22、ped in any direction, to an angle of 35 degrees from the normal upright position without overturning on being released. 3.2.6 The appliance while operating or not operating and filled in accordance with Clause 7.1.7 shall not permit the escape of liquid fuel. This requirement shall be deemed met if

23、the appliance: (a) Will not leak liquid fuel when tilted to any angle up to 40 degrees in any direction from the normal upright position; and (b) When lying on its side for a period of at least 10 minutes, will not leak more than 2Y2 ounces of liquid fuel in any given minute. 3.2.7 The catalytic lay
