Abstract

Overview

IEC 63129:2020 (consolidated with Amendment 1, 2025) defines a standardized method to determine inrush current characteristics of lighting products. The standard covers measurement and calculation procedures to obtain the peak inrush current and inrush current pulse duration for single or multiple devices under test (DUT) connected to low-voltage 230 V AC networks. Lighting products included are light sources with integrated controlgear, controlgear, and luminaires. The goal is to provide reliable inrush current data to ensure compatibility with switches, circuit breakers and other switchgear in building electrical installations.

Key topics and technical requirements

Measured characteristics
- Peak inrush current (Ipeak) - maximum absolute transient current on power-up.
- Inrush current pulse duration (tHx) - full width at x% of peak (commonly H10 and H50).
Measurement approach
- Method combines measurements and calculations; supports single and multiple DUTs.
- DC method is the default measurement setup; an AC method is provided as an alternative.
- Procedures for determining and applying adjustment resistances (Radj) to replicate installation conditions.
- Guidance on ignoring very short RF noise spikes and defining measurement windows (e.g., discounting current peaks for t
