PERFORMANCE REQUIREMENTS
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

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.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60929 has been prepared by subcommittee 34C: Auxiliaries for

lamps, of IEC technical committee 34: Lamps and related equipment.

This fourth edition cancels and replaces the third edition published in 2006, IEC 60925

published in 1989, its Amendment 1 (1996) and its Amendment 2 (2001). This fourth edition

constitutes a technical revision. The essential change with respect to the third edition is the

extension to DC supplied control gear and the deletion of the requirements for digital signal

control of electronic control gear.
The text of this standard is based on the following documents:

INTRODUCTION

This International Standard covers performance requirements for electronic control gear for

use on a.c., at 50 Hz or 60 Hz, and/or d.c. supplies up to 1 000 V with operating frequencies

deviating from the supply frequency, associated with tubular fluorescent lamps as specified in

IEC 60081 and IEC 60901, and other tubular fluorescent lamps for high frequency operation,

still to be standardised.

These control gear are intended to operate lamps at various frequencies including high

frequencies and at various lamp powers. Attention is drawn to the fact that operating

frequencies below 20 kHz may cause audio noise disturbance, whereas frequencies above

50 kHz may increase radio interference problems.

Some lamps may be specifically designed for high-frequency operation on high-frequency

control gear. Two starting modes, preheat and non-preheat, are described.

NOTE Lamps, only specified for preheat starting may be operated on other types of circuits. The control gear

manufacturer should provide test data which shows satisfactory starting and operation similar as the ones stated in

Clause 6.

In order to obtain satisfactory performance of fluorescent lamps and electronic control gears,

it is necessary that certain features of their design be properly co-ordinated. It is essential,

therefore, that specifications for them be written in terms of measurement made against some

common baseline of reference, permanent and reproducible.

These conditions may be fulfilled by reference ballasts. Moreover, the testing of control gear

for fluorescent lamps will, in general, be made with reference lamps and, in particular, by

comparing results obtained on such lamps with control gear to be tested and with reference

ballast.

Whereas the reference ballast for frequencies of 50 Hz or 60 Hz is a self-inductive coil, the

high-frequency reference ballast is a resistor because of its independence of frequency and

the lack of influence of parasitic capacitance.

AC and/or DC-SUPPLIED ELECTRONIC CONTROL GEAR
FOR TUBULAR FLUORESCENT LAMPS –
PERFORMANCE REQUIREMENTS
1 Scope

This international Standard specifies performance requirements for electronic control gear for

use on a.c. at 50 Hz or 60 Hz and/or d.c. supplies, both up to 1 000 V, with operating

frequencies deviating from the supply frequency, associated with fluorescent lamps as

specified in IEC 60081 and IEC 60901, and other fluorescent lamps for high-frequency

operation.

NOTE 1 Tests in this standard are type tests. Requirements for testing individual control gear during production

are not included.

NOTE 2 There are regional standards regarding the regulation of mains current harmonics and immunity for end-

products like luminaires and independent control gear. In a luminaire, the control gear is dominant in this respect.

Control gear, together with other components, should comply with these standards.

– 8 – 60929 © IEC:2011
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
starting aid

a conductive strip affixed to the outer surface of a lamp, or a conductive plate which is spaced

within an appropriate distance from the lamp

A starting aid is usually connected to earth potential, and can only be effective when it has an

adequate potential difference from one end of the lamp.
3.2
ballast lumen factor
blf

ratio of the luminous flux of the lamp when the ballast under test is operated at its rated

voltage, to the luminous flux of the same lamp operated with the appropriate reference ballast

supplied at its rated voltage and frequency
3.3
reference ballast

special ballast, either inductive for lamps for operation on a.c. mains frequencies, or resistive

for lamps for operation on high frequency

It is designed for the purpose of providing comparison standards for use in testing ballasts, for

the selection of reference lamps and for testing regular production lamps under standardised

conditions. It is essentially characterised by the fact that, at its rated frequency, it has a stable

voltage/current ratio which is relatively uninfluenced by variations in current, temperature and

magnetic surroundings, as outlined in this standard.
[IEC 60050-845:1987, 845-08-36, modified]
3.4
reference lamp

