Hello folks,
I have one qution about the IEC 60601-2-10. It is a very old standard, when i handled project against IEC 60601-2-10, i faced a question as follow. To make it esay to understand, please see find the attached illustration.
In the standard, Cl 51.103 required a indication of output if energe exceed 10mJ per pulse. As shown in the illustration which waveform should i measure ?
My opinion is the burst (sum of a,b and c for case 1;sum of e,f,g and g for case 2), it represent one cycle delivering into patient.
Another opinion is that the energy shoud be measure in a, b or c separately for case 1 and e,f,g or h for case 2.
For the latter opinion, i think it is rare that one pulse can exeed 10mJ for stimulator, for instance, for a pluse (rectangular waveform) with duration of 200 µs (long enough), the amplitude of the waveform shoud be 223V.It is really very high for stimulator.therefore, it make this requirement meaningless.
Any one has idea about it?
thanks in advance.
