Scope

This document describes a measurement- and calculation-based method for determining the specific characteristics of the surge current of a single and/or multiple lighting products of the same type. The lighting products include:
—— Light sources with integrated control devices;
—— Control devices;
—— Luminaires.
The identified surge current characteristics are:
—— Peak surge current;
—— Duration of the surge current pulse.
This document applies to lighting products connected to a low-voltage power grid of AC 220 V 50 Hz.
Note: In Chapter 6, the method uses reference values for the reference (line) inductance and the reference (short-circuit) peak current, which reflect typical conditions in a 220 V AC installation.
