III. Conducted/Radiated Emissions Requirements (EMI)
3.1 General:
The conducted emissions test from 150KHz to 30MHz is employed to the
power line through a LISN (Line Impedance Stabilization Network). The
limits are 66-56dBuV(QP) / 56-46dBuV(Average), decreases linearly with the
logarithm for 0.15-0.50MHz; 56dBuV(QP)/ 46dBuV(Average) for
0.50MHz-5MHz; 60dBuV(QP) / 50dBuV(Average) for 5-30MHz.
The conducted emissions test from 150KHz to 30MHz is employed to the
telecommunication port through a ISN (Impedance Stabilization Network) or
Current Probe . The Voltage limits are 84-74dBuV(QP) / 74-64dBuV(Average),
decreases linearly with the logarithm for 0.15-0.50MHz; 74dBuV(QP)/
64dBuV(Average) for 0.50MHz-30MHz; Current limits are 40-30dBuV(QP) /
30-20dBuV(Average), decreases linearly with the logarithm for
0.15-0.50MHz; 30dBuV(QP)/ 20dBuV(Average) for 0.50MHz-30MHz;
The radiated emissions test is made at a 10 meters open site from 30MHz
to 1000MHz. The object of this test is to investigate the emissions from the
EUT in order to suppress interference to the environment. The limits are
30dBuV/m(QP) for 30-230MHz; 37dBuV/m(QP) for 230-1000MHz.
3.2 Test Specifications:
Requirement Comment Result (Pass/Fail)
EN 55022 Class B Conducted Emission 0.15-30 MHz
(Main Power Port) Pass
EN 55022 Class B Conducted Emission 0.15-30 MHz
(Telecommunication Port) N/A
EN 55022 Class B Radiated Emission 30-1000 MHz Pass
3.3 Setup:
The EUT is placed on a support of non-metallic, the height of which is
0.8m above the ground. For the conducted test, a LISN is used as a
matching network to the measuring receiver. The EUT is rotated and the
antenna's height vary between 1m and 4m for horizontal and vertical
polarization to obtain the maximum reading during the radiated test.

This standard is applicable to electrical and electronic equipment for
household and similar use, intended to be connected to low-voltage A.C
distribution system of the following types:
 nominal voltages up to 240V, single-phase, two or tree wire;
 nominal voltages up to 415V, three-phase, three or four wire;
 nominal frequency 50 Hz or 60Hz
Examples of electrical equipment to which this standard applies
are appliances for cooking and heating, motor-operated or magnetically
driven appliance, portable tools, light dimmers and radio and television
receivers.
This standard is not applicable to :
 equipment subject to notification to or consent by the supply
authority before connection to the system;
 equipment intended exclusively for professional purposes.

User’s operation controls or automatic programmer shall be set to
produce the maximum harmonic components, for each successive
harmonic component in turn.
A definition of the normal load or of the conditions for adequate heat
discharge can usually be found in the EN publication corresponding to the
equipment under test.
Equipment may have several separately controlled circuits. Each
circuit is considered as a single piece of equipment if it can be operated
independently and separately from the other circuits.

V. Electrostatic Discharge Requirements (ESD)
5.1 General:
This requirement relates to the EUT may be involved static electricity
discharges owing to environmental and installation conditions. A transfer of
electrostatic charge between objects of different electrostatic potential
may cause harmful to the EUT. A performance Criterion is classified as A, B,
C the recommendation is Criterion B.
5.2 Test Specifications:
Requirement Basic Standard Performance
Criterion
EN 55024 EN 61000-4-2: 1995+A1: 1998+A2: 2001 Criterion B
Criterion A: The equipment shall continue to operate as intended without
operator intervention.
Criterion B: After the test, the equipment shall continue to operate as
intended without operator intervention. During the test,
degradation of performance is allowed. However, no change of
operating state or stored data is allowed to persist after test.
Criterion C: Loss of function is allowed, provide the function is
self-recoverable, or can be restored by the operation of the
control s by the user in accordance with the manufacturer’s
instructions.
5.3 Setup:
The discharge shall be applied in two ways:
1.Contact discharge to the conductive surfaces and coupling planes:
The EUT shall be exposed to at least 200 discharges, 100 each at
negative and positive polarity, at a minimum of four test points. One of
the test points shall be subjected to at least 50 indirect discharges to
the center of the front edge of horizontal coupling plane. Test shall be
performed at a maximum repetition rate of one discharge per second.
