Hye friend,
I doing a safety test for one unit of CO2 laser, modeled QrayFRX. The test standard I used was IEC601-1, and I put under class 1, type BF.
The results that I got was failed. When I refer to the results, the measurement that failed are;
Earth leakage current NC - (limit value=0.5)- (result=1.704mA)
Earth leakage current SFC - (limit value=1.0)- (result=2.627mA)
How come this test can failed, what are the condition that can contributes to it....
I really hope anybody can helping me resolve this matters.,,,
If yours is connected to
permanent ac source which is electrically so connected that the connection can only be loosened with the aid of a TOOL then it actually passed the leakage current test (these limits are specifically stated in IEC60601-1 standard). The limits are 5mA (NC) and 10mA (SFC). Hope this answers your query.
