Brief introduction to CE certification, quick understanding of CE certification

introduction to CE certification




CE certification is one of the necessary certifications for sales standards in the European market, effectively ensuring product quality and safety. This article will introduce product performance analysis, testing items, and standards.




1、 Product performance analysis




The CE certification covers a wide range of products, including household appliances, toys, electrical electronics, medical devices, mechanical equipment, and other fields. The products in each field have unique performance analysis. Below, we will take the electrical and electronic field as an example for analysis.




1.1 EMC performance testing




The measurement index of EMC tolerance is a standard that electrical and electronic product manufacturers must follow and must comply with European standards. EMC testing is a test that tests the degree of influence of various electronic devices in electromagnetic fields and whether they themselves generate interference. Only by passing EMC testing can we ensure that the product has no electromagnetic compatibility issues, is safe, reliable, and meets environmental requirements.




1.2 Safety performance testing




In the testing of electrical and electronic products that comply with European standards, safety performance testing involves some related testing items, including input voltage, insulation resistance, cable strength, grounding, temperature rise, etc. These test items can determine whether electrical and electronic products comply with European safety performance standards. Safety testing is one of the important tests to ensure the safety and reliability of products.




1.3 Reliability testing




Reliability test is to test the sustainable operation Achievement test of electrical and electronic products under various conditions, so as to ensure that they can continue to operate under the expected working environment, and can easily withstand various abnormal operations. We must persistently conduct reliability testing for products in different fields.




2、 Testing items




The testing items vary depending on the type of product. But overall, the following are the main contents of the testing project




2.1 Body size and weight




2.2 Power supply and interface specifications




2.3 Chassis and Housing Materials




2.4 Operation screen size and material specifications




2.5 Button and controller specifications




2.6 Material, design, and size specifications for electronic circuit boards




2.7 Engine motor parameter specifications




2.8 Power output and energy consumption test




2.9 Laser output specifications




2.10 Optical transparency test




2.11 Audio output specifications




2.12 Emissions Testing (CISPR 22/EN55022/FCC Part 15)




2.13 Safety testing (EN60950 1/IEC60335 1/IEC60601 1)




2.14 Immunity testing (EN55024/IEC61000 4)




2.15 Others (mechanical safety, waterproof testing, etc.)




3、 Standards




The CE certification standard is the foundation of sales standards in the European market, and the CE certification mark can also appear on the labels, product packaging, and instructions on machines. Therefore, these standards need to be very strict and standardized according to three-level standards, where E Level refers to the ordinary level, F Level is the enhanced level, and IEC Level is the international level. Each product must comply with three levels of CE certification standards.




Learn more about CE certification through the following Q&A




1. Is CE certification only applicable to the European market




CE certification is one of the standards for sales in the European market, but it also applies to products from non European markets entering the European market.




2. What is the development and implementation method of CE certification standards




The CE certification standard is jointly developed by the European Parliament and the Commission, and manufacturers can review and apply for CE certification based on the standard.




3. What is the application process for CE certification




The CE certification application process includes submitting a CE application, selecting a certification agency, submitting materials, conducting on-site audits, and receiving a CE certificate.
