Transportation of Dangerous Goods Regulations — 102
102 (1) Fuel cell cartridges that contain hydrogen in a metal hydride and that are transported under this shipping name must have a capacity less than or equal to 120 mL. The fuel cell cartridges must be designed and constructed to prevent fuel leakage under normal conditions of transport. (2) The pressure in the fuel cell cartridge must not exceed 5 MPa at 55°C. The design type must be capable of withstanding, without leakage or bursting, a pressure of at least two times the design pressure of the cartridge at 55°C or 200 kPa more than the design pressure of the cartridge at 55°C, whichever is greater. (3) Fuel cell cartridges must be filled in accordance with procedures specified by the manufacturer and the manufacturer must provide, with each fuel cell cartridge, the following information: (a) inspection procedures to be carried out before initial filling and before refilling of the fuel cell cartridge; (b) safety precautions and potential dangers; (c) method for determining when the rated capacity has been achieved; (d) minimum and maximum pressure range; (e) minimum and maximum temperature range; and (f) any other requirements to be met for initial filling and refilling, including the type of equipment to be used for these operations. (4) Each cartridge design type, including cartridges integral to a fuel cell, must (a) withstand a 1.8 m drop test onto an unyielding surface in the four following orientations: (i) vertically, on the end containing the shut-off valve, (ii) vertically, on the end opposite to the shut-off valve, (iii) horizontally, onto a steel apex with a diameter of 38 mm, with the steel apex in the upward position; and (iv) at a 45° angle on the end containing the shut-off valve; (b) show no leakage, determined by using a soap bubble solution or other equivalent means on all possible leak locations, when the cartridge is charged to its rated charging pressure; and (c) be hydrostatically pressurized to destruction with a recorded burst pressure that exceeds 85% of the minimum shell burst pressure. (5) Each cartridge design type, including the design types for cartridges integral to a fuel cell, must pass a fire engulfment test using a fuel cell cartridge filled to rated capacity with hydrogen. The cartridge design type, which may have a vent feature integral to it, is deemed to have passed the fire engulfment test if (a) the internal pressure vents to zero pressure without rupture of the cartridge; or (b) the cartridge withstands the fire for a minimum of 20 minutes without rupture. (6) Each cartridge design type, including the design types for cartridges integral to a fuel cell, must pass a hydrogen cycling test in which the fuel cell cartridge is cycled, for at least 100 cycles, from not more than 5% rated hydrogen capacity to not less than 95% rated hydrogen capacity and then back to not more than 5% rated hydrogen capacity. The rated charging pressure must be used for charging, and temperatures must be held within the operating temperature range. (7) Following the hydrogen cycling test, the fuel cell cartridge must be charged, and the water volume displaced by the cartridge must be measured. The cartridge design type is deemed to have passed the hydrogen cycling test if the water volume displaced by the cycled cartridge does not exceed the water volume displaced by an uncycled cartridge charged to 95% rated capacity and pressurized to 75% of its minimum shell burst pressure. (8) Each cartridge design type, including the design types for cartridges integral to a fuel cell, must pass a production leak test in which the fuel cell cartridge is tested for leaks at 15ºC ± 5ºC while pressurized to its rated charging pressure. There must be no leakage, determined by using a soap bubble solution or other equivalent means on all possible leak locations. (9) Each fuel cell cartridge must be permanently marked with the following information: (a) the rated charging pressure, in MPa; (b) the manufacturer’s serial num
