EMC testing, also known as Electromagnetic Compatibility (EMC), refers to the comprehensive evaluation of the interference level (EMI) and anti-interference ability (EMS) of electronic products in the electromagnetic field. It is one of the important indicators of product quality. The measurement of electromagnetic compatibility consists of a testing site and testing instruments. The purpose of EMC testing is to detect the impact of electromagnetic radiation generated by electrical products on the human body, public power grid, and other normal working electrical products EMC is a very important quality indicator, which not only affects the reliability and safety of the product itself, but also may affect the normal operation of other equipment and systems, and is related to the protection of the electromagnetic environment. The European Community government stipulates that starting from January 1, 1996, all electrical and electronic products must pass EMC certification and be labeled with the CE mark before they can be sold in the European Community market
Classification of EMC testing standards:
1. Product specific standards: Specific requirements for in vitro diagnostic equipment
2. Product specific standards: Standards for a certain type of product, such as EN 61326-1): Electromagnetic compatibility requirements for electrical equipment for measurement, control, and laboratory use Part 1: General requirements
3. General standards: A series of test methods and limit requirements are specified, And it provides the applicable environment for these method requirements, such as EN61000-6-2: General Standard for Industrial Zone Environmental Immunity, which is the basis for developing other EMC standards and usually does not involve specific product categories 4. Basic standards, such as EN61000-4-X series standards
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
