I. Introduction to UN38.3 certification
UN38.3 refers to the Manual of Tests and Criteria prepared by the United Nations Committee of Experts on the Transportation of Dangerous Goods (Manual of Tests and Criteria) on lithium batteries in the test of section 38.3.
UN38.3 is a battery safety performance test report, and based on a variety of standards at home and abroad on a variety of models of batteries to carry out a full set of safety performance testing for the battery manufacturers to ensure the safety of product quality and compliance with various standards to improve export capacity.
1) UN38.3 test is to ensure that lithium batteries can be safely transported by air, sea and land by mandatory testing.
2) General Administration of Civil Aviation to the air transport companies issued a "lithium battery air transport specifications", clearly require lithium batteries before air and sea transport must be through the CNAS accredited laboratory for UN38.3 test provisions, the airlines must be in the receipt of lithium batteries UN38.3 qualified report and transport identification certificate under the premise, before receiving and transporting the lithium batteries.
Two, why do UN38.3?
Because cell phones, laptops and other lithium batteries are in the transportation process there is a certain degree of danger, so China International Cargo Airlines Ltd. announced as a non-dangerous goods transportation of rechargeable lithium batteries, the specification specification clearly states that each type of primary cells and batteries, need to be tested to prove that comply with the United Nations transport of dangerous goods, the test and standards manual part 3 Manual of Tests and Criteria for the Transportation of Dangerous Goods, Part 3, paragraph 38.3, that is, UN38.3.
