  • International Maritime Dangerous Goods (IMDG) Code Special provisions 188
    According to UN Recommendations on the Transport of Dangerous Goods - Manual of Test and Criteria, lithium battery is classified as dangerous goods in class 9. However, in marine transport, if lithium cells and batteries meet the requirement in SP188, which means they are not subject to provisions of the test and criteria, then, they can be transported as Non-Dangerous Goods . Special provisions 188: (a)For a lithium metal or lithium alloy cell, the lithium content is not more than 1 g, and for a lithium-ion cell, the Watt-hour rating is not more than 20Wh. (b)For a lithium metal or lithium alloy battery, the aggregate lithium content is not more than 2 g, and for a lithium-ion battery, the watt-hour rating is not more than 100Wh. Lithium ion batteries subject to this provision shall be marked with the Watt-hour rating on the outside case, except those manufactured before 1 January 2009. (c)Each cell or battery is of the type proved to meet the requirements of each test in the Manual of Tests and Criteria, PartⅢ, sub-section 38.3. (d)Cells and batteries, expect when installed in equipment, shall be packed in inner packaging that completely enclose the cell or battery. Each cell or battery must be protected to prevent short circuits including protection against contact with conductive materials within the same packaging that could lead to a short circuit. The inner package must be packed in a strong outer packaging that is conforming to 4.1.1.1. 4.1.1.2 and 4.1.1.5. (e)As for cells or batteries that are installed in equipment shall be protected from damage and short circuit, and the equipment shall be equipped with an effective means of preventing accidental activation. When batteries are installed in equipment, the equipment shall be packed in strong outer packaging constructed of suitable material of adequate strength and design in relation to the packaging's capacity and its intended use unless the battery is afforded equivalent protection by the equipment in which it is contained. (f)Except for packages containing button cell batteries installed in equipment (including circuit boards), or no more than four cells installed in equipment or no more than two batteries installed in equipment, each package shall be marked. Lithium battery meet these condition should be ordered and transported as dangerous goods, but it can be exempted from requirements for packaging, stowage and isolation of dangerous goods. In summary, Lithium ion battery has passed UN38.3 test, lithium content is within required limit and the package is suitable, then it can be transported as non-dangerous good. (g)Except when batteries are installed in equipment, each package is capable of withstanding a 1.2 m drop test in any orientation without damage to cells or batteries contained therein, without shifting of the contents so as to allow battery to battery (or cell to cell) contact and without release of contents; (h)Except when batteries are installed in or packed with equipment, packages shall not exceed 30 kg gross mass. As used above and elsewhere in this provisions, the "lithium content" means the mass of lithium in the anode of a lithium metal or lithium alloy battery. UN Recommendations on the Transport of Dangerous Goods - Manual of Test and Criteria, Sub-section 38.3  Test content Series Standard requirement Altitude Simulation 38.3.4.1 Cell and battery shall no leaking, venting, disassembly, rupture or fire. The open circuit voltage of test cell or battery shall not be less than 90% of the pre-test voltage after testing. The voltage requirements do not apply to test cell and battery in a fully discharged state. Thermal Test 38.3.4.2 Cell and battery shall no leaking, venting, disassembly, rupture or fire. The open circuit voltage of test cell or battery shall not be less than 90% of the pre-test voltage after testing. The voltage requirements do not apply to test cell and battery in a fully discharged state. Vibration 38.3.4.3 Cell and battery shall no leaking, venting, disassembly, rupture or fire during and after the test. And the open circuit voltage of each test cell or battery in the third perpendicular mounting positions shall not be less than 90% of the pre-test voltage after test. The voltage requirements do not apply to tested cell and battery in a fully discharged state. Shock 38.3.4.4 Cell and battery shall no leaking, venting, disassembly, rupture or fire. The open circuit voltage of test cell or battery shall not be less than 90% of the pre-test voltage after testing. The voltage requirements do not apply to test cell and battery in a fully discharged state. External Short Circuit 38.3.4.5 Cell or battery case temperature does not exceed 170°C.  During test and within 6 hours after test, there shall be no disassembly, rupture or fire. Impact/Crash Test 38.3.4.6 Impact ( applicable to cylindrical cells not less than 18mm in diameter) Cell or battery case temperature does not exceed 170°C.  During test and within 6 hours after test, there shall be no disassembly, rupture or fire. Crush(applicable to prismatic, pouch, coin/button cell and cylindrical cell less than 18mm in diameter.) Cell or battery case temperature does not exceed 170°C.  During test and within 6 hours after test, there shall be no disassembly, rupture or fire. Overcharge 38.3.4.7 During the test and within 7 days after the test, The charged battery shall be no fire or disassembly. Forced Discharge 38.3.4.8 During the test and within 7 days after test, original or charged battery shall be no fire or disassembly.

  • Battery testing
    Summary In recent years, frequent global battery safety accident sparked international market concerns about the safety of the battery; At the same time, the national market regulators have stepped up efforts to produce those who taste quality to selective examination to the battery, make domestic battery manufacturers are faced with the challenge of raising the quality of the product. AGC Group Cell division focus in the field of mainstream country battery test requirements change, with major institutions to maintain good relations of cooperation, dedicated team for battery manufacturers, sellers and exporters provide one-stop battery testing and certification services, ensure the quality of the battery can meet the requirements of the relevant international standards. Battery testing classification is as follows: Fuel Cell Alkaline manganese cell dry cell Cellphone Li-ion battery button battery Laptop Battery Lithium Ion Battery Import and export of battery Cellular phone use lithium ion batteries Portable lithium secondary monomer battery NiMH battery NiCd Battery Standards and Regulations IEC 62133 Portable secondary batteries and battery safety standards IEC 61960 Portable secondary batteries and battery performance standards UN 38.3 The dangerous goods transportation test and standard manual revision 1 &2 fifth edition 38.3 clause ANSI C18.2 Portable secondary batteries and battery safety standards GB/T 18287 Mobile phone use lithium ion battery and battery pack specification IEEE 1725 Mobile phone standard of rechargeable batteries standards IEC 62281 Primary and secondary lithium batteries of transportation safety IEC 60086-4 A lithium battery safety standards IEC 61951-1 Portable rechargeable batteries, nickel cadmium battery IEC 61951-2 Portable rechargeable batteries - nimh batteries UL 1642 lithium battery UL 2054 Residential and commercial battery Test items Environmental test Electrical Testing low-pressure rated capacity temperature cycling Discharge Performance Thermal abuse Over discharge Mechanical testing Overcharging vibrate forced discharge mechanical shock high rate charge Free fall External short circuit extrusion Endurance life Heavy shock internal resistance Electrostatic discharge Charged to maintain and restore EMC Lab Evironment
