The Chinese Model Approval is abbreviated as SRRC certification, which is a national compulsory certification designed to distinguish between the civilian band and the military band in the wireless band. It is the technical management of the spectrum parameters and technical indicators of the radio transmission equipment before it is put into use in the development, production, import, and purchase links. Since June 1, 1999, the Ministry of Information Industry (MII) of China has mandated that radio component products sold and used within the country must obtain radio model approval. Domestically produced, sold and used radio transmission equipment must be type approved, and the approval certificate and type approval code must be issued. The type approval code must be indicated on the label of the factory equipment. The State Radio Monitoring Center (SRMC) of China, formerly known as the State Radio Regulation Committee (SRRC), is the only organization in Mainland China authorized to test and certify radio model approval requirements.

The \"KC\" logo means \"Korea Certification\". The thirteen statutory mandatory signs currently used in South Korea will all be unified into the country’s unified signs. This will simplify the certification process, reduce the cost of manufacturer certification, and enable the KC logo to develop into a world-recognized brand.

Multimedia all-in-one integrates infrared touch technology, intelligent office software, multimedia network communication technology, high-definition flat panel display technology and other technologies, and integrates projector, electronic whiteboard, computer (optional), TV, touch function, etc. A multi-functional interactive device that integrates a variety of devices to upgrade the traditional display terminal to a full-featured human-computer interaction device. According to the functional description and hardware structure of the all-in-one machine, three certification product categories are mainly involved: 0808, 0901 and 0903. All-in-one machines generally mainly consider 0901 and 0903 categories. When the product has display and TV functions, dual standards need to be considered, that is, to apply for CCC certification ?according to 0808 and 0903, and the test is tested according to 0808 and 0903 standards. A report is issued and a certificate is issued ( Generally, the certificate is issued according to category 0903).

There are many different technologies and media in the air purifier, which enable it to provide users with clean and safe air. Because the air purifier itself is closely related to our lives. Therefore, the safety of the product itself is the first thing consumers need to consider, and the other is its efficiency and effectiveness in purifying the air. Nowadays, domestic air purifiers have gradually moved to the stage of the international market with the continuous improvement of I art. However, if you want to successfully enter the EU market for sales, how to apply for the CE certification of air purifiers?

KC ?(Korea Certification) certification, formerly known as EK certification, is the Korean electrical and electronic appliance safety certification system, that is, KC mark certification, which was established by the Korea Institute of Technology and Standards (KATS) in 2009 in accordance with the Electrical Appliances Safety Management Act The mandatory safety certification system implemented on January 1.

CCC certification materials are roughly divided into 3 parts, the first part: application materials; the second part: sample testing materials; the third part: factory audit materials

In order to ensure the safety of air transportation and meet the customers’ demand for the transportation of goods containing lithium batteries, in accordance with the relevant provisions of the International Air Transport Association \"Dangerous Goods Regulations\", the operating specifications for rechargeable lithium batteries, namely UN38.3 (UNDOT) testing, have been formulated . According to the requirements of civil aviation regulations, airlines and airport cargo receiving and transportation departments should review the transportation documents of lithium batteries. The most important thing is the UN38.3 safety test report of each type of lithium battery. The report can be provided by a third-party testing agency designated by civil aviation, or by a battery manufacturer with testing capabilities. If this test report cannot be provided, civil aviation will prohibit air transportation of lithium batteries.

Usually when many people do battery testing, they confuse UN38.3 and MSDS or think that they are the same certification, which has a great impact on the testing. MSDS is a chemical safety technical specification, a document for the composition and emergency treatment of lithium batteries, and UN38.3 is a safety test for lithium batteries. Because lithium batteries are shipped by air, it is often required to provide UN38.3 and MSDS together, so many people mistakenly think that UN38.3 is MSDS.
