Test Circuit For Testing Non-Dimmable Lamp Or Electronic Switch Fig8
Standards:
The test circuit for testing a non-dimmable lamp or electronic switch is manufactured according to IEC62560 clause 15 figure 8.
Standard description:
15.Abnormal operation
Self-ballasted lamps shall not create hazard under abnormal operating conditions .
Self-ballasted lamps shall be constructed so that as a result of abnormal or careless operation ,the risk of fire and mechanical damage impairing safety of protection against electric shock is obviated .
Appling non-dimmable self-ballasted lamps on a diameter or an electronic switch is to be tested as a possible case of abnormal operation .
Test procedure :
Test non-dimmable lamp in test circuit shown in figure 8.
Determine R1 and S1 setting at which the maximum I r.m.s occurs.
Test at this situation ,and if the lamp passively fails within 60 min ,repeat the test at 10% lower I r.m.s. The lower I r.m.s shall be set in the decreasing potentiometer resistance direction .
Repeat this procedures until stable operation is achieved for minimum 60 min .
Operate the lamp fpr 8H at the above most onerous dimming level (potentiometer adjustment )
Compliance:
Compliance is checked by operating the sample free burning ,vertical cap up position or in the burning position indicated on the packaging at room temperature and at the rated voltage .
In case a voltage range is declared ,the test has to be carried out at the mean voltage of that declared range .
In case of alternative rated voltages ,the test shall be performed separately for each rated voltage .
During this test the lamp shall not catch fire ,or produce flammable gases and live parts shall not become accessible with the standard test finger .
Notice:
1. Please do not damage the appliance shape (such as scratching, bending, etc.).
2. Prevented from dust and moisture environment, in order to avoid the oxidation to affect the dimensional accuracy.
