What kind of products should do EMC testing

 The following types of products typically require an EMC testing

1. Home appliances: such as TVS, refrigerators, washing machines, air conditioners, microwave ovens, rice cookers, etc. These products may produce electromagnetic radiation or electromagnetic interference by other electrical appliances in daily use.

2. Information technology equipment: including personal computers, servers, routers, switches, printers, scanners, mobile phones, tablet computers, notebook computers, etc., these devices are sensitive to the electromagnetic environment and may produce electromagnetic interference.

3. Industrial control and automation equipment: PLC (programmable logic controller), DCS (decentralized control system), frequency converter, motor driver, industrial robots, etc., these equipment operate in the industrial environment, the requirements for electromagnetic compatibility are very high.

4. Medical equipment: electrocardiogram machine, monitor, ultrasonic diagnostic instrument, hemodialysis machine, etc. The electromagnetic compatibility of medical equipment is directly related to the patient's life safety and the accurate operation of the equipment.

5. Automotive electronics: vehicle audio, navigation system, engine control system, safety system (such as ABS, ESP), etc. The EMC performance of automotive electronic products is directly related to the safety and reliability of the vehicle.

6. Lighting equipment: LED lamps, fluorescent lamps, energy-saving lamps, etc., especially intelligent lighting systems, need to ensure the electromagnetic compatibility with other smart home devices.

7. Military and aerospace equipment: radar, communication equipment, navigation system, satellites, uav vehicles, etc. These equipment work in extreme electromagnetic environment and have extremely high requirements for EMC performance.

8. Radio communication products: mobile phone base station, radio broadcasting and transmitting equipment, walkie-talkie, wireless remote control, etc., these products need to meet

the EMC requirements of radio spectrum management agencies.

The purpose of EMC testing is to ensure that the design, production, and use without unacceptable electromagnetic interference from other equipment or systems.

This helps to improve the overall quality of products, protect user safety, and meet the requirements of laws and regulations.

Electric blankets must obtain CE certification to export to the EU

  CE certification is a mandatory certification mark for products entering the European market indicating that the product meets the basic requirements of the EU's Technical Coordination and Standardization New Method Directive. The CE certification access model adopted by the EU market for electric blankets includes the following five parts: Low voltage instruction (LVD 2014/35/EU): Ensure the safe use of electric blankets under low voltage. Electromagnetic Compatibility Directive (EMCD 2014/30/EU): to ensure that the electric blanket does not produce electromagnetic interference to other electronic devices when used. Energy efficiency Directive (ErP): requires electric blankets to meet certain energy efficiency standards to reduce energy consumption. Directive to limit the use of certain harmful components in electronic and electrical products (RoHS): limits the use of certain harmful substances, such as lead, mercury, hexavalent chromium, etc., in electric blankets. Electronic a...

C-tick authentication concept A/c-tick is A certification mark for Communications equipment issued by the Australian Communications Authority (ACA).Manufacturers and importers must follow the next step in using A-Tick: : 1. Product implementation ACAQ technical standard test 2. Register the use of A/C-Tick to ACA 3. Fill in the Declaration of Conformity Form and keep the product with the record C - tick certification In communication products or equipment with A/C - the identity of the Tick marks (label) 5, sales to consumers A - Tick only applies to communication products, electronic products, mostly apply C - Tick, but electronic products if the application is A - Tick, do not need to apply for the C - other Tick.Since November 2001, EMI in Australia/New Zealand has applied for a merger;If the product is to be sold in the two countries, the following documents must be in place before marketing, in case the authorities of the Australian Communications Authority or the Ministry of Ec...
