rated charging pressure. The fuel cell cartridge shall then be hydrostatically

pressurized to destruction. The recorded burst pressure shall exceed 85% of the

minimum shell burst pressure.

Fire test

A fuel cell cartridge filled to rated capacity with hydrogen shall be subjected to a

fire engulfment test. The cartridge design, which may include a vent feature integral

to it, is deemed to have passed the fire test if :

(a) The internal pressure vents to zero gauge pressure without rupture of the

cartridge; or

(b) The cartridge withstands the fire for a minimum of 20 minutes without

rupture.

Hydrogen cycling test

This test is intended to ensure that a fuel cell cartridge design stress limits are not

exceeded during use.

The fuel cell cartridge shall be cycled from not more than 5% rated hydrogen

capacity to not less than 95% rated hydrogen capacity and back to not more than 5%

rated hydrogen capacity. The rated charging pressure shall be used for charging and

temperatures shall be held within the operating temperature range. The cycling shall

be continued for at least 100 cycles.

Following the cycling test, the fuel cell cartridge shall be charged and the water

volume displaced by the cartridge shall be measured. The cartridge design 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.

Production leak test

Each fuel cell cartridge shall be tested for leaks at 15 °C ± 5 °C, while pressurized to

its rated charging pressure. There shall be no leakage, determined by using a soap

bubble solution or other equivalent means on all possible leak locations.

Each fuel cell cartridge shall be permanently marked with the following

information:

(a) The rated charging pressure in MPa;

(b) The manufacturer's serial number of the fuel cell cartridges or unique

identification number; and

month in two digits).
