Appendix A Purpose of Tests
Insulation Test
Warning
1000V, 500 V, and 250 V D.C. test voltage
This test is used to verify that adequate insulation exists between the
mains supply pins and earth.
During the insulation test, a HV DC voltage is applied between the earth
pin and both the live and neutral pins of the Product mains supply plug.
The Tester displays the resistance measured and allows the user to
confirm sufficient insulation exists.
For a products that incorporates over-voltage protection, a 250V DC test
voltage is provided to allow a reading to be taken without the protection
devices generating a false failure.
Hipot Test
Warning
5000V a.c./6000V d.c. Test voltage
This test is used to determine that the insulation is of sufficient strength
to prevent breakdown, particularly where high transient voltages are
likely. This test can be omitted when testing equipment with component
whose voltage withstand rating is insufficient to accommodate the test
without damage. This is especially true of IT equipment.
For Class I Products, a nominal test voltage of 1.5kV AC RMS is applied
between the earth pin, and both the live and neutral pins of the Product
mains supply plug
For Class II Products, a nominal voltage of 3kV AC RMS is applied
between the Hipot probe tip and the live and neutral pins of the Product
mains supply plug.
