Abnormal operation
19.101
60335-2-69(ed.3)
Question:
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.
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.
Because the same situation is present in commercial water suction cleaners, is it possible to apply the same during test stated in 19.101 of EN 60335-2-2 (30 sec) for commercial water suction cleaners?
Rationale: see question
Proposal (if any):
The standard is clear. The test should be performed for the time stated in the current standard (5 min) avoiding the burning of the motor.
