the inrush current pulse duration.
This document applies to lighting products connected to low-voltage 230 V AC 50/60 Hzelectrical supply networks.
NOTE In Clause 6 it is stated that the methodology applies reference values for the reference (line) inductance andthe reference (short circuit) peak current which reflect the typical situation in a 230 v AC installation.

3.1
bidirectional diode thyristorDIAC
two-terminal thyristor having substantially the same switching behaviour in the first and thirdquadrants of the current-voltage characteristic
[SOURCE: IEC 60050-521:2002,521-04-66]
3.2
bidirectional triode thyristorTRIAC
three-terminal thyristor having substantially the same switching behaviour in the first and thirdquadrants of the current-voltage characteristic
3.3
circuit-breaker
mechanical switching device, capable of making, carrying and breaking currents under normalcircuit conditions and also making, carrying for a specified duration and breaking currents underspecified abnormal circuit conditions such as those of short circuit
[SOURCE: IEC 60050-441:2000,441-14-20]
3.4
control gearcontrolgear
<for an electric light source> unit inserted between the power supply (IEV 151-13-75) and atleast one light source, which serves to supply the light source(s) with its (their) rated voltage orrated current, and which can consist of one or more separate components
Note 1 to entry: The control gear can include means for igniting，dimming，correcting the power factor andsuppressing radio interference, and further control functions.
Note 2 to entry: The control gear consists of a power supply (IEV 151-13-76) and a control unit.Note 3 to entry: The control gear can be partly or totally integrated in the light source.
Note 4 to entry: The terms “control gear”and “controlgear”are interchangeable.In lEC standards,the term”controlgear” is commonly used.
