SRRC is a compulsory certification requirement of the National Radio Regulatory Commission. Since June 1, 1999, the Ministry of Information Industry (MII) of China has mandated that all radio component products sold and used in China must obtain a radio model Radio Type Approval Certification (Radio Type Approval Certification).

According to the \"Regulations on the Administration of Imported Radio Transmission Equipment\" and the \"Regulations on the Administration of the Production of Radio Transmission Equipment\", in order to strengthen the management of the import and production of radio transmission equipment, all radio transmission equipment exported to the People’s Republic of Radio transmission equipment produced (including trial production) must be issued with a \"Radio Transmission Equipment Type Approval Certificate\" after type approval (SRRC) for its emission characteristics. The type approval code must be indicated on the label of the factory equipment.

The full name of 3C certification is \"China Compulsory Certification\", the English name is China Compulsory Certification, and the English abbreviation is CCC. It is a product conformity assessment system implemented by the Chinese government in accordance with laws and regulations to protect consumers\' personal safety and national security, strengthen product quality management. It should be noted that the 3C mark is not a quality mark, it is a basic safety certification. As the three-in-one \"CCC\" certification of National Safety Certification (CCEE), Import Safety Quality Licensing System (CCIB), and China Electromagnetic Compatibility Certification (EMC), it is an advanced international standard by the General Administration of Quality Supervision, Inspection and Quarantine and CNCA Signs are of irreplaceable importance.

The CB certification certificate and the corresponding CB test report together constitute a pass. The manufacturer can apply for global certification from any national certification body in the country or region participating in the CB system, and it is usually exempted or reduced to send samples and tests, no longer needed Carrying out additional tests will greatly shorten the product\'s market entry cycle, reduce costs and accelerate product exports. The CB certification provides evidence that a representative sample of the product has successfully passed the test, showing that it meets the requirements of the relevant IEC standards. If you want to sell battery products in some countries that do not have its own certification, you can use CB certification to show that the product has obtained international certification or approval.

It will be fully implemented before March next year.

The Wi-Fi module, also known as the serial port Wi-Fi module, belongs to the transmission layer of the Internet of Things. Its function is to convert the serial port or TTL level into an embedded module that conforms to the Wi-Fi wireless network communication standard. The built-in wireless network protocol IEEE802.11b.gn Protocol stack and TCP/IP protocol stack. Traditional hardware devices embedded in Wi-Fi modules can directly use Wi-Fi to connect to the Internet, which is an important part of realizing wireless smart home, M2M and other Internet of Things applications. The product needs to apply for the SRRC certification established by China for radio because of its wireless transmission function.

RoHS is the abbreviation of \"The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment\". It is the European Union\'s regulation on electronic and electrical products and related chemical substances.

The \"Radio Law\" requires the type approval of designated radio equipment (that is, the certification of compliance with technical regulations). TELEC certification is mandatory, and the certification body is a registered certification body recognized by MIC in the scope of designated radio equipment. TELEC (Telecom Engineering Center) is the main registered certification body for conformity certification of radio equipment in Japan.
