What is UN38 3 test?

What is UN38 3 test?

UN38. 3 is the prevailing United Nations standard that lithium batteries must meet to receive certification for safe transport. The U.S. Department of Transportation and many international regulatory bodies require lithium batteries are certified to UN38. 3 prior to transport.

What is UL1642 certification?

UL1642 certification requirements cover rechargeable lithium-ion batteries for use as a power supply in the products. UL1642 certification requirements cover user-replaceable lithium-ion batteries that contain 4.0g or less of metallic lithium-ion with not more than 1.0g of metallic lithium in each electrochemical cell.

Which certification is required for battery pack?

UN/DOT. In order to ship ANY lithium batteries products via air freight, the UN 38.3 test must be passed by the battery packs. New regulations were passed in 2016 that tighten requirements for shipments of lithium products and that forbid lithium batteries to be shipped on passenger aircraft.

Is UL2054 mandatory?

Although UL2054 is not a mandated test for products shipped into the US, it is often mandated by US end device standards and it is a pretty severe test as it requires a single fault to be applied on the battery pack. The fault is applied to a non-UL rated component.

What is the purpose of the UN 38.3 battery test report?

UN/DOT 38.3 testing helps ensure the safety of lithium ion or lithium metal batteries during shipping. The transport of lithium batteries is subject to national and international regulations as detailed by the UN (United Nations) in the U.N.

Does UN38 3 expire?

All UN38. 3 test reports for lithium batteries must have the CNAS stamp on it before the lab can issue air/sea Safe Transportation Certificate. The air / sea Safe Transportation certificates is valid up to December 31 of the issuing year. It will automatically expire after December 31 of each year.

Is ul1642 mandatory?

UL is short for Underwriters Laboratories Inc. UL certification is a non-compulsory certification in the United States, mainly testing and certification of product safety performance, and its certification scope does not include the product’s EMC (electromagnetic compatibility) characteristics.

Are batteries UL certified?

Safety testing and certification utilizing application-based standards and local country marks. Traditionally, battery cells have been certified to UL 1642, the Standard for Lithium Batteries. Widely known to apply to lithium-ion batteries, this Standard focused on portable consumer applications.

What is a battery certificate?

Battery certification is a somewhat time consuming measure yet is nevertheless essential to assist with the marketing of battery powered equipment, but more than that, it is a quality guarantee and a confirmation that the battery complies with technical expectations.

What IEC 61960?

IEC 61960-4:2020 specifies performance tests, designations, markings, dimensions and other requirements for coin secondary lithium cells and batteries for portable applications and backup power supply such as memory backup applications.

What is un testing?

The UN performance tests are based on the degree of hazard posed by the proposed materials to be packaged which are also assigned to a specific Packing Group. The purpose of the tests is to approve a design to the Packing Group level of performance.

What are the test items of ul 1642 certification?

All Test Items of UL 1642 Certification T.10 Short-Circuit Test T.11 Abnormal Charging Test T.13 CrushTest T.14 ImpactTest T.15 Shock Test T.16 Vibration Test T.17 Heating Test T.18 Temperature Cycling Test T.19 Low Pressure (Altitude Simulation) Test

What is the difference between UN 383 and UL 2054?

UN 38.3 transportation testing (see previous section) is an integral requirement, but does not need to be repeated. Compared to the requirements of UN 38.3, these tests are relatively easy to pass. Compliance with the requirements of UL 2054 is mandated by a number of U.S. end device standards.

Why do lithium batteries fail to pass the un3813 test?

The previous test may have a negative impact on the next test, resulting in failure to pass the test. If the lithium battery submitted for inspection is tested for T1 → T5 in the UN 38.3 standard, there will be one item unqualified. Enterprises need to re-test UN3813 standard after process improvement, which will greatly extend the testing cycle.

What is the T1 → T5 test in the un3813 standard?

However, the T1 → T5 test in the UN3813 standard tests the same sample in sequence. The previous test may have a negative impact on the next test, resulting in failure to pass the test. If the lithium battery submitted for inspection is tested for T1 → T5 in the UN 38.3 standard, there will be one item unqualified.
