In sub clause 19 of EN 60335-2-69 the overflow test of sub cl 15.2 has to be made again with the shut-off device made inoperative. This should be done for a period of 5 min, after the container is filled completely.* q3 _, K* @$ ~( u! J- Z! J7 E
In the past the same test was mentioned in the EN 60335-2-2. Because there were a lot of problems with the temperature rise of the windings of the motor, sometimes the motor was burnt, a proposal was made to reduce the time to 30 s. (see EN 60335-2-2:2003 sub cl 19.101 household water suction appliances). It was accepted because the meaning of the test was to look if the overflow of the water, should give a hazard situation.
