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

Information for luminaire design
Internal short circuits can pose a risk to users and should be considered when designing
luminaires incorporating OLED products.
An internal short circuit has a resistance significantly lower than that of the organic
electroluminescent layers. This alters the current distribution through the OLED product and
usually leads to a significantly increased current density at the location of the internal short
circuit. As a result, (parts of) the OLED product will no longer emit light.
The internal short circuit typically has a non-zero residual resistance. Due to this residual
resistance power is consumed in the internal short circuit resulting in significant heat
generation. Local temperatures in excess of 100 °C can be observed and are maintained until
the OLED product is no longer powered.
If a constant current power supply is used, the voltage drop across the OLED will typically be
lowered, reducing total power consumption. If a constant voltage power supply is used, the
current will typically be increased until it is limited by the power supply or until the voltage
drop across the internal short circuit matches that of the OLED product under normal
operation, generally increasing power consumption significantly.
Temperatures created by a short circuit can be measured for example by applying a
thermocouple to the OLED product at the location of the short circuit. Internal short circuits
can be created for this purpose by the procedure described in 6.3. A thermocouple should be
applied after the short is generated but before the OLED product is powered for the first time.
NOTE Temperatures measured in this way can differ from temperatures that occur in products under fault
conditions as the method of generating an artificial internal short circuit differs from faults in actual products.
Possible risks from internal short circuits include:
– burns or scalds from touching the hot spot;
– ignition of flammable materials in the vicinity of the OLED product;
– ignition of flammable materials placed on the OLED product by users;
– faults of other components due to operation under abnormal conditions;
– splinters, melting material, etc. covered in 6.3.
Luminaire designers should assess the risk that is posed by such an internal short circuit. The
following should be taken into consideration:
– knowledge of users about OLED product fault conditions compared with conventional
lamps (OLED products are often touchable in normal operation but may be hot in fault
conditions);
– appearance (visibility) of internal short circuit to user;
– accessibility of OLED product and internal short circuit;
– temperature increase from internal short circuits compared to normal operating
temperatures of the OLED product;
– temperature generated by internal short circuits and burn thresholds for skin (see
IEC Guide 117);
– total power dissipated in the internal short circuit.
Adequate measures should be taken to minimize the risk to users.

(normative)
Method of provoking an internal short circuit
C.1 Method for an OLED panel with glass substrates
An internal short circuit shall be provoked by applying a small solder tip (preheated to
minimum 430 °C) to the glass surface or by laser treatment. The solder tip shall not be
applied for longer than necessary and shall be removed immediately when a short has been
created.
In case the final product of an OLED panel has an external outcoupling system (e.g.
outcoupling foil) or a plastic film, slightly peel off the external layer just enough to expose the
glass and allow for the provoking of the internal short circuit and then reattach the peeled off
layer to the glass after the short circuit has been created.
C.2 Method for an OLED panel with flexible plastic substrates
In the case of an OLED panel equipped with a flexible plastic substrate, the internal short
circuit shall be provoked by applying vertical pressure on the surface of the panel with a round
tip of steel for about 1 s. The temperature of the tip shall be 25 °C ± 5 °C and the radius of
curvature of the round tip shall be 0,5 mm ± 0,05 mm. It is advisable that the force applied on
the tip be about 100 N.
