IEC 62868-2014 pdf Organic light emitting diode (OLED) panels for general lighting – Safety requirements

6.3 Internal short circuit An OLED panel with internal short circuit shall not cause any hazard. Compliance is checked by the following test: An internal short circuit shall be provoked intentionally in the OLED panel under test according to instructions given by the manufacturer or according to a method described in Annex C. The location of this internal short circuit shall be close to the edge of the light output area at around 2 mm distance. Before starting the test, the test sample of the OLED panel shall not be operated. The test sample of the OLED panel shall be operated at the rated current for 30 min for testing. If the test sample does not generate the internal short circuit during the test operation, the internal short circuit test shall be repeated with the same sample.
6.4 Wireways Wireways shall be smooth and free from sharp edges, burrs, flashes and the like, which might cause abrasion of the insulation of the wiring. Parts such as sharp-edged screws shall not protrude into wireways. Compliance is checked by inspection. 6.5 Resistance to dust, solid objects and moisture If an IP number is rated, the OLED panel shall comply with Section 9 of IEC 60598-1 . NOTE IP numbers for degrees of protection are explained in IEC 60598-1 Annex J. 7 Mechanical hazard An OLED panel with glass edges or corners shall be free from sharp edges or points that could create hazards during installation, normal operation or maintenance. An OLED panel with thin metal foil or thin plastic film shall have protections against sharp edges or points that could during installation, normal operation, or maintenance, create hazards. Compliance is checked by inspection and means of the sharp edge tester according to IEC TR 62854. 8 Fault conditions An OLED panel shall not impair safety under fault conditions that may occur during the intended use.
