Why should my products do EMC test

 The EMC (Electromagnetic Compatibility) test is a capability test to assess whether a device or system can function properly in an electromagnetic environment without producing unbearable electromagnetic interference (EMI) from anything in its surrounding environment.

Almost all electronic devices or systems, before marketing or use in certain occasions, require EMC testing to ensure that they meet the relevant national or international standards, thus protecting the equipment itself, users, and other surrounding equipment from electromagnetic interference.

The main reasons for requiring EMC (Electromagnetic Compatibility) testing are as follows:

Ensure the electromagnetic compatibility of the product

Avoid electromagnetic interference: EMC testing can assess the behavior of the product in the electromagnetic environment to ensure that it does not produce unacceptable electromagnetic interference (EMI) to other equipment or systems.

This interference may lead to performance degradation, failure or damage of other equipment.

Improve anti-interference capability: EMC testing also focuses on the product's resistance to external electromagnetic interference (EMS) to ensure that the product works properly in a complex electromagnetic environment without interference from other equipment or systems.

Compliance with the regulations and standards

Meet laws and regulations: Many countries and regions have established laws and regulations on electromagnetic compatibility, requiring specific types of products to pass EMC testing and obtain corresponding certification or license before they can be marketed or used in specific occasions.

Compliance with industry standards: In addition to the laws and regulations, many industries have also developed their own EMC standards to ensure the compatibility and reliability of their products within the industry.

Improve product quality and reliability

Improve stability: EMC testing reveals possible electromagnetic compatibility issues during product design, production and use to improve and optimize the product before launch and improve product stability and reliability.

Reduce the failure rate: Through the EMC test, the potential electromagnetic interference problems can be found and solved in time, so as to reduce the failure rate of the product in use, and improve user satisfaction.

Ensure user safety

Protect users from electromagnetic radiation hazards: For products that may produce electromagnetic radiation, EMC testing ensures that their radiation levels are within a safe range to protect the user from electromagnetic radiation hazards.

Ensure the safe operation of the equipment: For the products that need to be connected to the power grid or connected to other equipment, EMC testing can ensure their safe operation in the electromagnetic environment and avoid safety accidents caused by electromagnetic interference.

Promote international trade

International mutual recognition: Many international organizations and countries have established EMC test mutual recognition system, and products certified by EMC testing of specific institutions can obtain market access qualification in multiple countries or regions.

Reducing trade barriers: EMC tests can help reduce international trade barriers caused by electromagnetic compatibility issues and promote the smooth flow of global trade.

To sum up, EMC testing is of great significance in ensuring electromagnetic compatibility, compliance with regulations and standards, improving product quality and reliability, ensuring user safety, and promoting international trade.

Therefore, many products require EMC testing to meet the above requirements.

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...
