UN38.3 is a test standard, which refers to the third part 38.3 of the \"Dangerous Goods Transport Test and Standard Manual\" specially formulated by the United Nations for the transportation of dangerous goods, which requires that lithium batteries must pass a high degree of simulation and high Low temperature cycle, vibration test, impact test, 55℃ external short circuit, impact test, overcharge test, forced discharge test can ensure the safety of lithium battery transportation. If the lithium battery and the equipment are not installed together, and each package contains more than 24 battery cells or 12 batteries, it must pass the 1.2-meter free drop test.

Plastics can be said to be the natural enemy of nature, but human society cannot leave plastics. Many products require large amounts of plastics. In order to reduce the harm of plastics to the human body and the pollution of nature, the EU ROHS test set up a research laboratory, and finally obtained the safety limit of plastics through repeated experiments. And take the limit as the plastic RoHS test instruction. Many countries in North America and Europe include RoHS in the product safety laws.

Stainless steel (Stainless Steel) is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water, or is stainless steel; and chemically resistant to chemical corrosion media (acid, alkali, salt, etc.) Corrosion steel is called acid-resistant steel. Stainless steel products are relatively common in our lives, and ROHS testing is required for such products to be sold in the EU. If the product is not certified for RoHS, it will cause an incalculable loss to the exporter, and may cause no one to care about your product; but if it enters the market and is found to have not done relevant testing, it will also cause significant losses to the company!

The main content of the reach certification is to prove that textiles and clothing do not contain harmful chemical substances. Therefore, all textiles and garments produced in the EU or imported into the EU market must pass the registration, inspection and approval of the content of hazardous chemical substances. Once the content exceeds the prescribed content, they cannot be sold on the EU market.

SRRC certification (SRMC certification) is a mandatory 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 Radio Type Approval Certification (Radio Type Approval Certification).

Products made in China need to be exported to other countries around the world, and they usually have to meet local safety certification standards before they can be sold in the region. Because each country has its own national conditions, different geographical environment, national culture, living habits and national protection awareness, this has prompted most countries to formulate a set of product standards suitable for their national conditions to protect their citizens. Safety and environment. In this way, as long as the products are exported to different countries, the standard requirements are different. Therefore, a third-party testing agency has emerged to conduct product testing and certification in a fair, authoritative and objective way to evaluate whether the exporting country meets the standard requirements.

RoHS certification is the \"Directive on Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment\", which stipulates the restriction of lead, cadmium, mercury, hexavalent chromium, polybrominated diphenyl ethers, polybrominated biphenyls and RoHS2.0 in electrical and electronic products A total of 10 hazardous substances such as DEHP, DBP, BBP, and DIBP.

CCC certification is a national compulsory product certification, CQC certification is a national voluntary product certification, also known as logo certification, and CQC is the abbreviation of China Quality Certification Center. The main difference between the two is that CCC certification is compulsory certification, and CQC is voluntary certification. In addition, there are differences in certification classification and product coverage.
