1. What is CB certification?
CB certification is one of the electrical product safety certification systems established by the International Electrotechnical Commission (IECEE). With CB certification, a product can obtain a CB certificate and be recognized in multiple countries, simplifying the certification process when the product is sold in multiple countries. In today's globalized market, the importance of safety certification for electrical products is becoming increasingly prominent. As a global certification program initiated by the International Electrotechnical Commission (IEC), CB certification has become an important standard for the safety certification of electrical products, aiming to ensure that electrical products between different countries and regions can meet basic safety and performance requirements.
2. Background and development of CB certification
With the continuous expansion of the international market and the acceleration of the globalization process, the electrical product market in different countries and regions has gradually shown a trend of interconnection. In order to eliminate safety barriers between different countries and regions, the International Electrotechnical Commission (IEC) launched the CB certification program in the early 1970s. The program aims to promote the mutual recognition of electrical product safety certification worldwide, reduce the best barriers, and improve the competitiveness of products in the international market.
After decades of development, CB certification has become a widely recognized electrical product safety certification system worldwide. Manufacturers and importers of electrical products in more and more countries and regions choose to obtain CB certification to ensure the safety and compliance of their products with relevant standards.
3. The practice and application of CB certification
In order to obtain CB certification, companies need to submit an application to a designated certification body and undergo testing and evaluation in accordance with relevant standards and procedures. Once the CB certification is obtained, enterprises can apply for transfer in multiple countries and regions, so as to obtain local electrical product safety certification.
Globally, many well-known manufacturers and importers of electrical products are actively involved in CB certification to ensure the safety and compliance of their products with relevant standards. Through CB certification, these companies are able to better meet market demand and improve the competitiveness and popularity of their products.
Fourth, what information is required for CB certification
4.1 Application form: A completed application form, including company information, product information, and testing information, etc.
4.2. Test report: Provide a test report issued by a qualified testing organization, and the test report should contain all product models for certification and meet the corresponding standards and certification requirements.
4.3 Samples: According to different product requirements, a certain number of samples are provided for testing and review.
4.4.Factory inspection report: The factory inspection will be carried out by a qualified third-party organization, and the corresponding factory inspection report will be issued.
4.5. Quality management system certificate: If the applicant has obtained the ISO9001 quality management system certificate, a copy of the certificate can be provided as part of the application materials.
4.6 Other relevant information: According to different products and certification requirements, other relevant information may be required, such as product specifications, circuit diagrams, etc.
5. Steps of the CB certification process
5.1. Preliminary consultation and evaluation: Enterprises should first clarify whether their products meet the requirements of CB certification and understand the relevant standards and regulations. At the same time, a suitable certification body is selected for consultation and evaluation.
5.2.Submit the application: Submit the application to the selected certification body and attach the necessary technical information, such as product specifications, circuit diagrams, lists of key parts, etc.
5.3 Type test: The certification body will conduct a type test on the applied product to verify whether it meets the relevant standards. In this process, enterprises need to cooperate in providing necessary samples and materials.
5.4. Factory inspection: The certification body will inspect the production facilities of the enterprise to ensure that its production process and quality control system meet the requirements.
5.5 Issuance of Certificate: If the product has passed the test and factory inspection, the certification body will issue a CB certificate for it. The certificate will indicate the model number, manufacturer name and manufacturing address of the product.
5.6. Continuous supervision and maintenance: After obtaining the certificate, the enterprise needs to accept the regular supervision and random inspection of the certification body to ensure that the product continues to meet the relevant standards.
6. Test standards for CB certification
Test Standards for CB CertificationThe Test Standards for CB Certification are a global certification standard developed by the International Electrotechnical Commission (IEC) to ensure that the safety performance of electrical equipment and components complies with relevant standards and regulations. Here are some of the key takeaways from the testing criteria for CB certification:
6.1 Test Scope: The test scope of CB certification is very wide, including all kinds of electrical equipment and components, such as household appliances, lamps, power tools, wires and cables, etc. These devices and components need to be tested according to the appropriate test standards to ensure that their safety performance meets the requirements.
6.2 Test items: The test items of CB certification include electrical strength, grounding resistance, insulation resistance, leakage current, withstand voltage, etc. These test items are designed to ensure that electrical equipment and components are free from hazards such as electric shock and fire under normal operating conditions.
6.3 Test equipment: CB certified test equipment includes a variety of electrical test instruments and equipment, such as voltage tester, current tester, insulation resistance tester, withstand voltage tester, etc. These test equipment need to comply with relevant standards and regulations to ensure the accuracy and reliability of test results.
6.4 Test process: The test process of CB certification includes the following steps: applying for certification, submitting samples, sample testing, issuing reports, and issuing certificates. In this process, companies applying for certification need to submit samples to the certification body and test them in accordance with the specified test standards. After the test is completed, the certification body will issue the corresponding report, and if the sample meets the requirements of the standard, a CB certification certificate will be issued.
6.5. Update of testing standards: With the continuous development of science and technology and the introduction of new regulations, the testing standards of CB certification are also constantly updated and improved. Therefore, enterprises applying for certification need to pay attention to the latest test standards issued by the certification body at any time, so as to adjust their products and production processes in time to ensure that they meet the requirements.
7. Summary
By actively participating in CB certification, enterprises can continuously improve their strength and competitiveness, and better integrate into the global market system. At the same time, countries and relevant institutions also need to strengthen cooperation and exchanges to jointly promote the development and improvement of electrical product safety certification, and provide consumers around the world with safer, more reliable and high-quality electrical products.
