Protective insulation test
8.7.1 What is the protective insulation test about?
This test is necessary
-
for class 1 and 2 equipment (with/without protective earth)
-
after a repair whenever a general disassembly was performed.
8.7.2 General
Legal regulation
In case of a repair/modification of the coffee machine, the repair centre is bound by law
to protect the user/consumer by
-
restoring the regular condition of the appliance and
-
performing the respective tests according to EN/IEC 60335-1 "Safety of household
and similar electrical appliances" and national regulations (e.g. DIN VDE 0701).
Description
The insulation test
-
assures that wiring and insulation of the coffee machine fullfill the normative require-
ments after a repair,
-
rates the insulation capability of the coffee machine,
-
is a very dangerous test because of a high test voltage (500 V DC).
For the insulation test, phase and neutral wire are shunted at the power plug. Then a
test voltage is applied between phase/neutral and selected parts of the coffee machine.
Test equipment
Special test equipment is needed that complies with the regulations to perform insulation
and withstanding voltage tests. Detailed requirements and tolerances must be verified
with your local authorities or measurement supplier in any case.
Ideally the test equipment has a national power socket for testing, so that the coffee
machine can plugged in directly. Otherwise a special shunt is necessary to connect the
phase and neutral pin of the coffee machine's power plug.
Test report
For legal reasons a repair or test report should be prepared and filed with following infor-
mation
-
customer (name, address)
-
type and serial number of coffee machine
-
date of repair/test(s)
