COMMON APPLIANCES

TESTS

1 EARTHED APPLIANCES CLASS I

insulation resistance test isolated from protective earth

Suitable appliance category for testing any earthed equipment. Recognised as an appliance with exposed metal parts

This test is conducted with the standard 500VDC. electrical strength test. Applied to obtain an insulation resistance

figure which is required to be above 1 M ohm. for a PASS result.

Select EARTHED APPLIANCES

Press START

Measures: Electrical continuity (A –N) …………….. less than 100k ohm……………………………….. for PASS

Earth resistance (socket earth to chassis earth with earth probe connect)…….less than 1 ohm…….PASS

Insulation resistance (A , N shorted to EARTH)………..greater than 1M ohm……………………PASS

2 DOUBLE INSULATED CLASS II

insulation resistance test isolated from protective earth

Suitable appliance category for testing any double insulated equipment. Recognised as an appliance with no exposed

metal parts. It may have a 2 or 3 pin plug where the latter has a functional and protective earth cord. The standard dou-

ble appliance insulation strength test at 500Vdc.. A cloak or probe must be employed in contact with the insulation

surfaces of the appliance during test, until completed.