lamp selected for testing control gear which, when associated with a reference ballast, has

electrical characteristics which are close to the nominal values as stated in the relevant lamp

standard
NOTE Specified conditions are given in Annex C.
3.5
total circuit power

total power dissipated by control gear and lamp in combination, at rated voltage and

frequency of the control gear
3.6
circuit power factor

power factor of the combination of a control gear and the lamp or lamps for which the control

gear is designed
3.7
preheat starting

type of circuit in which the lamp electrodes are brought to emission temperature before the

lamp actually ignites
---------------------- Page: 10 ----------------------
60929 © IEC:2011 – 9 –
3.8
non-preheat starting

type of circuit which utilises a high open-circuit voltage causing secondary electron emission

from electrodes
3.9
electronic control gear life time

declared average life time at which 90 % of the electronic control gears are still operating

NOTE 1 In the context of life time, an electronic control gear is “operating” if it still fulfils it intended functions.

NOTE 2 The manufacturer apply suitable methods, e.g. statistical calculation and/or reliability testing.

3.10
ambient temperature

temperature range of the air surrounding the electronic control gear declared by the

manufacturer to indicate the normal operating temperature range for the electronic control

gear

NOTE 1 The lifetime of the electronic control gear is given at the ambient temperature ta; for ease of

measurement, also the corresponding temperature of the tc point is given.

NOTE 2 The measurement test condition for the ambient temperature assigned to the DUT should be in

accordance to Annex D of IEC 61347-1 at the rated voltage.
4 General notes on tests
4.1 Tests according to this standard are type tests.

NOTE The requirements and tolerances permitted by this standard are based on the testing of a type test sample

submitted by the manufacturer for that purpose. In principle this type test sample should consist of units having

characteristics typical of the manufacturer’s production and be as close to the production centre point values as

possible.

It may be expected with the tolerances given in this standard that products manufactured in accordance with the

type test sample will ensure compliance with the standard for the majority of the production. However, due to the

production spread, it is inevitable that there will sometimes be products outside the specified tolerances. For

guidance on sampling plans and procedures for inspection by attributes, see IEC 60410.

4.2 The tests are carried out in the order of the clauses, unless otherwise specified.

4.3 One control gear is submitted to all tests, unless otherwise stated.

4.4 In general, all tests are made on each type of control gear or where a power range of

similar control gear is involved, for each rated power in the range or on a representative

selection from the range as agreed with the manufacturer.

4.5 The tests are made under the conditions specified in Annex A. Lamp data sheets not

published in an IEC publication shall be made available by the lamp manufacturer.

4.6 All control gear specified in this standard shall comply with the requirements of

IEC 61347-2-3.

4.7 Attention is drawn to lamp performance standards which contain “information for

control gear design”; this should be followed for proper lamp operation; however, this

standard does not require the testing of lamp performance as part of the type test approval for

control gear.

5 Marking
5.1 Mandatory marking

Electronic control gear shall be clearly marked with the following mandatory marking as

applicable.
a) Circuit power factor, e.g. 0,85.

If the power factor is less than 0,95 capacitive, it shall be followed by the letter C, e.g.

0,85 C.
The following marking shall also be added, if appropriate:

b) The symbol Z which indicates that the control gear is designed to comply with the

conditions for audio-frequency impedance.
5.2 Additional mandatory Information

In addition to the above mandatory markings, the following information shall either be given

on the control gear or be made available in the manufacturer’s catalogue or the like.

a) a clear indication regarding the type of starting, viz. preheat or non-preheat;

b) indication whether a control gear needs a starting aid;
c) ballast lumen factor if different from 1 ± 0,05;

d) life time of the control gear is linked to the ambient temperature and the measured

temperature on the reference point tc.

For the information, the format of Table 1 has to be used. Corresponding to the fixed

ambient temperature values 40 °C, 50 °C and 60 °C, the values of the temperature

measured on the reference point tc and the declared life time have to be inserted by the

manufacturer. The value of the temperature of the tc point given in the table shall never

exceed the tc (IEC 61347-1), therefore, in that case, the column where the temperature of

tc-point exceeds tc will be left blank; but at least the column with ambient temperature

40 °C shall always be filled.
