Amendment 2 - Specification for radio disturbance and immunity measuring apparatus and methods - Part 1-6: Radio disturbance and immunity measuring apparatus - EMC antenna calibration
Specifies a procedure for the determination of the kinematic viscosity of mineral insulating oils, both transparent and opaque, at very low temperatures, after a cold soaking period of at least 20 h, by measuring the time for a volume of liquid to flow under gravity throught a calibrated glass capillary viscometer. Applies at all temperatures to both Newtonian and non-Newtonian liquids having viscosities of up to 20 000 mm2/s.

AMENDMENT 2
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 2 to CISPR 16-1-6:2014 has been prepared by subcommittee CISPR A: Radio-
interference measurements and statistical methods, of IEC technical committee CISPR:
International special committee on radio interference.
The text of this Amendment is based on the following documents:

magnetic field antenna factor
Replace the existing Note 1 to entry and Note 2 to entry as follows:
Note 1 to entry: The symbol F is used only when antenna factor is expressed in dB. The quantity F is expressed
aH aH
−1 −1
in dB(S/m) or dB(Ω m ).
Note 2 to entry: The unit dB(pT/µV) is used in some standards (but not in CISPR 16-1-6), which can be converted
to dB(S/m) by subtracting 2 dB.
Add Note 3 to entry:
Note 3 to entry: CISPR 16-1-4 specifies loop antennas for magnetic field strength measurements in the frequency
range of 9 kHz to 30 MHz.
3.2 Abbreviations
Add to the existing list the following new abbreviations:
CPM current probe method
SFM standard field method
5.2.1 General
Replace the second and third paragraphs by the following five new paragraphs:
Several techniques have been developed for calibrating loop antennas or measuring magnetic
field antenna factors [74]. Reference [18] provides a useful overview. Reference [15] provides
a simplified version of the standard field method (SFM) ([32] and [16]), and the TAM is described
in [35]. This subclause and Annex H specify acceptable calibration methods for loop antennas.
The TAM and the TEM cell method yield a standard uncertainty of measured antenna factor of
approximately ± 0,5 dB, while application of the TEM cell method is restricted to the frequency
range below the first resonant frequency of the TEM cell.
The current probe method (CPM) [15] is an improved SFM based on IEEE Std 291 [32]. In the
original method, the current flowing in the transmit loop antenna was measured using an RF
vacuum thermocouple built into the loop element; however, a thermocouple is typically small
and fragile, and therefore is not suitable for use in routine calibration measurements.
© IEC 2022
The Helmholtz coil method [34], categorized as a SFM, is accurate to 0,7 % (0,06 dB) up to
150 kHz, and better than ± 0,5 dB up to 10 MHz (see Annex H), but its applicable frequency
range depends on the coil size.
A sufficient signal-to-{receiver noise} ratio of at least 34 dB is necessary to obtain
