Project Instruction

The technical difference between JIS C 62133-2 and IEC 62133-2,
Iec 62133,

▍Certification Overview

Standards and Certification Document

Test standard: GB31241-2014: Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification document: CQC11-464112-2015: Secondary Battery and Battery Pack Safety Certification Rules for Portable Electronic Devices

 

Background and Date of implementation

1. GB31241-2014 was published on December 5th, 2014;

2. GB31241-2014 was mandatorily implemented on August 1st, 2015. ;

3. On October 15th, 2015, Certification and Accreditation Administration issued a technical resolution on additional testing standard GB31241 for key component “battery” of the audio and video equipment, information technology equipment and telecom terminal equipment. The resolution stipulates that the lithium batteries used in the above products need to be randomly tested as per GB31241-2014, or obtain a separate certification. 

Note: GB 31241-2014 is a national compulsory standard. All the lithium battery products sold in China shall conform to GB31241 standard. This standard will be used in new sampling schemes for national, provincial and local random inspection.

▍Scope of Certification

GB31241-2014 Lithium ion cells and batteries used in portable electronic equipment―Safety requirements
Certification documents is mainly for mobile electronic products that are scheduled to be less than 18kg and can be often carried by users. The main examples are as follows. The portable electronic products listed below do not include all products, so products not listed are not necessarily outside the scope of this standard.

Wearable equipment: Lithium-ion batteries and battery packs used in equipment need to meet standard requirements.

Electronic product category

Detailed examples of various types of electronic products

Portable office products

notebook, pda, etc.

Mobile communications products mobile phone, cordless phone, Bluetooth headset, walkie-talkie, etc.
Portable audio and video products portable television set, portable player, camera, video camera, etc.
Other portable products electronic navigator, digital photo frame, game consoles, e-books, etc.

▍Why MCM?

● Qualification recognition: MCM is a CQC accredited contract laboratory and a CESI accredited laboratory. The test report issued can be directly applied for CQC or CESI certificate;

● Technical support: MCM has ample GB31241 testing equipment and is equipped with more than 10 professional technicians to conduct in-depth research on testing technology, certification, factory audit and other processes, which can provide more accurate and customized GB 31241 certification services for global clients.

From the JIS standard website, we noticed that JIS C 62133-2 “Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications-Part 2: Lithium systems” was released on Dec. 21st 2020. This standard was established according to not only IEC 62133-2 2017, but also the Attached 9-Lithium Battery in the Electrical Appliance and Material Safety Law ”DENAN”, especially the testing items which are mainly from the content of DENAN Attached 9.
The mainly technical differences between JIS C 62133-2 and IEC 62133-2 are shown below:
From the above changes we can see that JIS C 62133-2 has adopted both the content of IEC 62133-2 and PSE Appendix 9. But until now, METI has made it clear that PSE has not adopted the standard of JIS C 62133-2, and JIS C 8712 is still valid. However for the PSE certificate, we still recommend the batteries are tested in accordance with Appendix 9 of the “Electrical Safety Law Denan”.
