MC 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 electromagnetic fields. It is one of the important indicators of product quality, and 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
Test items:
1. Electromagnetic compatibility test (EMC test)
2. Safety regulation test LVD (in the new directive, this test is also required for battery input RF products)
3. Radio communication equipment test (RF test) according to the European ETSI standard
4. Notification of allowable spectrum in Europe
5. CTR (TBR) test
6 Electrical Safety and Health Protection Testing (SAR Assessment)
Process:
Firstly, the following documents need to be prepared:
1 Please refer to the "Application Materials" of the China Electromagnetic Compatibility Certification Center for the format of the electromagnetic compatibility certification application form 2. A copy of the "Enterprise Legal Person Business License" or registration certificate of the enterprise applying for certification 3. Proof materials of stable product quality and batch production capacity 4. Apply for the quality manual of the enterprise 5. An overview of the production process of the product applying for certification, in duplicate 6. Product manual 7. Product structure description in duplicate 8. Product electrical schematic diagram and printed circuit board diagram 9. List of key electromagnetic compatibility components of the product in duplicate (stamped with official seal) 10. Other relevant information required when needed
Secondly, submit the prepared materials and product samples to the relevant testing agency
Thirdly, the relevant testing agency will perform the following steps for testing
EMC testing steps:
1. Specify the test outline and rules
2. Determine the standards based on
3. Exchange test interface information
4. Check measuring instruments
5. Start sub item testing
6. Issue a test report
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:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
