IEC 62868-1:2020 pdf download-Organic light emitting diode (OLED) light sources for general lighting – Safety – Part 1: General requirements and tests.
6 Construction 6.1 General Wood, cotton, silk, paper and similar fibrous material shall not be used as insulation. Compliance is checked by inspection. 6.2 Mechanical strength The OLED product shall have sufficient mechanical strength. The following vibration test shall be performed. Compliance is checked by the vibration test. For the vibration test, the OLED product shall be mounted in accordance with 4.2. A sinusoidal vibration test is conducted in accordance with IEC 60068-2-6 with the following parameters: – displacement: 0,35 mm; – acceleration: 50 m/s 2 ; – frequency range: 1 0 Hz to 500 Hz; – axes of vibration: 3; – duration: 3 × 1 0 cycles (1 0 times per axis). After completion of the vibration test, the OLED product shall be operated for 1 5 min under the conditions specified in 4.2. Compliance: After the test, the OLED product is checked by inspection. Any splintered or broken glass is not accepted. Fire, smoke or flammable gas shall not be produced. The OLED product shall have no loosened parts which could impair safety. Electrical contacts which could not be touched before the vibration test (e.g. those in OLED products in accordance with Figure A.3 and Figure A.4) shall not have become accessible after the test.
6.3 Internal short circuit An OLED product with internal short circuit shall not cause any hazard. The following internal short test shall be performed. Compliance is checked by the internal short test. An internal short circuit shall be provoked intentionally in the OLED product under test in accordance with instructions given by the manufacturer or in accordance with 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 product shall not be operated.
The test sample of the OLED product shall be operated at the rated current for 30 min for testing. If the test sample does not generate an internal short circuit during the test operation, the internal short circuit test shall be repeated with the same sample. If none of the methods described in the manufacturer’s instructions and Annex C generate an internal short circuit after three attempts, the test sample passes the test. Compliance: An OLED product passes this test if there is no emission of flames or molten material during the test. Any hot material from the sample shall not ignite a tissue paper, as specified in 4.187 of ISO 4046-4:2016, spread below the OLED product. Any splintered or broken glass is not accepted.
