Test Requirements
A.
General
1.
Choice of equipment under test
In the case of series-manufactured products, the
equipment under test (EUT) shall be taken from the
current production cycle. The choice of equipment
under test shall be agreed with GL.
Example of use:
Equipment subject to the Rules for Classification and
Construction except for the tests "Electrostatic Discharge, Conducted fast transients (burst) and Conducted slow transients (surge) ".
–
The EUT shall continue to operate as intended
after the test. No degradation of performance or
loss of function is allowed, as defined in the relevant equipment standard in the technical specification published by the manufacturer. During the
test, degradation or loss of function or performance which is self-recoverable is, however, allowed, but no change of actual operating state or
stored data is allowed.
If the equipment under test is a prototype, GL reserve
the right to carry out subsequent comparative tests on
series-manufactured products.
2.
Test sequence
There is no pre-defined test sequence. Before the start
of the tests, the manufacturer shall determine the
sequence and notify GL accordingly.
All the tests required for the product shall be performed on one equipment under test. Any alternative
arrangements are subject to consent.
3.
Procedure of immunity tests to electromagnetic environment
For these tests the EUT shall conform to its normal
operational configuration, mounting and earthing
arrangements and shall operate under mentioned test
conditions.
Example of use:
Equipment not subject to the Rules for Classification
and Construction and the tests "Electrostatic Discharge, Conducted fast transients (burst) and conducted slow transients (surge)" for equipment subject
to the Rules.
–
Common mode tests (line/earth) are those applied
between groups of lines and a common reference,
normally earth.
For the tests the results are evaluated against performance criteria relating to the operating conditions
and functional specifications of the EUT, and defined
as follows:
–
performance criterion A:
The EUT shall continue to operate as intended
during and after the test. No degradation of performance or loss of function is allowed, as defined in the relevant equipment standard and in
the technical specification published by the
manufacturer.
performance criterion C:
Temporary degradation or loss of function or
performance is allowed during the test, provided
the function is self-recoverable, or can be restored at the end of the test by the operation of
the controls, as defined in the relevant equipment
standard and in the technical specification published by the manufacturer:
Particular interfaces of the EUT with the external
electromagnetic environment are referred to as ports.
The physical boundary of the EUT through which
electromagnetic fields may radiate or impinge is the
enclosure port.
Differential tests (line/line) are those applied between
electrical power, signal and control lines.
performance criterion B:
Example of use:
Equipment not subject to the Rules for Classification
and Construction.

General instructions for test performance
The equipment under test is fastened by means of its
fastening devices in its normal mounting position in
accordance with the manufacturer's instructions.
The tests are performed in three mutually perpendicular axes (X:Y:Z).
During the tests the functions shall be demonstrated
on the equipment under test.
At the start of the test the points of resonance of each
axis are determined.
If points of resonance are determined at tests according to curve 1, 2 and 4 on the equipment under test
which have an amplification factor Q < 2, the test
duration is 90 minutes per axis at a frequency of 30
Hz. For tests according to curve 3 a sweep over the
complete frequency range with a duration of 120
minutes has to be performed in that case.
If points of resonance are determined on the equipment under test which have an amplification factor
Q ≥ 2, the test duration is 90 minutes per resonance
frequency.
In the case of several resonance frequencies are detected close to each other a sweep test can be chosen.
The test duration is 120 minutes.

General instructions for test procedure
The radiation limit at distance 3 m from the enclosure
port over the frequency range shall be measured.
The quasi-peak measuring receivers specified in
CISPR 16-1-1 shall be used. The receiver bandwidth
in the frequency ranges 150 kHz to 30 MHz and
156 MHz to 165 MHz shall be 9 kHz, and in the
frequency ranges 30 MHz to 156 MHz and 165 MHz
to 2 GHz shall be 120 kHz.
For frequencies from 150 kHz to 30 MHz measurements shall be made of the magnetic H-field.
The correction factor for the antenna shall include the
factor + 51,5 dB to convert the magnetic field
strength to equivalent electric field strength.
For frequencies above 30 MHz measurements shall
be made of the electric E-field.
The test antenna shall be placed at a distance of 3 m
from the EUT. The centre of the antenna shall be at
least 1,5 m above the ground plane.
The E-field antenna shall be adjusted in height and
the EUT shall be placed at the mid-point of a plane
orthogonal to the test antenna and be rotated to
achieve the maximum emission level.

Test result
The radiation limit from the enclosure port shall not
exceed the limits shown in Fig. 3.19.
