all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.

for measurement, this should be observed.

5 Method of measurement and calculation of total input power of controlgear –
lamp circuits and the efficiency of controlgear
5.1 Correction for ballast lumen factor
The total input power measured is corrected to a BLF of 0,95 for wire-wound magnetic
controlgear and of 1,00 for high frequency (HF) electronic controlgear. Additionally tolerances
of reference lamps are compensated.

5.2 Method of measurement
The measurements are carried out with the power meter connected to measure the total input
power into the controlgear – lamp circuit, using:
– for magnetic wire wound controlgear – lamp circuits:
the conditions specified in A.6.1 of IEC 60921:2004 and the test circuit of Figure A.1;
– for a.c. supplied electronic controlgear – lamp circuits:
the conditions specified in A.6.2 of IEC 60921:2004, as far as applicable, and the test
circuit of Figure A.2.
The value of the total input power (P ) is recorded when a steady state has been
tot.meas.
reached (controlgear temperature and lamp current stabilized).

---------------------- Page: 11 ----------------------
– 10 – 62442-1 © IEC:2011


The measurements with the controlgear under test in the controlgear – lamp circuit are to be

made with the rated supply voltage. P of a reference lamp, in some cases, may deviate
Lrated

from the nominal value of the lamp.


5.3 Measurement and calculation of the total input power of magnetic wire wound

controlgear – lamp circuits


The measured total input power (P ) of a controlgear – lamp circuit is measured with
tot.meas.

one controlgear and a reference lamp (or the number of reference lamps the controlgear is
designed to operate). The reference lamps shall conform to Annex D of IEC 60921:2004, in
addition the lamp current shall not deviate more than 1 % of the rated lamp current.


The measured total input power (P ) is corrected to a BLF of 0,95 and corresponds to
tot.meas.
that value that would be given by the reference lamp with rated setting in order to minimize the
error caused by the variation of the characteristics of the reference lamps used.
The corrected total input power of the ballast-lamp circuit (P ) is calculated using the
tot.ref.
following equation (2):
PLref.meas.
 
P = P  0,95−(PLref.meas.− PLrated) (2)
tot.ref. tot.meas.
PLmeas.
 
where
P is the total input power of the controlgear – lamp circuit under test corrected to
tot.ref.
comparable reference conditions (in watts);
P is the measured total input power into the controlgear – lamp circuit under test (in
tot.meas.
watts);
P is the measured lamp power in the circuit with reference ballast (in watts);
Lref.meas.
P is the measured lamp power in the circuit with test controlgear (in watts);
Lmeas.
P is the rated lamp power of relevant reference lamp according to the lamp data sheet
Lrated.
(in watts).
5.4 Calculation of the efficiency of magnetic wire wound controlgear
The ballast lumen factor of 0,95 for the light output of lamps operated with magnetic wire
wound controlgear requires the calculation of the efficiency of the magnetic controlgear using
