This standard specifies the safety requirements for organic light-emitting diode (OLED) light sheets and panels used for general lighting in indoor and similar situations. This standard applies to OLED light sheets and panels powered by a 50Hz or 60Hz AC power supply with a frequency not exceeding 120V DC or a frequency not exceeding 50V. Note 1: At this stage, only test methods for DC-powered OLED panels are provided, and corresponding provisions for AC-powered OLED panels are under consideration. Note 2: The structure of the OLED light sheet and panel is shown in Appendix A. Note 3: OLED lighting systems including OLED panels or modules are shown in Appendix D.
