▍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.

The UNECE (United Nations Economic Commission for Europe) on the TDG (Transport of Dangerous Goods) has published the 23rd revised version of the Model Regulations for Recommendations on the Transport of Dangerous Goods. A new revised version of the Model Regulations is issued every two years. Compared with version 22, the battery has the following changes:
3551 SODIUM ION BATTERIES with organic electrolyte
3552 SODIUM ION BATTERIES CONTAINED IN EOUIPMENT Or SODIUM ION BATTERIESPACKED WITH EOUIPMENT, with organic electrolyte
3556 VEHICLE, LITHIUM ION BATTERY POWERED
3557 VEHICLE, LITHIUM METAL BATTERY POWERED
3558 VEHICLE, SODIUM ION BATTERY POWERED
Cells and batteries, cells and batteries contained in equipment, or cells and batteries packed with equipment containing sodium ion, which are a rechargeable electrochemical system where the positive and negative electrode are both intercalation or insertion compounds, constructed with no metallic sodium (or sodium alloy) in either electrode and with an organic non aqueous compound as electrolyte, shall be assigned to UN Nos. 3551 or 3552 as appropriate.
Note: Intercalaled sodium exists in an ionic or quasi-atomic form in the lattice of the electrode material.
They may be transported under these entries if they meet the following provisions:
a) Each cell or battery is of the type proved to meet the requirements of applicable tests of the Manual of Tests and Criteria, part Ill, sub-section 38.3.
b) Each cell and battery incorporates a safety venting device or is designed to preclude a violent rupture under conditions normally encountered during transport;
c) Each cell and battery is equipped with an effective means of preventing external short circuits;
d) Each battery containing cells or a series of cells connected in parallel is equipped with effective means as necessary to prevent dangerous reverse current flow (e.g., diodes, fuses, etc.);
e) Cells and batteries shall be manufactured under a quality management program as prescribed under 2.9.4 (e) (i) to (ix);
f) Manufacturers and subsequent distributors of cells or batteries shall make available the test summary as specified in the Manual of Tests and Criteria, part Ill, sub-section 38.3, paragraph 38.3.5.
