This test evaluates the potential for the EUT to cause distortion on the AC power lines.  Testing was 
performed in accordance with EN 61000-3-2.  It is applicable to electrical and electronic equipment having an 
input current up to and including 16 amps per phase, and intended to be connected to public low-voltage 
distribution systems. 

 
Basic requirements of the AC source include a ± 2% voltage regulation and a ± 0.5% frequency limit.  A low 
distortion sine wave output is required to ensure that the AC source does not adversely contribute distortion to 
the load, meeting the following limits: 

 

o  0.9% for 3

rd

 order harmonics 

o  0.4% for 5th order harmonics 
o  0.3% for 7th order harmonics 
o  0.2% for 9th order harmonics 
o  0.2% for even harmonics of order 2 to 10 
o  0.1% for odd harmonic order from 11 to 40 

 
For further information, please refer to the technical sections in the EN 61000-3 in addition to the test results 
section and photographs of the test set-up provided in this report. 

 

 

 
Testing was performed in accordance with EN 61000-3-3.  It is applicable to household appliances and similar 
electrical and electronic equipment having an input current up to and including 16 amps per phase.  The 
objective of this standard is to set limits for voltage fluctuations of equipment within its scope, and ensures 
that home appliances and certain other electrical equipment do not adversely affect lighting equipment when 
connected to the same utility power line.  Large current variations combined with high utility line power 
impedance can cause excessive changes in the AC supply voltage.  If these voltage changes are repeated at 
short intervals, objectionable fluctuations of luminance (flicker) could be generated in illumination sources 
connected to the same utility line network. 

 
This test requires an AC power source with a standard impedance network and a power analyzer.  
Measurements of steady state and fluctuating harmonics, along with flicker and voltage deviations, are 
conducted using a power analyzer, often called a “flickermeter.” 

 
For further information, please refer to the technical sections in the EN 61000-3-3 in addition to the test 
results section and photographs of the test set-up provided in this report.

o  Criterion A - The equipment shall continue to operate as intended without operator intervention.  

No degradation of performance or loss of function is allowed below a performance level specified 
by the manufacturer when the equipment is used as intended.  The performance level may be 
replaced by a permissible loss of performance.  If the minimum performance level or the permissible 
performance loss is not specified by the manufacturer, then either of these may be derived from the 
product description and documentation, and by what the user may reasonably expect from the 
equipment if used as intended.  

 

o  Criterion B - During the test, degradation of performance is allowed.  However, no change of 

operating state or stored data is allowed to persist after the test. After the test, the equipment shall 
continue to operate as intended without operator intervention. The performance level may be 
replaced by a permissible loss of performance.  If the manufacturer does not specify the minimal 
performance level (or the permissible performance loss), then either of these may be derived from 
the product description and documentation, or by what the user may reasonably expect from the 
equipment if used as intended. 

 

o  Criterion C - Loss of function is allowed, provided the function is self-recoverable, or can be 

restored by the operation of the controls by the user in accordance with the manufacturer’s 
instructions. Functions, and/or information stored in non-volatile memory, or protected by a battery 
backup, shall not be lost. 

 
For each test method, the test standard specifies the appropriate criterion to be met.

This test simulates electrostatic events (similar to being “zapped” by touching a light switch) and evaluates the 
ability of the EUT to tolerate such events.  Testing was performed in accordance with IEC 61000-4-2.  
Tabletop devices are placed on an insulated mat on a horizontal coupling plane.  Air discharges and contact 
charges are made to the EUT on connectors and conducting surfaces (as illustrated in the Test Results section 
of this Test Report).  The discharges shall be applied in two ways: 

a)  Contact Discharges to the conductive surfaces and to 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 pints (a minimum of 50 discharges at each point).  One of the test points shall be 
subjected to at least 50 indirect discharges (contact) to the center of the front edge of the horizontal-
coupling plane.  The remaining three test points shall each receive at least 50 direct contact discharges.  If 
no direct contact test points are available, then at least 200 indirect discharges shall be applied in the 
indirect mode.   

b)  Air Discharge at slots and apertures, and insulating surfaces: 
On those parts of the EUT where it is not possible to perform contact discharge testing, the equipment 
should be investigated to identify user accessible points where breakdown may occur.  This investigation 
should be restricted to those areas normally handled by the user.  A minimum of 10 single air discharges 
of each polarity and test level shall be applied to the selected test point for each area.

the test results section and photographs of the test set-up provided in this report.
