3.5. Statistical Sampling Required for Continued Compliance
For quality assurance of ongoing productions to comply with RFI interference limits, CISPR 22 Clause 7
stipulates a statistical sampling procedure. In summary, this rule states that the manufacturer should ensure
80% of the units must be in compliance with an 80% confidence level. Refer to CISPR 22, Clause 7 for a
detailed description of the sampling procedure.
3.6. Power Line Harmonics: EN 61000-3-2 (2000), A1(2001), A2(2005)
EN 61000-3-2 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. The objective of
this standard is to set limits for harmonic emissions of equipment onto the AC Power Line.
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 61000-3-2 publication (1995) in
addition to the test results section and photographs of the test set-up provided in this report.

3.7. Power Line Fluctuations/Flicker: EN 61000-3-3 (1995), A1(2001)
EN 61000-3-3 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 publication (1995) in
addition to the test results section and photographs of the test set-up provided in this report.
