IEC62560 Clause 15 Test Circuit Figure 8 For Testing A Non- Dimmable Lamp
Product Introduction
The test circuit for testing a non-dimmable lamp 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.
