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 62868-1 has been prepared by subcommittee 34A: Lamps, of IEC

INTRODUCTION

This part of IEC 62868 provides a set of general safety requirements and tests of OLED light

sources which are applicable to general indoor lightings. This document specifies the

requirements and tests for simple OLED light sources which do not include active electronic

components and consist of rigid substrates. It applies to the common requirements and tests

to verify the safety of all types of OLED light sources such as OLED modules and flexible

OLED panels. This document applies to OLED panels and tiles which consist of rigid

substrates. It also applies to any OLED light sources which are not specified in IEC 62868-2

(all parts) .

The parts which make up the IEC 62868-2 series, in referring to any clauses of this document,

specify the extent of application of this document; they also include additional requirements

and tests as necessary.

Where the requirements of any clauses of this document are referred to in the various parts

that make up the IEC 62868-2 series by the phrase "The requirements of Clause n of

IEC 62868-1 apply", this phrase will be interpreted as meaning that all requirements of the

clauses in question of this document apply, except any which are clearly inapplicable to a

particular type of OLED light source covered by the Part n of the IEC 62868-2 series

concerned.

The safety requirements of this document are intended to ensure that electrical lightings

constructed in accordance with this document do not endanger the safety of users or

properties when the light sources are properly installed, maintained and used in applications.

Particular requirements and tests for OLED light sources which include any active electronic

components and consist of flexible substrate will be the subject of a separate standard, as the

need arises.

operated OLED products are under consideration.

NOTE 2 The construction of OLED tiles and panels is illustrated in Figure A.1 to Figure A.4 in Annex A.

NOTE 3 The OLED lighting system consisting of OLED panels or modules is illustrated in Annex D.

NOTE 4 This document applies to OLED light sources (tiles, panels, modules) which are composed of OLED

luminaires or OLED lamps, and it is intended so that the OLED light source in accordance with this document fits in

IEC 60598 (all parts) as a component of lighting equipment, in combination with other components.

NOTE 5 Where an appropriate Part 2 of IEC 62868 for an OLED light source does not exist, the nearest

applicable Part 2 of IEC 62868 can be used as a guide to the requirements and tests.
