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 60968 has been prepared by subcommittee 34A: Lamps, of IEC

technical committee 34: Lamps and related equipment.

This third edition cancels and replaces the second edition published in 2012. This edition

SELF-BALLASTED FLUORESCENT LAMPS
FOR GENERAL LIGHTING SERVICES –
SAFETY REQUIREMENTS
1 Scope

This International Standard specifies the safety and interchangeability requirements, together

with the test methods and conditions required to show compliance of tubular fluorescent

lamps with integrated means for controlling starting and stable operation (self-ballasted

fluorescent lamps).

These lamps are intended for domestic and similar general lighting purposes, having a rated

voltage of 50 V to 250 V, having a rated frequency of 50 Hz or 60Hz and having IEC 60061-1

compliant caps.

For a cap-holder system not specifically mentioned in this standard, the relevant information

on safety related tests provided by the manufacturer will apply.
The requirements of this standard relate only to type testing.
Recommendations for whole product testing or batch testing are given in Annex A.

This part of the standard covers photobiological safety according to IEC 62471 and

IEC TR 62471-2. Blue light and infrared hazards are below the level which requires marking.

2 Normative references

the lamp with the UV hazard function S (λ). Information about the relevant UV hazard function is given in

IEC 62471. It only relates to possible hazards regarding UV exposure of human beings. It does not deal with the

possible influence of optical radiation on materials, like mechanical damage or discoloration.

3.9
test family

lamp groups which are distinguished by common features of materials relevant to the test

applied
4 General requirements and general test requirements

4.1 Self-ballasted lamps shall be so designed and constructed that in normal use they

function reliably and cause no danger to the user or surroundings.
In general, compliance is checked by carrying out all the tests specified.

4.2 All measurements unless otherwise specified in this standard, shall be carried out at

rated voltage and frequency and in a draught-proof room. The ambient temperature shall be

from 23 °C to 27 °C inclusive and shall not vary by more than 1 °C during the measurements.

If lamps are rated for alternative frequencies the test shall be carried out at the most onerous

of these.
The test voltages are specified in the relevant clauses.

4.3 Self-ballasted lamps are non-repairable, factory sealed units. They shall not be opened

for any tests with exemption of 13.2. In the case of substantiated doubt based on the

inspection of the lamp and the examination of the circuit diagram, and in agreement with the

manufacturer or responsible vendor, lamps specially prepared so that a fault condition can be

simulated shall be submitted for testing (see Clause 13 and Clause 15).
5 Marking
5.1 Lamp marking
The following information shall be marked on the lamp.

1) Mark of origin (this may take the form of a trademark, the manufacturer's name or the

name of the responsible vendor).
2) Rated voltage(s) or rated voltage range (marked "V" or "volts").
3) Rated power (marked "W" or "watts").
4) Rated frequency (frequencies) (marked in "Hz").

5) Any further information needed to identify the product type e.g. model number or type

reference.
5.2 Additional marking

In addition the following information shall be given by the lamp manufacturer either on the

lamp, the packaging or in the installation instructions.
1) Rated lamp current.

2) For lamps with a weight significantly higher than that of the lamps for which they are a
