B.20.1 The enclosure of a battery-operated appliance incorporating an integral battery that uses metal-ion chemistry shall withstand the pressure generated when a cell vents during failure.

Compliance is checked by inspection after the tests of Clause 19 for batteries with a capacity less than 0,2 Ah, and measurement in the case of a) or by the test of b).

a) The total area of the unobstructed openings in the enclosure allowing gasses to pass shall be not less than the value specified in Table B.2; or

b) a volume of air of the amount specified in Table B.3 shall be injected through a (2,85 ± 0,05) mm diameter orifice into the enclosure at an initial overpressure of 2070 kPa ± 10 %. Test fittings used for the test shall not increase the enclosure volume by more than 3 ml. The overpressure within the enclosure shall drop below 70 kPa within 30 s without any unintended rupturing damage to the enclosure
