50 views admin 2021-08-30

LED display screen is used more and more widely. Whether for export or domestic sales, ensuring product safety is the primary concern. Therefore, it is essential to apply for relevant certification. What are the requirements for applying for CE certification for LED display screen exported to the EU? This article mainly introduces the relevant knowledge of LED display exported to the EU for CE certification. Let's have a look!

CE certification is no stranger to everyone. It is called the "pass" for export to the EU. It is composed of EMC (electromagnetic compatibility) + LVD (low voltage directive). Among them, EMC includes EMI (interference) + EMC (anti-interference), and LVD is generally known as safety security. Generally, low-voltage products with AC less than 50V and DC less than 75V can be exempted from LVD projects. Low voltage products only need to test EMC and issue ce-emc certificate. High voltage products need to test EMC and LVD and issue two certificates and reports ce-emc and CE-LVD. The export of LED display screen to EU for CE certification needs to be tested according to the standards of audio, video, information and communication technology equipment. Let me briefly introduce the general testing standards: LVD standard: en 62368-1, EMC standard: en 55032, en 55035, en 61000-3-2 and en 61000-3-3. The EMC test items for CE certification of LED display screen include the following aspects: 1. Radiation; 2. Conduction; 3. Static electricity; 4. Conducted anti-interference; 5. Radiation immunity; 6. Pulse, etc.

The CE certified LVD test items of LED display screen include the following aspects: 1. Fault (test); 2. Impact; 3. Vibration; 4. Impact; 5. Electrical clearance; 6. Creepage distance; 7. Electric shock; 8. Fever; 9. Overload; 10. Temperature rise test, etc. Data required for CE certification: 1. Generally 2-3 test samples; 2. Circuit schematic diagram; 3. Product manual or operation manual; 4. Application form (form provided by our company); 5. Parts list (BOM).
