▍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.

UL 2054 Ed.3 was released on November 17, 2021. As a member of the UL standard, MCM participated in the review of the standard, and made reasonable suggestions for the modification which was adopted afterwards.
The changes made to the standards are mainly involved with five aspects, which are paraphrased as followings:Miscellaneous revisions are made throughout the Standard; Sections 2 – 5, 6.1.2 – 6.1.4, 6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, Section 23 title, 24.1, Appendix A.Clarification of requirements for adhesive labels; Section 29, 30.1, 30.2.Addition of the requirements and methods of Mark Durability Test .
Made Limited Power Source Test an optional requirement; 7.1.Clarified the external resistance in the test in 11.11.The Short Circuit Test was stipulated to use copper wire to short circuit positive and negative anodes on section 9.11 of original standard, now was revised as using 80±20mΩ external resistors.
Addition of section 6.3: General requirements for the structure of wires and terminals:The wire should be insulated, and should meet the requirements of UL 758 while considering whether the possible temperature and voltage encountered in the battery pack is acceptable.
Wiring heads and terminals should be mechanically reinforced, and electrical contact should be provided, and there should be no tension on the connections and terminals. The lead should be safe, and kept far away from sharp edges and other parts that might harm the wire insulator.
