INTRODUCTION
Amendment of CISPR 16-2-3 regarding EUT volume specifications for radiated disturbance
measurements depending on test method and on measurement distance
2 Normative references
Replace the undated reference to CISPR 16-4-2 by the following:
CISPR 16-4-2:2011 , Specification for radio disturbance and immunity measuring apparatus
and methods – Part 4-2: Uncertainties, statistics and limit modelling – Measurement
instrumentation uncertainty
CISPR 16-4-2:2011/AMD1:2014
CISPR 16-4-2:2011/AMD2:2018
__________
A consolidated version of this publication exists, comprising CISPR 16-4-2:2011, CISPR 16-4-
2:2011/AMD1:2014 and CISPR 16-4-2:2011/AMD2:2018.

Replace the dated reference to CISPR 16-1-4 by the following:
CISPR 16-1-4:2018, Specification for radio disturbance and immunity measuring apparatus
and methods – Part 1-4: Radio disturbance and immunity measuring apparatus – Antennas
and test sites for radiated disturbance measurements
3.1 Terms and definitions
3.1.1
absorber-lined OATS/SAC
Add the following note:
Note 1 to entry: CISPR 16-1-4 uses the analogous term free-space open-area test site (FSOATS).
3.1.9
common-mode absorption device
Replace the existing source by the following:
[SOURCE: CISPR 16-1-4:2018, 3.1.7]
3.1.16
loop-antenna system
LAS
Replace the existing term by the following new term and new abbreviation (the definition does
not change):
large loop-antenna system
LLAS
The instruction to replace the existing Note to entry only applies to the French language.
Add, after the existing term and definition 3.1.28, the following new terms and definitions:
3.1.29
compliance test site
COMTS
environment that assures valid, reproducible measurement results of the disturbance field
strength from equipment under test for comparison to a compliance limit
3.1.30
far-field region
region of the electromagnetic field of a radiating EUT or antenna where the predominant
components of the field represent a propagation of energy and where the radiation pattern is
essentially independent of the distance from the radiating EUT or antenna
Note 1 to entry: In the far-field region, all the components of the electromagnetic field change with an inverse
proportion to the distance from the radiating EUT or antenna.
[SOURCE: IEC 60050-712:1992 [14], 712-02-02, modified – Replacement of "far field region"
by "far-field region" in the term itself, replacement of "antenna" by "radiating EUT or antenna",
replacement of "angular field distribution" by "radiation pattern" and deletion of Note 2 to
entry.]
3.1.31
near-field effect
deviation of the field propagation from far-field propagation
Note 1 to entry: The near-field effect occurs in the zone close to the EUT where reactive (non-radiating) field-
strength components exist. Although not contributing to far-field radiation, they are real measurable field strengths.

– 4 – CISPR 16-2-3:2016/AMD1:2019
© IEC 2019
Note 2 to entry: A criterion can be set to limit the deviation from far-field propagation, e.g. 1 dB. If E and E are
1 2
field-strength levels in dB(µV/m) at distances d and d from an EUT, then e.g. the following inequality describes
1 2
the criterion: (20lg(d /d ) − 1 dB) ≤ (E − E ) ≤ (20lg(d /d ) + 1 dB), which can be reduced to −1 dB ≤ [(E – E ) −
2 1 1 2 2 1 1 2
20lg(d /d )] ≤ 1 dB, where (E – E ) ≥ 6 dB.
2 1 1 2
3.1.32
test volume
validated volume within a test facility in which an EUT may be positioned
Note 1 to entry: Validation procedures in CISPR 16-1-4 are used to determine the test volume.
Note 2 to entry: The test volume as defined in this document is cylindrical in shape. Different test volume shapes
have been defined in other documents, e.g. in a cubic form in IEC 61000-4-20 (TEM waveguides).
3.1.33
EUT volume
cylinder defined by EUT boundary diameter and height that fully encompasses all portions of
the actual EUT, including cable racks and 1,6 m of cable length (for 30 MHz to 1 GHz), or
0,3 m of cable length (for 1 GHz and above)
Note 1 to entry: The test volume is one of several criteria limiting the EUT volume.
Note 2 to entry: The EUT volume has a diameter D (boundary diameter) and a height h.
3.1.34
protection distance
distance between the source of a radiated disturbance and the victim receiver at the edge-of-
service area used for the derivation of a specific CISPR radiated disturbance limit
Note 1 to entry: The edge-of-service area is defined by the minimum value of the wanted field strength of a radio
service or application derived from ITU-R specifications.
Note 2 to entry: This definition can vary in other publications, when conducted disturbances are concerned.
Note 3 to entry: Every limit has an associated protection distance; the protection distance can vary with frequency.
3.1.35
small EUT
equipment under test, including its cables, either positioned on a tabletop or standing on the
floor, that fits in a cylindrical volume of 1,5 m (2,0 m) in diameter and 1,5 m (2,0 m) in height
measured from the floor with a measurement distance of 3 m (5 m) at an OATS/SAC
3.2 Abbreviated terms
Delete from the existing list the abbreviation “RGP”.
Add to the existing list the following new abbreviations:
AF Antenna factor
FSOATS free-space OATS
GP ground plane
HPBW Half-power beamwidth
RE radiated emission
RI radiated immunity
6.2.2 Compliance (conformity assessment) testing
st
Replace in the 1 sentence “test site” by “compliance test site (COMTS)”
6.4.1.1 General
Replace in the existing twelfth paragraph the abbreviation “RGP” by “GP”.

6.4.1.2 Tabletop arrangement
Replace in the existing third paragraph the abbreviation “RGP” by “GP”.
6.4.1.3 Floor-standing arrangement
Replace in the existing first three paragraphs the abbreviation “RGP” by “GP”.
6.4.1.4 Combinations of tabletop and floor-standing equipment arrangement
Replace in this subclause the abbreviation “RGP” by “GP”.
7.1 Introductory remarks
Replace the existing title by the following new title:
7.1 General
Replace the existing content of this subclause (including Table 3), by the following new 7.1.1,
and 7.1.2:
7.1.1 General remarks and overview of test methods
Clause 7 sets forth the general procedures for the measurement of the field strength of radio
disturbance produced by devices and systems. Most experience with radiated disturbance
measurements exists for OATS/SAC with 10 m distance in the frequency range 30 MHz to
1 000 MHz. In this frequency range this is
