Recently, un38.3 was updated to seventh edition. Some of the content of Chapter 38.3 has been revised in two places:
In the test summary: 38.3.5(f). )(ii) the original “Quality (mass)” is replaced by “mass of the battery or battery pack”
38.3.5(f)(v) The “model” d The original is replaced by “battery or battery pack model, if the subject of the test situation summary is For a product containing batteries and battery packs, indicate the model number of the product. It has been edited and shown here for accuracy and clarity.
The title of chapter 38 modifies the original “Related to category 9” by “Related to the transport of substances and objects of category 9”.
Many other parts of the chapter 38 are originally The content "Categorie 9" is replaced by "Transport category 9"
The difference between lithium battery un38.3 and msd
According to the requirements of the regulations of the Civil aviation, all batteries. For air transport of products containing batteries, a UN38.3 air transport certificate is required. The most important thing is that each model of UN38.3 must be applied for only one model. The designated civil aviation testing agency, the International Air Transport Association (IATA) (referred to as IATA), can also be provided by battery manufacturers with testing capabilities. If this test report cannot be provided. provided, civil aviation will prohibit the use of lithium batteries to be transported by air
For UN38.3 cargo air transportation certification and cargo navigation, the assessment certificate. of transport is only valid for the current year, that is to say it is valid until December 31e of this year. must be updated on January 1st each year!

Polymer What is the difference between UN38.3 certification of lithium batteries and IEC62133, and what standards are tested
Response to lithium battery testing and certification Shenzhen Plugs (ptl-global.com):
UN38.3 is a standard test. The full name can be found in section 38.3 of Part 3 of the "United Nations Manual of Tests and Standards for the Transport of Dangerous Goods" specially developed by the United Nations for the transport of dangerous goods, which requires that batteries lithium must pass the altitude simulation. , high and low temperature cycling, vibration testing, impact testing, 55℃ external short circuit, impact testing, overload testing and forced discharge testing can ensure the safety of the transport of lithium batteriesum. If the lithium battery is not installed with the device and each package contains more than 24 cells or 12 batteries, it must also pass the 1.2 meter free fall test.
MSDS (Material Safety Data Sheet) is the chemical safety data sheet, which can also be translated as chemical safety data sheet or chemical safety data sheet. It is used by chemical manufacturers and importers to clarify the physical and chemical properties of chemicals (such as pH value, flash point, flammability, reactivity, etc.) and possible damage to user health (such as carcinogenesis, teratogenicity, etc.) A document.
Whether lithium batteries are shipped by sea or air, a UN38.3 report and MSDS are required. It should be noted that UN38.3 must be tested by a qualified and designated third party testing company. The MSDS may be submitted to a third party for testing, or the factory may issue it itself.
Why air transport of lithium batteries requires UN38.3
Lithium polymer batteryUN38 certification .3 relates to battery transportation safety A standard that mainly tests safety issues that may arise during battery transportation to ensure battery transportation safety. The testing standard is UN38.3.
IEC62133 certification of lithium polymer battery is a certification for battery safety, a standard for testing the performance and life of batteries, and a test for the quality of batteries. Some batteries that are too bad will have a test. fails, if the test fails and the certificate cannot be issued, the manufacturer can only continue to test the product after rectifying it, then the certificate can be dissued if it passes the test. Generally, this report is required when leaving the EU, and it is also the standard when applying for CB and KC.
Lithium polymer battery, also known as lithium polymer battery, is a chemical battery. Compared with previous batteries, it has the characteristics of high energy, miniaturization and light weight.
Lithium polymer batteries have ultra-thin characteristics and can be made into batteries of different shapes and capacities to meet the needs of certain products. The theoretical minimum thickness can be up to 0.5 mm.
Basic Information
A general battery has three elements: a positive electrode, a negative electrode, and an electrolyte. The so-called lithium-polymer battery refers to a battery system that uses polymer materials in at least one or more of the three cells. In the systems oflithium polymer batteries, polymer materials are mainly used in the cathode and electrolyte.
The positive electrode material uses conductive polymers or inorganic compounds used in general lithium-ion batteries. The negative electrode often uses lithium metal or lithium carbon interlayer compounds, and the electrolyte uses solid or colloidal or organic polymer electrolytes. electrolyte. Since there is no excess electrolyte in lithium polymer, it is more reliable and stable.
What is UN38.3 lithium battery
In accordance with the requirements of civil aviation regulations, airlines and transport services Airport cargo collection and transportation must review the transport documents of lithium batteries. . The most important thing is the UN38.3 safety test report for each lithium battery model. THEReport may be provided by a third party testing agency designated by Civil Aviation,
International Air Transport Association (IATA)
or by a battery manufacturer with testing capabilities . If this test report cannot be provided, civil aviation will prohibit the transportation of lithium batteries by air.
