un38.3 is the lithium battery safety performance test report, according to various standards at home and abroad for all kinds of batteries to carry out a full set of safety performance tests, for all battery manufacturers to ensure product quality and safety, improve the export capacity in line with various standards. un38.3 refers to Article 38 of the Manual of Tests and Criteria prepared by the United Nations Committee of Experts on the Transport of Dangerous Goods on the testing of lithium batteriesSection 3 is for the detection of lithium battery products. That is, before the lithium battery is transported, it must pass the high simulation, high and low temperature cycle, vibration test, impact test, 55 external short circuit, impact test, overcharge test, forced discharge test, mainly used to simulate the environment of air transportation and possible dangerous situations. So as to ensure the safety of lithium battery transportation. In order to ensure the safety of air transportation and meet the needs of customers for the transportation of goods containing lithium batteries, UN383. The test report is a mandatory test item. This report can be provided by a third-party testing agency designated by the Civil Aviation Administration, or it can be provided by the battery manufacturer with testing capabilities.
One: un383. The range of testing products includes the following products:
1.All kinds of lead-acid batteries (such as lead-acid batteries for automobile starting, stationary lead-acid batteries, small VRLA batteries, etc.)
2.Various power secondary batteries (such as batteries for power vehicles, batteries for electric road vehicles, batteries for power tools, batteries for hybrid vehicles, etc.)
3.Various mobile phone batteries (such as lithium-ion batteries, lithium polymer batteries, nickel-metal hydride batteries, etc.)
4.All kinds of small secondary batteries (such as laptop batteries, digital camera batteries, camera batteries, various cylindrical batteries, wireless communication batteries, portable batteries, CDs and batteries, etc.)
5.Various galvanic batteries (such as alkaline zinc-manganese batteries, lithium-manganese batteries, etc.)
un38.3. Certification test passing standards.
1.t.1 - t.4. No leakage, no exhaust, no disintegration, no rupture, no fire, and the open circuit voltage is not less than 90% before the test.
2. t.5 â t.6. The surface temperature does not exceed 170, and there is no disintegration, no cracking, and no fire within 6 hours of the test.
3. t.7 â t.8 No disintegration and no fire within 7 days after the test.
un38.3. Packaging requirements and conditions.
One: Limitation of lithium content.
For lithium metal or lithium alloy primary batteries, the lithium content shall not exceed 1g;The equivalent content of lithium in lithium-ion primary batteries shall not exceed 15G Note: Primary batteries are also known as cells. 2.The total lithium content of lithium metal or lithium alloy batteries shall not exceed 2g, and the equivalent lithium content of lithium-ion batteries shall not exceed 8g. Note: The above "lithium content" refers to the amount of lithium metal on the cathode of a lithium metal or lithium alloy battery. For lithium-ion batteries, the "lithium equivalent content" is calculated in grams as 03 times a h. For example, a mobile phone lithium-ion battery has a rated capacity of 800 mAh (800 mAh) and its "lithium equivalent content" is: 030.8 (ampere-hour) = 024 gă
2. Meet the United Nations testing requirements: Through testing, each galvanic cell and battery pack meets Section 38 of the United Nations Manual of Tests and Criteria for the Transport of Dangerous GoodsAll requirements of Article 3.
Three: packaging requirements.
1.Unless installed in a device such as a mobile phone, camera, walkie-talkie, laptop, etc. The battery and galvanic battery must be packed separately to prevent short circuits and packed with a firm outer packaging.
2.Unless installed in the device, if each package contains more than 24 primary cells or 12 battery packs, it must also meet the following requirements:
1) Each package must be marked with lithium batteries and special measures to be taken when the packaging is damaged.
2) Each shipment must be accompanied by a document stating the special measures to be taken when the package contains lithium batteries and the package is damaged.
3) Each package must be able to withstand 12 meters drop test in any direction, do not damage the battery or cell battery inside the package, do not change the position of the battery, so that the battery and the battery (or primary battery and primary battery) are in contact with each other, and no battery leaks out of the package.
4) If the batteries are shipped separately, the gross weight of each package must not exceed 10kg.
Four: label and outer box label requirements.
The label must be square, with the outermost circle being a dotted box and the dotted frame being a clipping line, placed at a 45-degree angle (diamond).
MSDS (Material Safety Data Sheet) is a Safety Data Sheet for Chemicals or Safety Data Sheets for Chemicals. It is a document 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 the possible harm to the health of users (such as carcinogenicity, teratogenicity, etc.). One of the documents required for the export of lithium batteries. The following documents are generally required for battery export: UN383. Test report, test summary, MSDS English version, sea and air transport certificate.
un38.3. The testing and certification process is roughly as follows:
1.Fill out the application form.
2.Fill out the Power of Attorney, Lithium Battery Shipping Statement, and accompanying documents.
3.Provide battery packaging**, battery specifications and other documents.
4.Sample test.
5.A draft report is issued for confirmation.
6.Application for appraisal.
7.Publish the report.
The testing and certification cycle is generally 3-4 weeks. Lithium batteries
