Organic light emitting diode (OLED) light sources for general lighting - Safety - Part 1: General requirements and tests
1 Scope
This document specifies the general safety requirements for organic light emitting diode (OLED) light sources for general lighting in indoor and similar applications.
This document specifies OLED products for use on DC supplies up to 1000 V or AC supplies up to 1000 V at 50 Hz or 60 Hz for indoors and similar general lighting purposes.
This document applies to any OLED light sources which are not covered by GB/T 39075-2 (all parts).
Note 1: Only test methods for DC operated OLED light sources are provided in this document. Provisions for AC 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 GB/T 39075 for an OLED light source does not exist, the nearest applicable Part 2 of GB/T 39075 can be used as a guide to the requirements and tests.

3 Terms and definitions
For the purpose of this document, the terms and definitions given in IEC 62504 and IEC TS 62972 and the following apply.
3.1
organic light emitting diode; OLED
light emitting semiconductor consisting of an electroluminescent zone made of organic compounds, situated between two electrodes
3.2
OLED tile
smallest functional OLED light source which cannot be separated into smaller OLED lighting elements containing at least one contact ledge with at least one positive and one negative pole for connection to the electrical power supply
3.3
OLED panel
independently operable unit OLED product containing an OLED tile and means of connection to the electrical supply
Note: An OLED panel may have a connector, PCB (printed circuit board), passive electronic components and optionally a frame.
3.4
OLED module
assembly of one or more OLED panels and active electronic components
Note: The classification of OLED modules is given in Annex E.
3.5
semi-integrated OLED module
OLEDsi module
OLED module which carries the control unit of the controlgear, and is operated by the separated power supply of the controlgear
3.6
integrated OLED module
OLEDi module
OLED module incorporating controlgear and any additional elements necessary for stable operation of the light source, designed for direct connection to the supply voltage
3.7
integral OLED module
OLED module, designed to form a non-replaceable part of a luminaire
3.8
built-in OLED module
OLED module, designed to form a replaceable part to be built into a luminaire, a box, an enclosure or the like and not intended to be mounted outside a luminaire
3.9
independent OLED module
OLED module, designed for being mounted or placed separately from a luminaire, from an additional box or enclosure or the like
Note 1: The independent OLED module provides all the necessary protection with regard to safety according to its classification and marking.
Note 2: An example of an independent OLED module is a system where the OLED module is connected via a glass fibre with the luminaire head.
3.10
rated value
quantity value for a characteristic of a product for specific operating conditions with the values and the conditions specified in the relevant standard, or assigned by the manufacturer or responsible vendor
3.11
type test
test or series of tests made on a type test sample for the purpose of checking compliance of the design of a given product with the requirements of the relevant standard
3.12
stabilization
keeping of an OLED product switched on under specified electrical input to obtain stable operation
Note: The mentioned operation can be photometric or electrical under specified conditions in the relevant test clause.
3.13
dark spot
small area remarkably darker than the surrounding light output area on the OLED product
Note: A dark spot can be due to lower current density or an open circuit in that area.
3.14
internal short circuit
unintentional conductive path between the OLED anode and OLED cathode localized on a small area
Note: An internal short circuit can look like a dark spot. It can lead to a significant heat generation in that area.
4 General
4.1 General requirements
An OLED product shall be designed and manufactured in such a way as to operate safely during its intended use and not to cause any danger to persons and the environment. In case of a failure of an OLED product it shall fail safely.
Reference to an OLED product also includes reference to OLED tiles in the requirements and tests of this document.
4.2 General test requirements
The tests, unless otherwise specified, are carried out at an ambient temperature of 25 °C ± 5 °C.
The tests shall be conducted at the rated current with a tolerance of 1 % unless otherwise specified in this document.
The OLED product under test shall be mounted in accordance with the manufacturer’s installation instructions. If more than one way of mounting is specified, the most onerous way shall be chosen for each test. For electrical tests, this is the position leading to the largest heat build-up of the light emitting surface. The orientation of the OLED product shall be maintained during the entire test.
5 Marking
5.1 Contents and location
Marking of the OLED product shall be done in accordance with Table 1.
