Introduction to the UN38.3 certification
United Nations Recommendations on Transport of Dangerous Goods, Manual
of Tests and Criteria, Section 38.3 "- DO38.3 certification. To ensure the safety of air transport and to meet customer demand for
the transport of lithium battery cargo, according to the IATA "dangerous
goods rules" the relevant provisions of the development of rechargeable
lithium battery operating specifications, that UN38.3 (UNDOT) test. According
to the requirements of civil aviation regulations, airlines and airport
cargo handling departments should deal with lithium battery transport
documents review, the most important is the type of lithium battery
UN38.3 security test report. The
report may be provided by a third party testing agency designated by
the Civil Aviation Authority (such as Deppra Testing) or by a battery
manufacturer with detection capability. If you can not provide this test report, civil aviation will prohibit lithium batteries for air transport. UN38.3
refers to Section 3 of the United Nations Handbook on Transport Tests
and Criteria for the Transport of Dangerous Goods specially developed
for the transport of dangerous goods, paragraph 38.3, that requires the
use of a high degree of simulation, high and low temperature cycling,
vibration tests ,
Impact test, 55 ℃ outside the short circuit, impact test, overcharge
test, forced discharge test, in order to ensure the safety of lithium
battery transport. If the lithium battery and equipment are not installed together, you must also pass the 1.2 m free drop test.
UN38.3 certification mark
UN38.3 certified product range
1. Various power lithium secondary batteries (such as power car
batteries, electric road vehicles with batteries, power tools with
batteries, hybrid batteries, etc.) 2. A variety of mobile phone batteries (such as lithium-ion batteries, lithium polymer batteries, etc.) 3. A variety of small secondary batteries (such as laptop
batteries, digital camera batteries, camera batteries, a variety of
cylindrical batteries, wireless communications batteries, portable DVD
batteries, CD and MP3 player batteries, etc.) 4. A variety of primary batteries (such as lithium manganese batteries, etc.)
UN38.3 test items
T.1 height simulation test T.2 Thermal test T.3 Vibration test T.4 impact test T.5 external short circuit test T.6 collision test T.7 overcharge test T.8 forced discharge test Determine the test eligibility criteria
A. T.1 - T.4 no mass loss, no leakage, no exhaust, no disintegration,
no rupture, no fire, open circuit voltage is not less than 90% B. T.5 - T.6 surface temperature does not exceed 170 ℃, 6 hours after the test without disintegration, no rupture, no fire C. T.7 - T.8 test 7 days without disintegration, no fire Packaging requirements and conditions Disposable
lithium batteries and lithium batteries can be transported by
non-restrictive items (non-hazardous) if all of the following conditions
are met. If any of the following conditions are not met, the UN3090 or UN3091 shall be required for the transport of dangerous goods:
(A), restrictions on lithium content
1, for lithium metal or lithium alloy battery, lithium content should
not exceed 1g; for lithium-ion battery its rated watts hours no more
than 20Wh. Note: The original battery is also known as the battery cell. 2, for lithium metal or lithium alloy battery, the total lithium
content of not more than 2g, for lithium-ion battery rated watts less
than 100Wh. Note: The above-mentioned "lithium content" refers to the amount of
lithium metal on the anode of a lithium metal or lithium alloy battery. For
lithium metal or lithium alloy batteries or batteries, the "lithium
equivalent content" in grams is calculated by multiplying by 0.3 times
the rated capacity of the ampere hours. For example: a cell phone lithium-ion battery rated capacity is 800mah
(800 milliampere hours), then the "lithium equivalent content" is: 0.3 X
0.8 (ampere hours) = 0.24 grams. (B), meet the UN test requirements
Each type of primary battery and battery has been tested to
demonstrate compliance with all requirements of Section 3, Section 3, of
the United Nations Handbook on the Transport Test and Criteria for
Dangerous Goods.
(C), packaging requirements
1, unless installed in the equipment (such as installed in mobile
phones, cameras, walkie-talkie, laptop, etc.), the battery and the
original battery must be individually packaged to prevent short circuit,
and installed in a solid outer packaging. 2, unless installed in the equipment, each package if more than 24
original batteries or 12 batteries, must also meet the following
requirements: 1) Each package must be marked with a special measure that should be taken when the lithium battery and the package are damaged. 2) Each ticket must have a random file to illustrate the package
containing lithium batteries and packaging damage should be taken when
the special measures. 3)
Each package must be able to withstand any orientation of the 1.2m drop
test without damaging the battery or battery in the package and does
not change the location of the battery so that the battery and battery
(or the original battery and the original battery) Contact, no battery leaked from the package. 4) If the battery is shipped separately, the gross weight of each package shall not exceed 10kg.
UN38.3 test version revised to version 6
Section
3 of the United Nations Handbook on the Transport of Dangerous Goods
and Standards Manual, Section 38.3 (UN38.3) Rev.6, has been released,
which will replace the current version of Rev.5, which requires a
greater detection of lithium batteries Changes are mainly as follows:
Variation 1: In Section 38.3.4.5.2, the ambient temperature requirements for the T5 test items have been changed.
Variation 2: In Section 38.3.4.4.2, the peak acceleration value of the
acceleration shock is modified. The small battery exceeds 4.48Kg, the
peak acceleration will be less than 150gn, the large battery will exceed
12Kg and the peak acceleration will be less than 50gn.
Note:
In Section 38.3.4.2.2, the high temperature storage temperature of test
item T2 has been changed from 75 ± 2 ° C to 72 ± 2 ° C. For more information, please contact Deppra.
