Operating manual for the TG uni 1, TG euro 1 and TG euro 1 med appliance tester
Conducting tests in accordance with VDE 0751-1/EN 62353 – Definition of standards
48
The limit values differ according to the following applied parts (see also
Table on Page 49):
B
Applied part B
For application and/or body contact (B=body), earthed
B F
Applied part BF
For applications and/or body contact (B=body), not earthed
(F=floating)
C F
Applied part CF
For applications and/or body contact and/or heart contact
(C=cardio), not earthed (F=floating).
15.5 Leakage currents
Depending on the type of the ME device it may be necessary to measure
the device leakage current or the applied part leakage current (previously
known as the patient leakage current), the required measurements depend
on the equipment used and the classification of the ME device, the
manufacturer’s specifications must be followed here.
The following measuring methods can be used for this:
–
Alternative measurement
–
Direct measurement
–
Differential current measurement
Leakage currents must not exceed the permissible values listed in Table 1
on Page 49 (see also DIN VDE 0751-1 Table 2).
