Appendix 3.1 When the 9497 NETWORK B is installed
3.1.1 Medical Electrical Equipment Part 1: General Requirements of
Safety (IEC 60601-1 (1988-12) + am1 (1991-11) + am2 (1995-03))
Power supply Maximum rated frequency and 110% of the maximum rated power voltage
Points of measurement Between the protective earth terminal and the earth (Earth leakage current
measurement)
Between the enclosure and the earth
(Enclosure leakage current measurement)
Between parts of the enclosure
(Enclosure leakage current measurement)
Between the applied part and the earth
(Patient leakage current
and measurements)
Between the F-type applied part and the earth
(Patient leakage current
measurement)
For equipment with the enclosure made of insulated
material, attach a 10 cm
× 20 cm sheet of metallic foil.
Measurement network 1 k Ω // (10k +0.015 μ F)
(Use an appropriate measurement procedure when current or composite current
higher than 10mA with frequency higher than 1kHz is likely to exist.)
Allowable value 0.01 to 5 mA (Refer to Section 5.1, "Leakage Current Measurement Types and
Their Allowable Values for Medical Electrical Equipment.")
Condition of the
equipment to be
measured Normal condition and single fault condition
(Refer to Section 5.1, "Leakage Current Measurement Types measured and
Their Allowable Values for Medical Electrical Equipment.")
Measurement Measure with a voltmeter.
Points of measurement Between the applied parts
Allowable value 0.01 to 0.5 mA
(Refer to Section 5.1, "Leakage Current Measurement Types and Their
Allowable Values for Medical Electrical Equipment.")
(The others are the same as leakage current measurement.)
Appendix 3 Standards for Leakage Current and Current
Measurements
When the 9497 NETWORK B is installed, measurement conforming to the
following standard can be made.
Medical electrical equipment Part 1: General requirements of Safety (IEC
60601-1 (1988-12) + am1 (1991-11) + am2 (1995-03))
The polarity must be switched for leakage current and patient auxiliary
current measurements.
(1) Leakage current measurement
(2) Patient auxiliary current measurement
For details, refer to "Medical electrical equipment Part 1: General requirements of Safety (IEC 60601-1 (1988-
12) + am1 (1991-11) + am2
(1995-03))."
