fundamental frequency and harmonics. The power analyser or digital power meter shall have
specified accuracies to within 200 kHz.
4.12 Measuring circuits
In case of controlgear with supplementary connection to the output circuit or sensors (e.g. to
detect fault or temperatures), all sensors and circuits have to be connected as in normal use.

The value of the standby power (P ) (total input power) is recorded when a steady
(CG)standby
state has been reached (temperature of the convertor – electronic controlgear).
The supply voltage for the measurement according to Figure 3 is defined in 4.7 and 4.13 of this
standard.
Measurement sequence:
1) Connect the DUT according to Figure 3.
2) Switch on the mains voltage.
3) Set the controlgear via the interface port (for example “digital addressable lighting
interface”) to the standby mode.
4) Await the thermal equilibrium.
5) Measure the standby power (total input power).
The standby power (P ) (total input power) of a convertor – controlgear is measured
(CG)standby
with one electronic lamp controlgear.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. A cet effet, l'IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent également aux
travaux. L'IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que l'IEC
s'assure de l'exactitude du contenu technique de ses publications; l'IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l'IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l'IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L'IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l'IEC. L'IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
