▍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.
International Maritime Dangerous Goods (IMDG) is the most significant rule of maritime dangerous goods transport, which plays an important role in safeguarding the transport of shipborne dangerous goods and preventing the pollution of marine environment. International Maritime Organization (IMO) makes an amendment on IMDG CODE every two years. The new edition of IMDG CODE (41-22) will be implemented from January 1st, 2023. There is a 12-month transitional period from January 1st, 2023 to December 31st, 2023. The following is the comparison between IMDG CODE 2022 (41-22) and IMDG CODE 2020 (40-20).2.9.4.7 : Add the no-testing profile of the button battery. Except for the button batteries installed in the equipment (including the circuit board), the manufacturers and the subsequent distributors whose cells and batteries are produced after June 30, 2023 shall provide the testing profile regulated by Manual of Tests and Standards-Part III, Chapter 38.3, Section 38.3.5. Part P003/P408/P801/P903/P909/P910 of the package instruction adds that authorized net mass of the pack can surpass 400kg.Part P911 of the packing instruction (applicable to damaged or deficient batteries transported as per UN 3480/3481/3090/3091) adds new specific description of package usage. Package description shall at least include the following: labels of the batteries and the equipment in the pack, maximum quantity of the batteries and maximum amount of the battery energy and the configuration in the pack (including the separator and the fuse used in performance verification test). Additional requirements are the maximum quantity of the batteries, the equipment, total maximum energy and configuration in the pack (including the separator and the fuse of the components).
