▍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.
Life cycle assessment (LCA) is a tool to measure the consumption of energy source and environmental impact of a product, production craft. The tool will measure from raw material collection to production, transporting, usage, and eventually to final disposal. LCA is founded since 1970s.The Society of Environmental Toxicology and Chemistry (SETAC) defines SETAC as a method to assess how products, production and actions impact on environment by evaluate raw materials usage, energy consumption and waste release.In 1997, ISO issued ISO 14000 series, and defined LCA as the compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle. The environmental impact includes resources usage, human health and ecology. ISO 14040 defines the principal and framework, and ISO 14044 defines requirements and guidance.LCA evaluation contains 4 phases:
1)goal and scope. This is about the purpose of research, the boundaries of the system, what unit is chosen to use, and the requirement on data.
2)Inventory analysis. This involves data collection and disposal.
3)Impact assessment. This is to analyze the elements that impact environment.
Interpretation. This is to conclude the assessment and analyze the result.
