1. Samples: The number of samples required to be submitted for each certification is different, so please consult the magnetic field testing. The samples submitted must be officially qualified, and their internal electrical structure and appearance must be consistent with the bulk products exported in the future. The trademark and model on the sample must be clear and reliable.

2. Documentation: full names and detailed contact addresses of applicants and manufacturers; Product instructions; List of product parts; Product structure diagram; Product nameplate (label); Electrical schematic diagram and working principle description of the product; Other product characteristics.

3. Product instructions: product technical conditions (or company standards), establish technical data; Electrical schematic diagram, circuit diagram and block diagram of the product; List of key components or raw materials (please select products with European certification mark); Copy of the whole machine or component; Other necessary information.

In addition to meeting the requirements of the finished product standards of related products, the certification standards of lithium ion batteries must also meet the requirements of the IEC certification standard of batteries, IEC62,133. That is, CB verification of rechargeable batteries must comply with IEC certification standards IEC60950 and IEC62133. The production process of battery and battery cell is relatively complex. The battery manufacturing company should understand the details of the standard before testing and verification and control them during production to avoid delay in the test due to non-compliance with IEC62133 standard.

Because lithium is a metal that is particularly prone to chemical reaction and easy to extend and burn, accidents often occur in the packaging and transportation of lithium ion batteries, such as improper handling, combustion and explosion. Therefore, more and more attention has been paid to the accidents caused by non-standard behaviors in packaging and transportation. Many international organizations have issued many regulations, and various management organizations have become more strict, improving operation requirements, and constantly revising regulations and rules.
