Toasters Abnormal Endurance Test Equipment,
Clause 19.101 Endurance Test Equipment
IEC 60335-2-9 Toasters Abnormal Operation Endurance Test Equipment
1.1 Applied standard and application
The toasters abnormal operation endurance test equipment complies with IEC60335-2-9 clause 19.101. It is used for testing toaster’s endurance under abnormal operation.
1.2 Test Principle
Toasters are operated at rated power input and under normal operation, but without bread, for six cycles of operation, the toaster is then forced to cool to approximately room temperature. This test is carried out 500 times. The ejector mechanism shall operate satisfactorily, and no sustained arcing shall occur. Electrical connections shall not work loose, and the appliance shall withstand the electric strength test of 16.3 of IEC60335-2-9.
It adopts a multi-function universal clamp, which can hold different samples and has strong versatility. It is suitable for testing most of the toasters.
The numbers of operation cycles, test times, temperature and current can be real-time displayed. The test equipment can stop testing automatically after the preset test times are reached.
|Input Power Supply||Single phase AC 220V, 50Hz or match client's local power supply requirements|
|Electrical Control Method||Button control|
|Sample Clamping Method||Mechanical clamping, the position of clamping points are adjustable|
|Cooling Method||Forced cooling by high-power cooling fan|
|Temperature Measuring Device||Infrared temperature measurement system, when the infrared probe detects that the temperature is cooled to the set temperature, the next test is started.|
|Interval Time of Pushing Switch||0-99.9s, can be preset|
|Operation Cycles||0-9999, can be preset, default 6 cycles|
|Test Times||0-9999,can be preset, default 500 times|
|Current Detecting Device||It is equipped with a device for automatically detecting the working current of the specimen: the upper and lower limits of the current detection can be adjusted, and with a light indicator indicating status.|
A. Preset interval time, test cycles and test times, preset room temperature, press [RESET].
B. Insert the plug of the test specimen into the socket on the test equipment, press the “START” button, the timing of interval time starts, when the display value of interval time reaches to the setting value, the switch opener manipulator goes downward. System counts one test cycle, when the switch opener manipulator turns the toaster’s switch on and the toaster starts heating, the switch opener manipulator runs upward to the upper limit position, after finishing the preset test cycles (6 times default), system counts one test time, and the fan is turned on to cool the toaster. After the preset value of test times is reached, the test equipment will stop testing.
