▍What is CTIA CERTIFICATION?

CTIA, the abbreviation of Cellular Telecommunications and Internet Association, is a non-profit civic organization established in 1984 for the purpose of guaranteeing benefit of operators, manufacturers and users. CTIA consists of all U.S. operators and manufacturers from mobile radio services, as well as from wireless data services and products. Supported by FCC (Federal Communications Commission) and Congress, CTIA performs a large part of duties and functions that were used to be conducted by the government. In 1991, CTIA created an unbiased, independent and centralized product evaluation and certification system for wireless industry. Under the system, all wireless products in consumer grade shall take compliance tests and those complying with the relevant standards will be granted to utilize CTIA marking and hit store shelves of North American communication market.

CATL (CTIA Authorized Testing Laboratory) represents labs accredited by CTIA for testing and review. Testing reports issued from CATL would be all approved by CTIA. While other testing reports and results from non-CATL will not be recognized or have no access to CTIA. CATL accredited by CTIA varies in industries and certifications. Only CATL which is qualified for battery compliance test and inspection has access to battery certification for compliance to  IEEE1725.

▍CTIA Battery Testing Standards

a) Certification Requirement for Battery system Compliance to IEEE1725— Applicable to Battery Systems with single cell or multiple cells connected in parallel;

b) Certification Requirement for Battery system Compliance to IEEE1625— Applicable to Battery Systems with multiple cells connected in parallel or in both parallel and series;

Warm tips: Select above certification standards properly for batteries used in mobile phones and computers. Do not misuse IEE1725 for batteries in mobile phones or IEEE1625 for batteries in computers.

▍Why MCM？

● Hard Technology: Since 2014, MCM has been attending battery pack conference held by CTIA in US annually, and is able to obtain latest update and understand new policy trends about CTIA in a more prompt, accurate and active way. 

●Qualification: MCM is CATL accredited by CTIA and is qualified to perform all processes related to certification including testing, factory audit and report uploading.

The test requirements of UL 9540A derives from UL 9540, whose purpose is to evaluate the safety of the final product during installation and use and the exemption or relaxation of installation conditions through thermal runaway and heat spread tests(such as increasing the total capacity of energy storage system, reduce the installation distance, etc.). So the user of this report is the department or personnel authorized by the government in the place where the product is installed. Therefore, when conducting this test, the popularity or recognition of the report issuing agency is very important. As an international certification agency, TUV RH has high recognition in both Europe and North America, and is one of the organizations that manufacturers and factories highly trust.
China Tabaco issued Electronic Cigarette Management Regulation on March 11th 2022, and the rule, which has addressed that e-cigarette shall follow the mandatory national standards, was implemented on May 1st. The compulsory standard will come into force on October 1st 2022. Considering the implementation date of the Electronic Cigarette Management Regulation, there will be a transition period until September 30th. After the end of transition period, businesses around e-cigarette shall strictly follow the laws of Law of PRC on Tobacoo Monopoly, Regulation of implementing Law of PRC on Tobacoo Monopoly and Electronic Cigarette Management Regulation.
