5. Safety Analysis Test
5.1 General introduction
The suggested Safety Analysis Tests refer to the international standard IEC 601-1.
The tests are generally performed with Safety Testers, on most of them, the measuring
circuits according IEC 601 are already implemented.
The following is a general description of the tests to be performed. For the handling of
your Safety Tester follow the user manual.
The tests may be performed under normal ambient conditions of temperature, humidity
and pressure and with line voltage.
The leakage currents correspond to 110 % of rated voltage for the tested unit. Most Safety
Testers take this into account, otherwise the measured values have to be calculated.
5.1.1 Recommended Test Equipment
- Safety Tester for measurements according to IEC 601.
- Testing connector according to the following description.
5.1.2 Leakage Current Measurement
To perform the suggested measurements, the unit under test has to be separated from
any interconnection to a system. If the unit is part of a system, extended tests according to
IEC 601-1-1 have to be performed. The following diagram shows the Measuring Circuit [M]
required for leakage current. The reading in mV corresponds to µA (leakage current). The
Safety Testers generally work with this Measuring Circuit [M] and the displayed values are
already converted to leakage current.
