Introduction to battery CB certification

CB system (IEC system for qualification testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of IECEE member states test the safety performance of electrical products based on IEC standards, and the test results, namely CB test report and CB test certificate, are mutually recognized in IECEE member states. Up to now, 66 certification bodies in 51 countries and more than 270 CB laboratories under them have participated in this mutual responsibility system. The purpose is to reduce international trade barriers that must meet the certification or approval criteria of different countries. IECEE is the abbreviation of the International Electrotechnical Commission Organization for qualification testing and certification of electrical products.

After the enterprise obtains the CB certificate from one of the certification bodies, due to the mutual recognition agreement, it can no longer repeat the test, but only do the report review and supplementary test or national difference test, which can be converted into the safety certification certificate of other member states.

Battery CB certification product range

Portable sealed secondary battery unit and battery (Group) containing alkaline or non acid electrolyte

IEC62133 test standard:

Secondary single cells and batteries (packs) containing alkaline or non acid electrolyte: Safety requirements for portable sealed secondary single cells and batteries (packs) used in portable equipment.

Battery CB test items

1. Low rate charging

2. Vibration

3. Temperature cycle

4. External short circuit

5. Free fall

6. Hot stamping

7. Crush the battery (front and side extrusion)

8. Low voltage test

9. Overcharge test

10. Over discharge test

11. High rate charging

CB certification process

1. Fill in the application form;

2. Provide product information;

3. Send samples;

4. If the test is OK, submit the report to the certification body (NCB);

5. Review the report and issue CB certificate after it is qualified.

CB certification advantages

In the past, the vast majority of electronic and electrical products need to meet different regulations when entering various countries. It is difficult and time-consuming to obtain product safety certification from various countries. But now relying on CB system, manufacturers can obtain safety certification from 54 countries at one time, and truly realize one test to meet a variety of test needs.

Manufacturers that have obtained CB certificates can greatly reduce costs, energy and time when applying for other certifications.

1. The CB test report obtained by the enterprise can be easily converted into certification marks such as VDE, GS, GOST-R, SASO, and Australian RCM

2. CB test report can be easily converted to China CCC certification or voluntary certification

3. Obtaining CB certification is conducive to being directly recognized by many countries, such as Southeast Asian countries. CB certification inspection standard for battery products: iec62133:

"Safety requirements for single battery (cell) and portable cell of battery pack containing alkaline or non acid electrolyte and battery manufactured by them and portable applications"
