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.
