UN38.3 is a provision in Section 3 of Chapter 38 of the United Nations "Handbook of Tests and Standards for the Transport of Dangerous Goods". In 2003, the United Nations approved the test requirements for safe transportation of li ion batteries first proposed by the Department of Transportation of the United States and officially added li ion battery products to Section 3 of Chapter 38 of the Orange Book. In 2005, the Operation Regulations Department of Air China Cargo Co., Ltd. issued the "Rechargeable Lithium Batteries as Nondangerous Goods Transport Regulations (interim)". As the operation specification of Air China Cargo for air transportation of li ion batteries, it opens the first chapter about li ion batteries UN38.3 in China. The latest UN38.3 is the first revision of the sixth edition ST/SG/AC.10/11/Rev.6/Amend.1.
The standard has been widely accepted by the member states of the United Nations, and has also been used by the International Air Transport Association (IATA), the International Civil Aviation Organization (ICAO), and the International Maritime Organization (IMO) as a reference basis for the development of battery transportation requirements in their respective fields. It has become the de facto standard for aviation, maritime, railway, and road transportation worldwide.
IEC is the International Electrotechnical Commission, which has many standardization organizations under its jurisdiction. The technical organizations related to li ion batteries mainly include IEC/TC21, IEC/SC21A, IEC/TC35, IEC/TC108, etc. The specific division of function is as follows. IEC/TC21 (Technical Committee for Batteries and Battery Packs) for all secondary batteries related to li ion batteries, is mainly responsible for the formulation and revision of li ion battery cell performance and safety standards for electric road vehicles. IEC/SC21A (Sub-Technical Committee for Alkaline and Non-Acid Batteries) is responsible for the revision of all standards for all cells of li ion batteries and battery packs except for electric road vehicles, including performance, specifications, and safety standards of portable equipment, industrial equipment, field vehicles, as well as li ion battery cells and battery packs for UPS. IEC/TC35 (Previous Battery Technical Committee) is responsible for the formulation of galvanic battery standards, and is responsible for the safe transportation standards of li ion batteries together with IEC/SC21A. IEC/TC108 (Technical Committee on the Safety of Electronic Products) is responsible for the formulation of supplementary safety requirements related to the safety of li ion batteries used in electronic products, such as the flame retardant rating of battery pack casings, charge and discharge management of host equipment. IEC/TC69 (Technical Committee for Electric Road Vehicles and Electric Trucks). In 1997, IEC/TC21 and TC69 established 3 joint working groups, and JWG69Li led by TC21 focused on li ion batteries for automotive use.
ISO(International Organization for Standardization) is a level A advisory organization of the United Nations Economic and Social Council and a comprehensive level(the highest level) advisory organization of the Trade Development Council. As a global non-governmental organization, it is currently the largest and most authoritative international standardization specialized organization in the world. ISO's technical work is mainly carried out through its technical committee. TC22 is the code name of the International Organization for Standardization/Road Vehicle Technical Committee, which has 19 sub-technical committees. SC37 is the sub-technical committee of electric vehicles with li ion batteries.
IEEE (Institute of Electrical and Electronics Engineers) is an international association of electronic technology and information science engineers. It is currently the largest non-profit professional technical society in the world, which covers more than 160 countries. IEEE is dedicated to the development and research of electrical, electronic, computer engineering and science-related fields. It has developed more than 900 industry standards in the fields of space, computers, telecommunications, biomedicine, power and consumer electronics. Also, it is a current international academic organization with greater influence.
There are national mandatory standards, national recommended standards and various industry standards for li ion batteries in China, including battery materials, battery cell manufacturing, as well as recycling of PACK and li ion batteries.
The formulation and revision of standards for li ion batteries are very active in China, which is also the need for the market to continuously improve the safety performance of li ion batteries. What is more, this also creates more serious challenges for lithium ion battery manufacturers to constantly improve their design, production and testing processes.
