CTIA represents the Cellular Telecommunications and Internet Association, a non-profit private organization in the United States. CTIA provides an unbiased, independent and centralized product evaluation and certification for the wireless industry. Under this certification system, all consumer wireless products must pass the corresponding conformity test and meet the requirements of relevant standards before they can be sold in the North American communications market.
Provide a detailed step-by-step guide to the certification process：
A: The UN38.3 certificate or report is required for all battery cells
A: Yes, battery control label only.
A: Yes, certification is required in order
A: Need to include: model, nominal voltage, rated capacity, chemical system (name includes lithium ion or lithium polymer, name can be used), trademark or machine/battery seller name (generally the applicant).
A: CTIA's battery certification is currently a mandatory entry requirement for telecom operators in North America.
A: Yes, in addition to meeting the test, it is also required to conduct a factory audit of the cell manufacturer, that is, to audit the key processes of the cell production process and its quality control, quality system and technical capabilities.
A: For the cell, the test items include diaphragm performance, normal temperature/high temperature diaphragm shrinkage, electrode size, pole ear, insulation material application, additional insulation material application, cell exhaust device, avoid internal short circuit, insulation material location, heat abuse, lithium analysis and short circuit test of the cyclic cell and external short circuit of the temperature cycle cell, a total of 13 tests.
