What are the contents of TV 3c certification testing? Television has made people's lives more diverse. All televisions sold in the market need to pass 3C certification, the full name of which is the "Compulsory Product Certification System". It is a product qualification evaluation system implemented by the Chinese government in accordance with laws and regulations to protect consumers' personal and national safety, strengthen product quality management, and implement mandatory product certification system in China. The 3C certification for television will be tested in accordance with GB8898 "Safety Requirements for Audio, Video and Similar Electronic Equipment", GB13837 "Limits and Measurement Methods for Radio Disturbance Characteristics of Sound and Television Broadcasting Receivers and Related Equipment", and GB17625.1 "Electromagnetic Compatibility Limits - Harmonic Current Emission Limits (Input Current per Phase of Equipment ≤ 16A)". 1. Marking and instructions for use; 2. Structural requirements for preventing electric shock; 3. Contact current and protection against electric shock under normal working conditions; 4. Insulation requirements, electrical strength, surge; 5. Electrical clearance and creepage distance 6. Temperature rise and softening point under different combination conditions; 7. Fault setting test, relevant temperature test, and electric shock prevention inspection; 8. Components; 9. Mechanical strength, drop, vibration; 10. Conductor connection terminal; Grounding continuity test; 11. Power cord; 12. Electrical connection and mechanical fixation; 13. Stability and mechanical hazards; 14. Fire prevention; 15. Strong disturbance voltage of 9Iz~30MHz injection power supply; 16. 30~2150MHz antenna end disturbance voltage; 17. Local oscillator and intermediate frequency radiation strong disturbance field strength 30~1000MHz product emission strong disturbance field strength; 18. Harmonic current
