▍What is CE Certification?

The CE mark is a “passport” for products to enter the EU market and the EU Free Trade Association countries market. Any stipulated products (involved in the new method directive), whether manufactured outside the EU or in EU member states, in order to circulate freely in the EU market, they must be in compliance with the requirements of the directive and relevant harmonized standards before being placed on the EU market , and affix the CE mark. This is a mandatory requirement of EU law on related products, which provides a unified minimum technical standard for the trade of products of various countries in the European market and simplifies trade procedures.

▍What is CE directive?

The directive is a legislative document established by the European Community Council and the European Commission under authorization of the European Community Treaty. The applicable directives for batteries are:

2006/66 / EC & 2013/56 / EU: Battery Directive. Batteries that comply with this directive must have a trash can mark;

2014/30 / EU: Electromagnetic Compatibility Directive (EMC Directive). Batteries that comply with this directive must have the CE mark;

2011/65 / EU: ROHS directive. Batteries that comply with this directive must have the CE mark;

Tips: Only when a product complies with all CE directives (the CE mark needs to be pasted), can the CE mark be pasted when all the requirements of the directive are met.

▍The Necessity of Applying for CE Certification

Any product from different countries that wants to enter the EU and the European Free Trade Zone must apply for CE-certified and CE marked on the product. Therefore, CE certification is a passport for products entering EU and the European Free Trade Zone.

▍Benefits of Applying for CE certification

1. EU laws, regulations, and coordinate standards are not only large in quantity, but also complex in content. Therefore, obtaining the CE certification is a very smart choice to save time and effort as well as to reduce the risk;

2. A CE certificate can help earning the trust of consumers and market supervision institution to a maximum extent;

3. It can effectively prevent the irresponsible allegations situation;

4. In the face of litigation, the CE certification will become legally valid technical evidence;

5. Once punished by EU countries, the certification body will jointly bear the risks with the enterprise, thus reducing the risk of the enterprise.

On November 27, 2023, “UN Manual of Tests and Criteria” (Rev. 8) was officially released on the United States website. “UN Manual of Tests and Criteria” (Rev. 8) adopts the revisions that made by the 11th session of the United Nations TDG and GHS Expert Committee on the “UN Manual of Tests and Criteria” (Rev. 7) and its Amendment 1. As the basic test for battery safety transportation, “UN Manual of Tests and Criteria” (Rev. 8) has added a new section of 38.3.3.2 “Testing of sodium ion cells and batteries”, and simultaneously added the exclusive entries related to sodium-ion batteries in the UN “Recommendation on the Transport of Dangerous Goods” (TDG) Rev. 23: UN 3551 and UN 3522.
T.1: Altitude simulation (cell and battery)
Test cells and batteries shall be stored at a pressure of 11.6 kPa or less for at least six hours at ambient temperature （20±5℃）Test cells and batteries are to be stored for at least six hours at a test temperature equal to 72℃and -40℃. This procedure is to be repeated until 10 total cycles are complete.
Cells and batteries are firmly secured to the platform of the vibration machine, with the vibration to be a sinusoidal waveform with a logarithmic sweep between 7 Hz and 200 Hz, and the amplitude at 0.8mm, for cell and small battery pack the maximum acceleration of 8 gn, and for large battery pack the maximum acceleration of 2 gn.Small cell: maximum acceleration of 150 gn, pulse duration of 6 milliseconds.Large cell: maximum acceleration of 50 gn, pulse duration of 11 milliseconds.
